Wheel Spacers and Shout Outs - Porsche 911 991

[@karlhuy1115]

James you mentioned the torque specification when you were putting the tires back on. Do you know of a quick reference source where 991.1 owners can verify what their torque specs are? Thanks. Oh and keep up the great videos.

[@AutoAmateur]

Thanks Karl!! The correct torque for the 991.1 is 118 ft. lbs. The best place to look is always you’re user manual in true glove box, believe it or not. Otherwise you’re at the mercy of trying to figure out who to believe online across the various websites and forums.

The Negatives The main issue with a wheel spacer is that it moves the wheel to a wider position whilst the rest of the suspension arms remain in the same place. In particular, the king pin inclination axis remains in the same place. Therefore, fitting a wheel spacer moves the wheel outboard and alters the scrub radius of the car. It is important to know whether your car currently has negative or positive scrub radius and ideally how much it has. Fitting a wheel spacer will increase the positive scrub radius at the front wheels which has some unfavorable consequences. If your car already has a bit of positive scrub radius then the wheel spacer will increase it. An increase in positive scrub radius increases the forces on the steering rack under braking conditions. Any bumps in the road will also be amplified through the steering wheel, making the steering jerky and more unpredictable. Twitching wheels when braking can cause the tire to lose grip and ultimately can cause the wheels to lock up and slide. An increase in positive scrub radius also causes the wheel to gain positive camber when the wheels are being turned, reducing grip in corners on the front wheels and producing understeer.If your car has the more favorable set up of negative scrub radius then installing a wheel spacer can cause bigger issues. The outward movement of the wheel can make a negative scrub radius become zero. This is the worst position for it to be in. A zero scrub radius can cause squirm. This is where a scrubbing action occurs on both front tyres in opposite directions which can create unpredictable handling in corners and can lead to understeer too. Secondly, installing wheel spacers on a car increases the leverage on the wheel bearing. The larger the spacer, the larger the leverage becomes. This reduces the life of the wheel bearing as they are not made to take leverage forces and can therefore wear faster, increasing rolling resistance and power loss of the car. Finally, the wheel spacer moves the wheel further away from the damper mounting point. This means that the wheel will have a larger effect upon the damper and will act upon it with more leverage. This effectively makes the spring and damper softer and less effective on the wheel. This means that the car can roll more on corner entry and exit and feel generally softer out on track or on the road.”

Hey my friend on this one I’m iffy, the reason being as I’m still under warranty so before I do anything I ask my local Porsche Tech on there Opinion He explained by adding a spacer it changes slightly the center of how the wheel barring rides in its race Thus causing improper wear. Also his concerns was on the Active Rear Wheel Steering system could improperly wear. And lead to ultimately failure Sense I’m not an Engineer I heeded his advice. Ps: When jacking up the car don’t forget the jack pad adapters I’ve forgot and disfigured the jack point.

Hahaha. True!

[@toddatstone_city_outlaw8714]

Definitely money well spent . I have always felt its the little custom items that really sets you apart from others.

[@AutoAmateur]

Thanks mate!

[@geertverhoeven7615]

I noticed you framed your steering wheel emblem: very distinguished way to deal with a minor failure...and it looks extremely good too. It's like art.

[@AutoAmateur]

Hahaha. Thanks Geert! It’s a reminder to myself. Patience. 😆🤔🤩

[@713vinh]

I think the wheel spacers make it look great on your car. I also love those wheels, it looks great on your car. Nice job mate, it's always fun to see your videos and looking forward to the next.

[@AutoAmateur]

Cheers Vincent! Appreciate it!

[@garydilbeck8882]

EMBLEM UPDATE!! As I said before I have been struggling with commitment on color scheme. It turns out that I happen to work with someone who has a side business making decals and such. For a small fee he can make me any color combo I request. YES! I can “test” my ideas without commitment and the beauty part is I end up with high quality Porsche emblem decals. Still don’t know how I am going to do the real deal but I first have to commit. Trust me! The EMBLEM lives on. Thanks again for gifting it me.

[@AutoAmateur]

Hahaha. You’re very welcome. Now get it sorted and send me photos!! 😆👍

[@Eatongee]

Funny you should post this video now. I am making a list of parts I am going to buy for a spring 997.2 upgrade. Wheel spacers when on the list this morning.

[@AutoAmateur]

Haha. Awesome!

[@ichibawa1]

Hi, James!!! Small observation. Read somewhere that torquing should be done with the wheel off the ground. The is to reduce the chances of vibrations happening.

[@AutoAmateur]

Thanks! I have never heard of that before. Interesting! I'll look into it. Cheers!

[@edyb2653]

“I knew there was someone else... wait: Nick Murray!” 😂 lol. Happy New Year James & family! Cheers, Irwin

[@ChildrenofLDN]

Hmmmmmmm! Spacers. 991 coming next week...I think I might be ordering some spacers. Cheers!

[@AutoAmateur]

They’re a must for me!! They really finish off the look of the car well.

[@garydilbeck8882]

My 997’s build sheet also listed spacers... none???? Hmm! I figured someone had removed them along the way. None the less, there will be replacements. Looking forward to upcoming content. Take care James.

Thanks Gary! Cheers!!

Suggest you put a thin layer of grease or anti-seize on that spacer, esp. if it’s aluminum.

Hi James, which spacers would you recommend for a 991.1 C4S, front and rear? Many thanks!

[@AutoAmateur]

You could do 5mm front and 7mm rear but personally I love how 7mm front and 15mm rear looks.

[@bobbygfl]

[@PeteinMD]

I'd be afraid that, with the wheel further out, you might begin to sand the rear fender a bit... just my uneducated guess... :)

[@flipperdave2571]

The spacers look great! The question i have would be, Is there more "road dirt" that kicks up on to the body since the wheels are slightly outside the fender wells?? Thx!

[@AutoAmateur]

That’s a great question and I would say yes, a little more. I certainly noticed a slight increase in crud on the side of my 997. I’m expecting the same with my 991.

[@chris-eccohealthcare]

Hi James, I have the 991.1 s, do they give any better performance or is it more aesthetic? Also do you loose the locking wheel nut ?

[@AutoAmateur]

Hey! Anecdotally I’ve heard they can make your drive feel more grounded, like they could help with handling. I don’t know if this is true or not though. You need longer bolts, so yes, you would lose your locking wheel nut unless you can get a longer one from Porsche.

[@dannykl6883]

Any thoughts on lowering springs? I thought about doing mine but my mechanic talked me out of it he said it would make the ride too hard ... Great vids btw, keep it up! 😎👌

[@AutoAmateur]

Thanks Danny! I’ve never really been a fan of lowered 911s. They look good but I’ve heard the same about the ride quality. Plus here in the winter with the snow I need every bit of clearance I can get. 😆👍

[@jkaput67]

Spacer looks good, maybe it needs a drop now? Are you considering it?

[@AutoAmateur]

Yes and no. I like how it would look but with the snow and ice here I need all the ground clearance I can get. 🙃

[@jamar959]

Noticed you don't use any protection on the jack. Easy solution - use a hockey puck.

[@AutoAmateur]

Good one! I did use a hockey puck actually. I must have left that but out of the video footage. It’s a great a simple solution right? Cheers! 🤩🙌

Hi James, Thank you for doing this videos, they keep us informed and entertained! I have a question regarding 991.2 C2 rear wheels (ET 76). Can I go and install 991.2 C4 rear wheels (ET 56)? Front wheels specs are the same in both C2 and C4. Thank you for your thoughts in advance! Martin

[@AutoAmateur]

Hey Martin! Yes, you should be fine. The only thing you need to consider is that the C4 is the wide body and C2 is the narrow body. I believe the rear wheels in the 991.2 C4 are an inch wider than the front wheels, in which case they will sit wider on your 991.2 C2. Having said that, I have the same thing going on with my 991.2 C2 (which is a narrow body) and the RS Syder wheels I just installed on them have the same inch wider rears. They fill the wheel arch perfectly and look pretty awesome / meaty on my car. I love them.

[@davidhohner71]

Awesome video. Have enjoyed your posts. I drive a 2004 996 for ten years and would like to up grade newer. Any suggestions. I live near Toronto Canada so there is lots to choose from. Cost is a huge factor as I am now retired. Thanks

[@AutoAmateur]

Hi David! Thanks so much! Appreciate the feedback. If cost is a significant factor but you’re looking for something newer with some upgrades, I would seriously consider the 997.1 from 2006 to 2007/8. You can find some great mid-range mileage C2 and C4, even the S models for extremely reasonable prices. Shoot me a line at [e-mail] if you want to talk more!

[@All993]

Why didn’t you use the other two (2) screws to hold the spacer in place (and flush)?

[@AutoAmateur]

The rotor only has two screw holes. One to keep the rotor to the hub, the other to be used for the spacer (or just another screw for the rotor).

[@johnhume5880]

Not spacer related but rather how do you clean out the snow and salt that falls through the open spaces in your garage flooring?

[@AutoAmateur]

Hey John! Great question! It’s pretty easy. Every now and again I’ll go over the floor with my shop vac. Gets it all up straight away.

[@korrossion9120]

Hello James, great videos and info! I'm looking at buying my first Porsche and decided to buy a 991.1. Any advice on how much is a fair price for 2013 or 2014 CPO one? How many miles under is still a good buy?

[@AutoAmateur]

Thanks so much! Hit me up at [e-mail] and we’ll talk!

[@D.vanlente]

Perfect! Do you have PASM?

[@AutoAmateur]

No. One of the few gadgets I didn’t get with my build.

[@danielt.3152]

Isn’t there some risk the body can bump into the tires on uneven roads?

[@AutoAmateur]

Great question! If I had wider spacers, yes I believe so. Especially if my car was lowered. Right now though the tires are still just slightly inside the outside line of the wheel arches, so any major bumps are still going to miss the body.

[@danielt.3152]

One last quick question where did you get the scratch free socket for the lug bolts and the size?

[@AutoAmateur]

Sure thing! The 991 needs a 19mm socket. Here's the one I have: www.amazon.com/Titan-Tools-21092-Non-Marring-Socket/dp/B008XM7MJ4/ref=sr_1_10?dchild=1&keywords=19mm+socket&qid=1602684319&s=automotive&sr=1-10

[@marksgametime]

Hey man, im a fan & subscriber to ur youtube channel. I recently installed the wheels spacers just like what u did. I followed the torque 160NM / 118 ftlb as instructed but im experiencing vibration of the chassis and wheels at speed 150 kmh & above. Any advise.? Thanks

[@donnachelsea7663]

I have a 991.1 2013 same color and I want to put the spacers does it affect the way the car drives I heard that it would ruin the tires and the way it takes turns is this true

[@bargemail2]

With all your new found winter driving, no anti seize compound?

[@AutoAmateur]

That’s a great idea!! You’re right. I’ll do that tomorrow. Nice one!

[@bargemail2]

Auto Amateur Wear your gloves, it’s nasty stuff!

[@bargemail2]

I would put a dab on the spacer holder screw, a bit between the hub and spacer, between the spacer and the wheel, and a tiny amount on the start of the lug nuts.

[@lunarmicro]

Any idea to increase 991 ground clearance heigh? To add 20-30 mm more

[@AutoAmateur]

I’ve never been asked that question before! Most people want to reduce the ride height of their 911s. I really don’t I’m afraid! I’ll have to research that now because I’m curious.
