rear coilovers

[ricola]

Obviously depends on what coil-overs as they come in different sizes, externally 944 and type 1 steel trailing arms are the same (I've actually got the type 1 arms on my bug with coil-overs)

anybody have information abaout the coilovers from red9design?

If you are going to fit uniballs with coilovers then you must fit IMO a full 5 bar Kafer Cup Brace as the standard damper top mount is not designed to accept the full suspension loads that a uniball/coilover installation will impart.

I won't open the debate on the red9 designs.......................

Hi,

i want to use only the coilovers without the uniball system.

Any helpfull information about the spax coilovers?

If you don't want the uniball suspension then I assume you will still retain the torsion bars? In which case you will need to decide what spring rate you are going to use on the coilovers. It would not surprise me that you will only need a very light sping, if any at all.
The cause of concern with rear coilovers is that the top mount has not been designed to accept a spring load it being just a 12mm cantilever long bolt on the end of a forged arm that is weak in the lateral direction, hence the suggestion to use a Cup brace. However, I would guess that light loads say 50-100lb/in would not stress the fixing too much.
Why do you want to fit a rear coilover?

I will use a special bearing from GWD (Gerd Weiser)

so i can remove the torsion bars

Cupbrace (three point) is already installed

red9design uses a 275lb/in spring on their own car

Dont know how to calculate lb/in in newtonmeter

Kerscher uses 120-140 nm spring without torsion bars aand three point cup brace
