Figured I would start a thread on the subject for my type I SB
I came across a 944 guy that mentioned the Koni universal coilover.
I believe he spec'd it out at:
$184.95 each new at Summit with 17.17" extended length and 11.73" collasped length, 5.44" stroke.
Stock 944 is 16.81" max, 11.18" min
I am looking to mate this with my alum 944 late arms. These arm don't have the provision for bump stops that the ealry alum arms have.
This bug is being built for track, but with a limited budget. Therefore I would no like to go the remmele route, or kersher. Also some of the 944 stuff is to darn expensive.
The Koni's have height adjustability and a limited range of valving to chose from. I believe they are adjustable only for rebound, but I am not 100% sure.
If anyone has any specs on Beetle IRS coilovers, mush appreicated.
Would like to determine if this is a viable option
Part # at summit KON-802650SPA1

Looking for ideas on koni universal rear coilovers

Double check that part number. The product it brought up has different specs that what you stated.
I would be very suspicious of this shock as they list it for a drag application. Does it have 90-10 valving? You'll be buying the springs seperately. Add to the cost, but you get flexability with that. Are you going with coil-overs to avoid changing your torsions?Coil-Over Shock Type: Double-adjustable

Adjustable Valving: Yes
Extended Length (in): 15.710 in.
Collapsed Length (in): 10.630 in.

Body Diameter (in): 1.690 in.
Bushing Material: Rubber
Bushing Color: Black
Coil-Over Springs Included: No
Recommended Spring Diameter (in): 2.500 in.
Adjustable Mounting Bracket Included: No
Hardware Included: Yes

Ozzie,
I may have selected the wrong part # from summit... I was at work, with the boss doing his rounds..
But in you pointing that out I was able to down load their catalog and it did list it as a drag only.. thanks for pointing that out.. it does not have 10/90 valving like in the past according to koni..
Struts also go by KONI ADJUSTABLE DRAG RACING SHOCK ABSORBERS SERIES SPA1
If anyone is familiar with another option, please chime in. Yes, to avoid torsion bar.

I've decided that QA1 has my shock of choice. http://www.carrerashocks.com/
Their 'Proma star' shock has good adjustability range and is pretty cost effective. (google the part number of your shock of choice to find best prices)
But I would think hard about getting rid of the torsion bars. We've been planning on running this car as a coil-over car since the start of the project. The front is fairly straight forward. The rear however, poses a little more of a problem. The problem is space. If you use the most commonly available spring size, 2.500" I.D., they will come in contact with the C.V. joint boot. That leads to a pretty quick failure of the boot. There IS a streamlined boot used in Formula ford and similar type cars, but they are hard to find. Another option is to use a smaller 1-7/8" I.D. spring. They are available, but not many people use them. That means, if you're trying a few different springs to find an optimum rate, you probably won't be able to borrow some from local racers. So you'd have to buy every one you want to try.
Neither issue is too hard to overcome. It just takes a little more time and money to sort out. I'm going to get the coil-over shocks I had planned on getting, but I'm just going to stay with torsion bars in the rear for the foreseable future.
