R32 Gtr Coilovers Into 2Wd Gtst With Rb25Det &gearbox Fitted With A Gtr Rear End.

[THENIG]

Ok I have sifted through 30+ pages of results in the suspension section & haven't found my exact answer yet.

Bought a set of Bilstein shocks with unknown springs in a pretty sorry state for $100 which are for an R32 GTR. My intention was of rebuilding/re-valving and buying a new set of springs for and fitting to my sedan.

I need the rears with the 'yoke' thing at the end so they can be used with the GTR alloy uprights that are fitted to my car. Apparently their isn't much difference in weight at the rear between Gtst & GTR so I'd be guessing the valving of shocks & spring rates would be similar.

I know that GTR's are a bucket load heavier than standard GTSt (200kg?) so the front valving in the shocks and springs will be unsuitable, but are they physically the same dimensions as the Gtst shocks?

If I take them to get rebuilt /re-valved will they even be the right length or should I just bin them & buy two new ones specifically for a Gtst?

Also if I do buy new ones for a Gtst will the extra weight of the RB25DET engine & gearbox combo over the front wheels warrant getting different spring rates or re-valving of the 'off the shelf' Gtst items?

The secondhand Bilsteins that I bought don't have the slots for the adjustable cir-clip but the chromed shafts are all in good condition, the bump stops & dust covers were rubbish, as were the springs. I got the local pedders to remove the springs for me and test/inspect the shocks.

They were deemed to be good condition for my intended purpose.

Car has seem the track and I intend to be back once suspension is sorted, but I still would like it to be compliant on the road so I can consider using it as daily transport and not be tempted to sell the thing because I have no use for a car that comes out four times a year & can't be driven on the road.

Car also has whiteline adjustable sway-bar at the front (27mm dia.?), adjustable castor rods and upper camber links. Rear only has impul non adjustable sway-bar and rest standard GTR.

Am I wasting my money rebuilding them or throwing away money buying new ones that will give me the same results?

Any productive advice would be appreciated.

Cheers

use the rears and revalve to gtst spec

from memory the gtr/gts4 uses a slightly shorter front but if you are getting circlip grooves added you might get away with it. If someone confirms they aren't good then worst case get new gtst fronts.

You can get extra grooves machined in your current shocks to suit the circlip adjustment.

It's cheaper to revalve than buy new so your train of thought is sound provided the ones you have are ok to begin with.

Thanks for the reply Dave, good idea about getting grooves machined in the fronts to match Gtst length.

I am pretty confident that they are all in good enough nick to be rebuilt, at least I have a bit more confidence that I am on the right track.
