They are universal. Not designed for a particular car.

Order them by part number from Summit, Jegs, etc.

Or buy the entire Spec944 matched Koni front and rear setup from Ground-Control which can include adjustable camber plates and an integrated strut tower brace.

I have looked on both of those websites and they both have told me they are discontinued?

Do you have a link? And will the kit I posted not work?

Looks like they changed the part numbers. That's annoying!

Looks like DD501 (Bearing) and DD502 (polyurethane) are the new versions.

One has a solid bearing mount, the other uses a Polyurethane mount.

Would it hurt to use the poly mounted shock? Or is there something special about the bearing style? Sorry for all the questions like I said I just bought my car.

Another question what coils would work with that shock for the rear?

The bearing is solid mount, the poly introduces some additional spring rate into the solution.

I'd go with the bearing mount on a pure race car. It will be noisy and the bearing will wear out and need to be replaced every so often. Same with the adjustable camber plates for the front end.

For a street car that is raced occasionally, then the polyurethane ones might be a better compromise.

I'd not use coil springs In the rear and up the size of the torsion bars and keep the center of gravity lower. Just my opinion.

I'll let the more experienced folks talk spring rate though as there is a lot of theory behind it that ultimately requires data on your car (corner weights) and driving style to start to choose them.

You could also go with Ground-Control's solution:

http://www.ground-control-store.com/products/category.php/CA=218

And ask them about spring rates and shock valving.

I'm really wanting could all around due to the adjustability of them.

So this brings me to my previous question. Could I just use this kit? Or is the front suspension so different it won't work?

Does anyone know what the Bilstein V36.0059 strut was replaced with?

Leave em. Replace with 26 or 28's and enjoy a slightly lower CoG.

If you still need more spring rate, add coil springs to the shocks, but you'll not need as much spring rate

To properly delete them requires special bushings from elephant racing.

Fiat 2 Turbo's Bilsteins are about $400 each. They also make a B8 model for lowered suspensions for a 1980 VW Golf/Rabbit #34-184530 that is revalveable and only cost $140 on Amazon right now. Any comments on them?

Apparently the B8's are valved the same as the normal HD's available which are B6's. The are cut off 15mm shorter.

The main PITA is that these are 1/2" rod end mounted, not 12mm (as our stock shocks are). What we've done on our racecars (I'm actually running Bilsteins in the back, but same mounting) is to drill out the mounting spots to 1/2" and use 1/2" Grade 8 bolts. This requires a heavy-duty drill up top, as you're milling through a long bushing; it will eat any puny cordless drill.

You also have to make up spacers to locate the shocks centered in the mounting spot; the 1/2" rod ends are much narrower than the bushings on a stock shock. So what is the easiest is to get 1/2" ID pipe or tubing, and cut lengths as needed to fill the gap.

Alternately, if you have access to a machine shop and the time and inclination, you can have the shop machine spacers that will fill the gap and also allow you to use the original 12mm shock bolts.


Just to clarify, what spacer can be made to allow the 12mm bolts to still be used? If a sleeve was made to slide over the 12mm bolt to "take up the slack" from the 1/2" hole in the shocks wouldnt it have a very thin wall (0.375mm wall thickness)?

I am thinking about buying the rear coilovers but dont want to drill out the stock mounting holes for the rear shocks
