You used those just for the rear correct? Any pictures of the completed setup? Any other modifications needed?

 

I have not completed the retrofit yet. I hsve quite the laundry list of things to do. I have verified that these will work on the rears though. I will snap some pictures to load here.

You do not need spacers for the front at all best i can tell. The front shocks extended are the same length as my H&R front coilover.

 

That's what I've been told, no mods needed for front. This is awesome news!!!

 

What is the thickness of these spacers? And are you eliminating the top mount to run these? From what I have read you need about 1-1.75 inches to make it work. Next question is the adjustability, can you still reach the **** on top?

 

You can still reach the **** for the top adjustment. This is a spacer that will go between my mode upper mount and the body. The spacer i am starting with is 1". The mode mount is pretty thick compared to the other mounta out there. I have another 1/2" i can add in addition or just get one thicker one. The spacers vary depending on lift. As far as what is needed, it depends on desired ride height. And the only metric for ride height is based on cup car subframe measure points that are also not the same in relation to the turbo or GT3 unless you machine subframes to drop the body closer to the frame like the cup. Which i am not.

When i have the suspension fitted, i will take pictures with the spacer and also showing droop. And i will also show pictures comparing shock lengths to my H&R coils. I do not think this is going to be a failure as some think. It will take some tweaking, but i intend on documenting so that anybody else wanting to do this will have all the info to make it work without reinventing the wheel.

 

Here is a picture of the leveling kit spacer on the cup shocks.

 

It was a while back but for some reason I wanna say that in order to have sufficient shock droop at full extension, the spacer will need to be right at 2-2.25" thick especially if you don't end up running 26.8" tall cup rears. Those in and of itself account for 0.7". Also, I would not go softer on the main springs and would stick with the stock H&R 240/260 springs, especially since your keeping the OEM helpers. These shocks have limited travel and are designed for fairly stiff springs on a chassis 600# lighter than our cars. I run 1400/1500 mains which is just a hair stiffer than the 6cup mains and it works very well even on bumpy tracks. Under no circumstance would I run anything less that 1200 or so on these shocks. Good luck with the project. This might be a cheap way for guys to get into a track set up as a lot of these shocks are sitting in shops after being swapped for upgraded triples or quads..

 

Currently the springs 180R/160F. If i were trailering the car to tracks i would run stock cup rates. I am starting here and can go up from this. I consulted a friend who has experience building and tracking cups and RSR and he advised that the stock helper for these springs should work well.

As for the shocks, these have the capability to be adjusted for the rate of springs i am running according to Sachs and have been run at lower rates in other race applications that do not require stock spring rates exclusively. So i should be good with this setup. Obviously we will see.

 

Sweet. Curious to see how it turns out. It's always a bit of a gamble to try to reengineer a single part of a system that Porsche race engineers have spent thousands of hours testing for optimum performance. Looking forward to the results...

 

For sure. Definately a risk.

 

That looks awesome. Are you going to the track any time soon? That will be the real test.

I've got a set I'm going to get if this works out for you.

 

Eventually. Lol. I have a ton of parts piling up. I am doing solid subframe bushings, cup shift cables, monoball everthing, cup spindles, adjustable toe links and camber arms, front sway bar, front differential removal, solid control arm pucks front and rear, clutch, RS LWFW and clutch assist delete. So, the project is fairly big.

 

Here is a comparison of the Sachs GT3cup shocks compared to H&R coilovers. The rears are significantly shorter as suspected. Fronts are almost identical length. Will see what the rears look like with the wheels and subframe.

 

This is about as close as it gets to any real information. Then again, this thread has almost everything you need to know. What other information are you looking for?

Nice to see you back into it VAG. I was always really curious how this would turn out.

 

I've set up a lot of suspensions on these cars and my guess is that the rears will be way too short even with the aluminum spacer you are using. A quick calculation tells me you'd need a spacer about 3" thick to get you where you need. The very limited shock travel /droop may present a handling issue with soft springs and a heavy car. You do not want to run out of travel in the rear as that will present dangerous mid corner snap oversteer. (always make sure you end up with more droop in the rear than the front!). Hope I'm wrong and it all works out without issues. Good luck...
