These videos are worth their weight in gold :) I went with coil overs AND kept the torsion bar. I remember that mounting point wasn't ever going to be quite right to support what was asked from it. That's about all I remember and I appreciate your expertise. These Porsche's are finally being appreciated.

Great explanation. I have been reading books and web pages but there is nothing like a clear video and a clear explanation to demystify how something works. Working on Classic Porsche vehicles takes a bit of learning, but I am enjoying it and I'm amazed at how much I learn on a day to day basis. To all of the people who make KZbin videos, thank you.

I'll tell you something interesting about the front suspension; the lower control arm is designed to yield under impact to keep from damaging the main structure of the car. If you slide into a curb, it will sacrifice itself and protect its attachment points to the chassis. I changed more than few of them in the 80s and was always impressed that the damage remained isolated to just the control arm. I slid into a curb in my 2nd-gen Camaro once and managed to bend the lower ball joint, spindle, and sub-frame. The lower control arm was fine, though. It's like the GM engineers were only looking at the issues in front of them when they designed the front suspension. Obviously the engineers at Porsche (or Audi?) were looking further than just what was in front of them.

This is true for the old stainless steel wishbones on the 944 - I've been there done that on a -83 model, and they bend at deformation points, but I've been told that it's very different when it happens with the newer aluminium alloy ones that shatter/break off on impact. Some of the people I know that use 944's on the track, prefer the old ones(sometimes a little modified) or other custom stainless for this reason, and the fact that they're lighter (!) though everyone(most people I talked to anyways) thinks it's the other way around. The alu ones feel a little tighter if you really work them, though. kzbin.info/www/bejne/bGXKZ4Kdj8aIodU

Great explanation. I heard some classes have to have the torsion bars by rule, but that some people somehow disconnect them. In other words, they leave them there because of the rule book, but they are really using the coil-overs on the back to make it easy to corner balance, change spring rate, etc. I guess they shave the splines on the torsion bars???

Very cool video that explains everything in a very good and simple way! One question regarding coilovers, as we are putting a set on my wife's 944 Turbo (1986) from Gaz Shocks in UK. They advised to keep the torsion bars (to my surprise) so I'm wondering if the mounting points need reinforcing to support the coilovers setup without torsion bars or if it's mostly a question of hardware (better grade bolts). Our car is stripped and will be caged and welded everywhere too. Thx

Most people use the Racer's Edge lower shock mount bolt. Of course, keeping torsion bars will reduce the load on that bolt. I personally like the torsion bar/coil over combo, but it takes some time to index the torsion bars to get the spring rates and ride height correct. Otherwise you can have the two different springs working against each other in parts of the suspension travel, which will cause odd handling.

We didn't measure anything before removing it as we're changing the ride height anyway, and the old shocks were completely blown :(. Rule of thumb is to have no tension on the bar when the wheel doesn't touch the ground I presume, so you don't have the coilover or the bar working against each other at any position during wheel travel/

@@yotah1TheModernRacer Well, up in the air, the control arms actually droop down and are twisting the torsion bars the other way. I've ground down the crimp so I can remove that torsion bar cap on the spring plate and welded a little tab onto the end of the torsion bar. This way, I can raise the control arm to the "neutral point" and the torsion bar will slide right out (because there's no twist on it). You want your shock spring perch to also just make contact at this neutral point. Then, let's say your ride height is 1/2" too high, jack the car up, find that neutral point for the control arm, slide the torsion bar out, raise the control arm exactly 1/2", reindex the torsion bar so it slides in, adjust your spring perch so it just makes contact, and now you've properly reset the ride height.

No, I don't. But, in the race cars, I've modified them so I can quickly slide the torsion bars out through a hole in the rocker panel. Makes it really easy to do - just jack up the control arm a little bit to take the twisting pressure off the torsion bar, slide it out a little way, raise or lower the control arm a little bit, then rotate the torsion bar until the splines slide back in to position.

Wow, I love how Porsche added all of these adjustments from the factory. A real drivers car, I definitely could nerd out on a vehicle like this. There is a guy where I live selling his 84 and I'm considering trading my Toyota truck for it. He has a very detailed history of the maintenance and the car only has 86,0000 mi. On it. I am a little apprehensive though because I have been told these cars are sensitive and parts are high. I do most work on all my vehicles so I could cover maintenance easy, I just don't want to buy something that is going to be failing all the time. Are these cars reliable if properly taken care of?

+Josh Smitty Yes, I think these cars are very reliable when maintained well. (I've had at least 1, and sometimes several, 944s for the last 19 years.) For a car with under 100k miles, you're looking at a clutch job soon (if it hasn't been done already). Parts are more expensive - that's cost of ownership to have a Porsche. If you can do your own work, I think you'll find it rewarding to own.

Ok, I'm trying to decide weather to remove my torsion bars, or re-index them and leave them in as it came from the factory. Here are some pros and cons of removing the torsions bars if I end up fully prepping the car to move from DEs to racing. Pros: Ease of ride height adjustment and changing spring rates. A tiny bit of weight savings. No more messing with torsion bars. Cons: I'll be put in a faster group, which is totally fair. Car was not originally design to bear the weight at the shock. What I refuse to do is modify the bars….

If you choose the right torsion bars, and take the time to index them, they are just as good as coil over springs. It's also a cheaper choice than getting coil over shocks, with solid bushings, and new lower mounting bolts, just to run a coil over spring.

Van Svenson you are right about it being cheaper; problem is I already installed a real nice set of coil overs :( Now I want to try adjusting the ride height by re-indexing the torsion bars, or, just pull them out and run in group 10 (instead of 8) with SVRA, or a different class in PCA (not familiar with PCA classes etc.) but I'm sure PCA will rightfully make me run in a higher class than people with torsion bars. This is exactly the set I installed on the car: www.lindseyracing.com/LR/Porsche/944SUSESCORT/LRK-944-BIL-SUS-02CP.html I just want to have fun, so because I'm not that mechanically gifted, I wanted something I can adjust as "easy" as possible.

RaudelandAbby It's a shame that deleting the torsion bars bumps the class up... Unless you're going with a spring rate that's higher than you can get in t-bars, there's no performance upgrade. For PCA, SP1 class must have the torsion bars and SP2 allows you to remove them.

At this point I'm spending money on DE's that perhaps I can use towards a racing license; don't get me wrong, DE's are awesome and the entry point for an average joe like me to drive on our dream tracks, but will eventually need to go for the racing license. As far as the torsion bars, I'm a mess with that decision, on one side I'm somewhat of a purist (growing up in Cuba seen old original cars might have done that), but on the other side I don't mind a little bit of resto-mod. Still, I want to comply with the intent of the rules, and have the car look as original as possible.

I've been reading on Elephant Racing about their "quick change" torsion bars and spring plates (www.elephantracing.com/suspension/springplate/944quickchangespringplate.htm), but, if you take the torsion bar out with the car loaded / or on the ground per se, wouldn't the car come down and all the weight would go to the shock? If ride height is adjusted through the torsion bar, I would think the car would come down when changing the torsion bars with their "5 minute torsion bar swap per side".

Elephant Racing is a great company, and I've used several of their products over the years. But, that spring plate is just a $400 version of my taking an angle grinder to the end-caps! You're right, that "adjustment" screw they have is just a replacement for the eccentric, and should be used for corner balancing and/or minor ride height adjustments. To adjust the torsion bars, I put the car on the lift (or you could do it on jack stands) and then I raise up the control arm with a support post (or you could use a floor jack) until I get to the point that I can simply slide out the torsion bar because there is no "twist" in it. Once the splines are disengaged, I then raise or lower my support post by how much I want to change ride height (e.g. raise the control arm 1/2" to lower the ride height by 1/2"). Then I rotate the torsion bar until the splines line up and it slides back in!

But what exactly do you mean with cornering balancing of the rear? I've used those two so called ride height adjustment bolts to lower the rear by about 2 cm, because I use 968 CS springs up front. So to balance it out, I had to lower the rear as well. So I use the method with those two bolts. But you're saying that changing the splines in the torsion bar, is better. Why exactly? I've lowered it with success I must say, I don't experience anything weird while driving. What is exactly this cornering balancing and pre-load what you're talking about? Also it's just so much work to take out the whole rear axle off, just to lower the ride height. So I used the other method which is much easier... But now I hear it was not the best method. I am confused. Even the workshop manual says those two bolts are for ride height adjustment. They did not mention anything about that pre-load and corner balancing what you were talking about.

I explain corner balancing pretty well in this video: 944 corner balance and alignment But the short answer is: picture the two diagonals of the car - front-left to rear-right and front-right to rear-left. This is what supports the weight of the car. If one of the diagonals is supporting more (or less) than 50% of the weight, you get a "see-saw" effect when you transfer weight from side-to-side while you corner. If your corner balance is off, the car will handle differently in right-hand vs left-hand turns - which, if you road race, is bad. If you oval race (think NASCAR) it can actually be a good thing. If you have a street car, it won't be as noticeable. To change the corner balance, you have to move a wheel up or down relative to the chassis of the car. If you have a strut with an adjustable perch at the front, this is the easiest method - you just change the height of that perch. In a stock 944 (non M030) the only method you have is by those rear slip plates. If you move the rear-right wheel up (lower the ride height), the other rear wheel, and the front-right, will be carrying more of the car's weight. If you move both rears the same, it will probably remain pretty close. But, if you really want to know, get it corner balanced and see!

Van Svenson Thanks a lot for the explanation. I use my 944 S '88 as a road car mainly. But I do a lot of spirited drives though. So let's just say I drive it in a "sporty" way. Anyway, when was adjusting the rear height, I pulled out and cleaned those eccentric height adjusting bolts, I marked a line on them exactly at the same spot, on both of them. So that when I adjust the height, I could have these marked lines at exactly the same angle, thus having the ride height at the rear at exactly the same height. I also checked the space between the fenders and the top of the tyre from front to rear and also the height of the car relative to the ground, right in front the back wheel. This is where they usually take the measurement points when measuring height I suppose. Now when I bought the car, it was at the lowest setting in the rear. Because it had awfully low springs at the front. But even in the lowest setting in the rear, it was still a lot higher than at the front. So I thought 968 CS springs would be the best option, because they're factory springs. And so I was right. It got the front up higher, but not too high and not too low. I only had to adjust the rear accordingly. And I noticed during the first test drive, that the car was more balanced, I felt as if there was more spring movement in the rear, and that it took way less load at the rear. I felt that especially when going over bumps. It felt suppler at the back. Unfortunately for me, I do not have the aperture like you do, for corner weight balancing. And I do the alignment at a garage. They did a pretty good job there, I must say. But they do not have weight measurement systems like you do. I just assumed that having the car at the same height both front and rear would do the trick nicely of having as good as possible weight distribution. But what you're saying in that video which you've linked, is that you can actually change the weight load in the rear of the car by these two height adjustment bolts? But then doesn't that also mean that it works for me as a height adjuster as well?

My 944 cabriolet was in garage storage for some time, and when I pulled it out to wash it, I noticed that the right rear was dropped about 1-2 inches lower than the left. Based on the suspension design, am I looking a replacement of shock, or torsion spring?

Torsion bars usually don't go bad... But shocks do. So I'd start with replacing those.

Thanks. My thought initially also. Weird thing is I jacked it up, let it hang for a few minutes, and it is much closer now left to right, maybe only 1/4 inch difference. It has held this new height for over a month now. Still seems suspicious though, and I'm prepared to repair. If it is shock, that seems like a very easy replacement. Is the shock under load, like a coil set would be? Thanks...

Rob Runkle Yes, the shock is under the torsion bar's load. If the shock is bad, or has some failure that's limiting it's movement, I could certainly see what you're describing.

The proper way is to re-index the torsion bars.

Van Svenson thank you for the reply. But I have no idea how to even begin to do so. How much would the suspension lower the car using the bolt method where I can loosen both and turn the back bolt
@vsvenson
@vsvenson 6 жыл бұрын
That depends on where they bolt currently is in it's adjustment. Maybe you'll get a 1/2"? Maybe a little more or a little less?

Indexing the torsion bar looks like a pain. The factory ride height in the rear of US cars is too high to meet our crash standards, so I'd like to lower mine to the proper height for handling

It is a pain. You can lower it with the eccentric bolts, but usually you only get a half inch or so.

Ok so u removed the torsion bar both side & than you removed the 6 bolts on spring plates, that's it, than u lifted the spring plate to lower the hight of car... Car we lower more than 3 inch by this method.. Thanks

If you lower the car 3 inches, I bet it will just about be riding on the bump stops...
