CNC made aluminum Uniball rear suspension system

Where can i buy boots like this? I need it in europe.

hi freaks

so - if i choose DD402 should i use 9 or 10" springs? and fx on autofabcart are:

350 lbs? 400lbs? i have vw1302 and 2028 engine

QA1 told me they only ever offered these with 2.5" springs, though someone posted up that their set was using 2.25" springs. QA1 said I could lathe down the perches (They don't sell a 2.25" set for these shocks) but when I did the math there would be so little meat left on the threaded perch I decided against it. The 300lb springs were used for testing/fitting only, as soon as the engine went in I moved to 550's.

9" springs will be a better choice, or even an 8". I'm using 8" 550lbs out back with my 1302. With the 8" length I can swap out the springs without having to remove the axle or anything else. The 9" springs I have just *barely* pop on without issues. I think if they were stiffer then 300lbs I'd have difficulty for sure.

Yeah, 550's sound about right.

[kendy]

ok, i ordered 550 lbs

[-Alex-]

550 sounds a lot, but i havent tried yet coilovers at back. Mendeola uses most of the time at their rear kit 450lbs springs.





Does it just look like that with aluarms there is more room between coilover and CV joint boot, or is there?

Two things to consider: The kits used in their photographs are for a fiberglass speedster kit which is considerably lighter. Their shock mounting points are changed and thus the leverage ratio is likely different then our (typically) stock mounting points.

With stock shock mounts a 300lb spring will have the suspension sink to 1/2" off the bumpstops with just a body & transmission. No glass, no motor. 550lbs rides well, slightly stiffer then stock, and still requires preload to adjust the ride height with a complete car.

Alu arms are wider in general as you know, but the CV sits even further in the arm, making the shaft itself relatively longer then the increase in track width would suggest. Hence never a clearance problem with the CV boot.

Nice set-up BTW. Who's (german) car is this? I would like to see where he has mounted that sway bar and who's coil-overs thos are.

Don't know that car, i have had that picture few years. I remember that you have aluarms also, what lenght shocks are you using?

I havent yet bought rear shocks, just today got hubs and hats anozied to black, they are awesome. Now sawing for the transaxle.

Yeah, thats why I was interested: I now use 944 shocks (Koni yellow) and they have their (shortenend) bump stop about the same time as my (also shortenend) trailing arm bump stops. Its a good match therefore for my current ride height.
These in the pic seem shorter, more inbound travel possibility, which could be helpfull if you were to go even lower in the rear.
Looks like Remmele coil-overs to me, but not sure..

[kendy]

so..i changed order for 500 lbs

[Wally]

Good info Dave and nice pictures Alex!
Kendy, I think you should probably get used to the idea that a completely modified suspension with coil-overs is just not exactly right the first time and needs adjustments to work as well as you anticipated when you wanted to change from stock.
Buying more then one set of springs is part of that adjustment I think. I ordered an extra set of springs (they don;t cost much btw) two years in a row and I think I have it set now. Sometimes you also need to get used to new springs a little. I changed over back and forth a few times and got a feel for what works best better now.
With a 40/60 weight ditribution (guesstimate) I guess for my car a 600lbs spring theoretically sounds best with my 400lbs front springs, but you never know till you try it. For now, I seem to overpower the 25.5mm rear torsion bars with drag starts. Each application is different is what I am trying to say and multiple sets of springs might just not be avoidable.

Cool, thanks
