Are wheel spacers safe? Are wheel spacers a good idea?

How will wheel adapters affect handling? What effects will wheel spacers have on suspension geometry? Wheel spacers can help with fitting big brake kits, altering wheel offset if aftermarket wheels are used, and can widen a car's track, thus reducing load transfer and ideally improving handling. That said, wheel spacers affect suspension geometry, and will change the scrub radius, affecting braking stability, and also reduce the effective spring rate at the wheels. Wheel spacers can also cause wheel bearing failure.

3rdpartyU5er I should have been more specific. Wondering about the load on the bearing. Pretty sure if the center goes out farther that creates a bigger load on the bearing, but if it stays in the center or is moved in closer to the hub is either of those bad too?
@3rdpartyU5er
@3rdpartyU5er 8 жыл бұрын
Well it depends on the centre hub of the rim because as you said it yourself as the hub goes further away the bearing gets more load but then again depends on the rim because there are quite a few different rims that have the hub on different location because of the width of the rim. You have no worries if the wider tires have the hub on same position as in stock tyres and what I mean is that you measure the hub distance from the inner end of the rim to the hub. So the wider wheel may be the same as stock wheel but after the hub the rim has a bigger lip for wider rubbers. This should not stress your suspension.

I have like 3 inches of spacers 2) 1"1/2 stacked on each other PLUS bigger wheels 20" instead of 17" AND I have coilovers that lowered the car 2 inches but that wasn't enough so I cut a coil of the spring too! Giving me about 3 inches of drop on a 2012 mercedes c250 coupe. So thats 3 inches and a much stiffer suspension... I've had the car this way for like I donno 2 years or like 50,000 miles... the only problems I had was I tore the boot on my cv joint in the back, (rear wheel drive) and the subframe bushings are pretty shot... but my bearings are fine! The car is fine... this smells like a hater video... but I appreciate it and I love all EE videos.. I do agree the car probably handles better stock!

some things you just have to accept you will replace. I know a few hardcore racers, on wheelbearings for instance they plan on running through 2-3 sets in a year. and sometimes Modifications dont change enough to make much difference. It is a good point though, especially on a daily driver. then theres the stance crowd that thinks sparks coming off an undercarriage is cool, and run camber that grinds through bearings at an alarming rate considering they are on public roads and most are too cheap to keep them fresh.

After adding 15mm spacers to the rear of my car, I've noticed a significant difference vs. them not being there. With the spacers, the rear suspension feels a lot softer, almost too soft, so confidence in the corners is reduced. The car looks better with them on, but I think I'll be removing them soon.

for the last point, even without wheel spacers, if the wheel has more offset it'll wear the bearings out faster. but if the wheel is wider towards the center of the axle it could compensate the offset and thus have normal wear characteristics.

Pyry Mustonen Let me explain what he meant. I for example had 18x7.5 with 45 offset. I bought aftermarket wheels 19x8.5 with 40 offset. Due to the wheels being 1 inch wider but only 5mm less in offset, my wheels stick out around 18mm more. Therefore my wheels are also around 8mm wider on the inside, which results in less space between my suspension and my wheels, but also less leverage on my bearings

Very true but in the case of spacers not wheel offset the wheel doesn’t get wider. If you do spacers and wider wheels the wheel is still push outward more which still moves the center of the wheel out further from the car.

The major issue with wheel spacers is the safety factor....bearing, scrub radius change, loading of springs, etc ALL negatively contribute to possible problems that can result in an unsafe car. A wider wheel can give the same issues but often those wheels are wider both on inside and outside so yield the same tire position relative to stock. In many countries use of wheel spacers is illegal. If you think you are a better engineer than the people that designed your car...go ahead and mess with spacers but I would never use them on my SCCA race car or my street cars. Just get a PROPERLY specd set of wider wheels and tires.

The biggest threat of wheel spacers is indeed the change in Scrub Radius and in Kingpin offset. In short: you could be altering your NEGATIVE scrub radius to a POSITIVE radius, with the result being you slipping all over the place when one wheel is on a surface with less friction (Icy spots, gravel, etc.). The other problem lies with your increased kingpin offset and having a lot of power driven to the front wheels, which results in massive torque steer. Hope it's any help!

This made a huge difference in ride quality, 2mpg increase, and noise abatement. However, the overall track was pulled in quite a bit. The spacer just pushed the thinner tires out to the original track width (outside to outside).

Years ago when I was about 8, I can remember helping ( more likely hindering) my father to jack the family car up and put wheel spacers on it. He did this every summer just before we hitched the caravan on it to go on our holidays. Only more recently did he explain, that he did this to add more stability to the rear of the car whilst towing the caravan. As soon as we returned home we would jack it up again and take the spacers back off. Even back then I recall the car looked skinnier once they were off again, but, for him, that was their purpose. I came here for information and I got plenty! Guess I will leave my car as the designers intended now, as there seems to be less advantages for and more against doing it.

Remember that adding a wheel spacer is the equivalent to going to a wheel with a different offset. Also, the wider track allows more stability during those off-camber situations when you are out wheeling. The cheaper wheel spacers are often not hub centric, so they can potentially put undesirable loads on the lug studs and result in more radial runout.

Say you have an OEM size of 18x8 +50 and you want to upgrade to 19x8.5 +35 - because you've added a half inch of width does that counter the .6 inch wheel offset increase and now the center line of the tire has not moved out as much? 8.5 +35 is optimal vs 8 +35?

I never bothered to figure it out to be sure, but I believe that per the original design of vehicles, the steering axis is intended to be right in the center of the wheel/tire and you want to stay in that vicinity as much as possible. Why? How? That's for the engineers to determine. I am not smart enough to know stuff like that.

Having hub-centric spacers is the same as having low offset wheels. Most people say they are bad but I have personally seen some of the fastest race cars in the world use them to great effect. Some of these cars generate in excess of 1000kg of downforce and i have spoken to the engineers and they have not seen a single bearing failure. Porsche even supplies them as an option on some of their models.

The fastest race cars in the world are also usually rebuilt with completely new bearings (not to mention valves, spark plugs, pistons, shocks etc) so frequently that it isn't allowed to become an issue -- in some cases after every single race. They never see failures because the components that could fail are never ran long enough to even come *close* to failure let alone performance-degrading wear -- unlike your average "tuned daily driver" that will see 15,000 street miles a year but only ever have the wheels off when it's time to put new brakes or rubber on.
@boblast5582

wheel spacers can also decrease the scrub radius (and everthing associated with it) as some cars have king pin geometry that puts the scrub radius to the outside of the wheel centerline. Also, the spring rates affects, and everything else mentioned in section 3 after the king pin/scrub radius part, is affected about as little as the lateral load transfer. The only affect a driver would feel from wheel spacers is the scrub radius change, everything else is too small of a change to feel from behind the wheel (although your wheel bearings may feel it). Also worth noting is everything mentioned in this video is general wheel offset information. For example if you have a +10 offset wheel and a +20 offset wheel with a 10mm spacer (all else being equal), both wheel will have the same affect on the rest of the car and geometry. The +10 wheels with no spacers aren't gonna magically put less load on your wheel bearings. I know this part sounds simple but I've had to explain it to a surprising amount of people.

From an engineering point of view I agree with everything you are saying... considering the safety factor that is built into all vehicle components what is the real effect when spacers are used on vehicles that are mostly daily drivers... surely it cannot be that bad? Of course there are limits but will these limits be that easily exceeded by the ordinary motorist?

just an FYI if you align it and fix the caster then turning won't be as difficult and the tire wear won't change. you may need to change some arms to adjustable arms so that you can get those adjustments, but then it will wear the tires properly. I run an alignment shop with 30 years of experience there, we can get tires to wear properly no matter what kind of mods you do to your car.

You should probably do a video on caster and the importance of it, also for those who like to camber their wheels way negative, explain the issues with that. Less rubber contact, tire wear even with compensating toe for camber, easier to hydroplane the car, and many other issues for ride quality and handling.

Engineering Explained but I will say not a lot of people will catch the fact that the bearing will wear faster with the issues of spacers... another idea is the huge rims issues... I aligned a car that had 26" rims, we had to weld and reinforce both sides of the frame (the frame was broken on the right front where the lower control arm bolts on due to the wheels), replace all ball joints and tie rods due to the excessive size of the rim it was wearing it all extremely fast since the small car wasn't meant to handle that force of turning when moving with the wheels. Just trying to turn the vehicle while going 25 was extremely suprising. The centrifugal force of the rims make you slow down considerably to make turns otherwise it won't cut it. Plus the rotors were warping and needed a big brake kit or really good rotors to avoid the warping when trying to slow the car down. The bill came to about 3k due to the hours spent on it.

You will also generally need extended lugs with spacers. It can be dangerous when people use the stock lugs since there's less threads available for the lug nuts to grab onto. Aftermarket wheels in the offset you're trying to get with spacers don't have this problem.

If you do decide on going with lowering springs and spacers you should install your springs first. Once you have installed your springs you need to drive it for about a week or 2. This will cause the new springs to compress and settle in. Once your new springs have settled in you can begin to measure how much room you have to install a spacer that won't rub. Cheers

@d1sturb3d119 8 жыл бұрын
18bagabooo That's the problem then. The instability isn't caused by a scrub radius change. That is a very minute change that can only be felt under hard acceleration out of corners. Using spacers creates more leverage on control arms. More leverage means that you change your static ride height ever so slightly. If the ride height changes the alignment specs all change. If you haven't lowered your car camber is not an issue. The change in toe is the issue. Look at what the stock specs are and adjust for that. If you like it then keep it or adjust further from there. I guarantee your toe is off by quite a huge margin. When I did my car the rear was set to 0.05 toe out stock but then moved to 0.25 toe out after I lowered it. The car cornered very well but was way to aggressive and would lose the back end sometimes. Get an alignment and you'll see the difference.

well done video man. another item to cover is increased rotational weight. rotational weight has a much higher impact of the performance of a car than static weight. while wheel spacers might only add a few pounds per wheel, the impact could be much greater because it is weight added to a rotating assembly.

The negative effects would actually be more notable than the positive ones, since the negatives are produced from a relatively larger change than the positive effects are. To better explain, an extra 20mm on either side of the vehicle will increase stance by some incredibly small percentage over the relatively large total distance between the wheels... However, the same 20mm added on to the hub will be a much larger change when measured against the individual suspension components, since everything is much closer inside each wheel well.

I enjoy watching your videos, sometimes they put me in the right general direction when looking for info! One comment I would like to make is regarding the old chestnut on how "engineers designed the car the best it could be, etc., etc.". News flash, car business is about bottom line and in 99.9% cases. The only driver is how to manufactore it the cheapest and so it doesnt fall apart before the warranty expires. Performance is the last thing on their minds, notable exception are performance models like M-series, AMG, and so on. There are some tests done by enthusiasts in Europe where they gathered together a number of fellow petrolheads owning the same car in different modification stages, perhaps best was m135i test. I write this to respond to your maths line where you claim track widening is neglidible in terms of grip increase. This might be so, I cannot be bothered to run the numbers really. On the same note have you run the numbers on how much difference would an increase of say 20mm per wheel effect on said lever arm force? You would find it negligible as well :)! That's one thing. The other is handling characteristics. Even if your mentioned physics maths calcs prove the theoretical grip increase is low I am pretty confident you would struggle in the handling characteristics department. This is where a driver gets the confidence to push from and times on track drop massively. To sum up the lowest times were recorded by cars with widened track and lowered suspension, not the ones with more power or better brakes. Tyres were if not the same then all of the performance variety. Driver and passenger were the same. Don't get me wrong, I am not trying to knock you and your vids can only be so long. It is worth to perhaps get out from behind the (in front of?) a white board (and you do need a bigger one and perhaps somebody to do the drawings for you ;)) and check stuff in real life. If you are planning to keep driving your car for over 100k miles then do not modify it at all, just service religiously and tune it from time to time. Otherwise stop worrying and slap on those (high quality hub centric) spacers and take great pleasure from better stance and (disputably) improved handling characteristics. Keep up the good work!

this video doesn't tell you what to do with your car, he's just telling you what happens if you do modify your car. Yeah wheel spacers help, like a spare tire, but if you do decide to use wheel spacers on the long run, you'll get consequences. any car mods comes at a cost, you pay cheap now and break things later down the line, or spend the extra money, get a better aftermarket wheel offset and lighter wheels, and you will have that same load on the bearing as stock but with bigger, cooler looking wheels. I'm not talking about cheap China imitation wheels, but engineered wheels like BBS, HRE, or something the likes down this manufacturer lines.

If i buy another exact same model of the wheel with extra 5mm offset wouldn’t it be an extra bit of material at the wheel’s face like the spacer being welded to the face of rim
