QA1 rear coilovers for IRS steel arms

[Sandeep]

Thanks for the information.

I'll look at my options and post back the outcome here.

Sandeep,

Here is another fellow, who gave me the idea to use the same QA-1 coilovers, not sure you have seen his post on Rennlist.

Very similiar, but gives more detail in some areas, that may not be apparent on the first link. He did not have a good way to attach the top of the coilover.

Enjoy, hope its useful to you.

I've got the QA1's to fit upside down by drilling a new lower cup mounting hole, higher than the original hole. Make sure you check that the shock does not bottom out before you drill.

I'm now using the DDR4855P model, but still deciding on the spring rate before ordering the springs.





Still need to pick up the correct length lower mounting bolts.

300# will be pretty damn close based on Clive's calculation, depending on rear axle weight you might go as high as 350-375

Hi Sandeep,
Why not junk the bump stop on the trailing arm and fit one on the damper? That'll have two effects:
1) The bump stop then relates specifically to the damper as it should without relying on a remote location and possible miscalculation (and zip ties!).
2) The bump stop would act as a cleaner/scrapper on the damper rod adding to the cleaning seals and minimising the possibility of ingesting dirt.
QA should be able to recommend some bumpstops.

For bumpstops go with the vw/audi marshmellow bumpstops. they are a favorite of racers because of their progressive nature. You can trip them down as needed.
