[CL9] floaty feel at high speed on coilovers

hey guys

ever since i got my coilovers installed and upgraded from 16's to 17's i've noticed my car seems to float at high speed like on the highway. the back end seems to move and sway alot. car is fine at 60K or less.
I was wondering if i would have to adjust the damper of my coilovers at the back to make them stiffer to recitfy this issue? i got told i needed to 'back my suspension off'.
what is a good setup? i.e slightly softer at the front and full stiff at the rear.
please advise :)

cheers

i think your rear got too much camber on the rear. that's what happened to me when i lowered my CL9 too much without a camber kit.

it felt scary on high speed!

i raised it up a bit, got another alignment and it reduced the swaying effect on the rear.

this is how low it was:

cheers for the reply. yeah i thought it could be that but i've got a camber kit fitted, do you have coilovers?

nice euro btw!

It is not the camber. You have lowered your car so much that it is beyond the damper travel range of the coilovers. Once you raise the cat back up, the car will feel less floaty. I had -3.5° camber and the cat was not floaty when I drive from sydney to melbourne at 110 km/h eventhough it looked worse than the pic above. Mine looked like a V8 supercar in reverse.

Yeah my car isn't that low though. I've been running a two finger gap ever since I got coilovers. Think my coils are stuffed or something..they squeak like mad too. I think it just needs proper damper adjustment. Will get around to fixing this issue eventually. sigh

What coilovers you using?

Was it lowered by adjusting the spring perch? Or was it lowered by shortening damper body through the lower mount?

not sure but you're not supposed to touch the srping perch yes? that could be why..

Yer spring perch is a big no no

i got them installed at pedders so you'd assume they know how to adjust coils LOL

ive got the same coils and mine seem fine and im running on no finger gap/tucking tyre

Yeah the coils are good but i think they may have been adjusted wrong or something :l

whoops forgot to mention that part, most likely they played around with the spring pre load

You could be running like 2kg rear for all you know im not sure how to fix it or ecen find out

Yeah true. It's felt the same on 16's, 17's and 18's

Some coils you adjust using the spring perch (Tein SS) and others you don't at all (Tein Flex and BC N+). And Pedders might or might not know that. Out depends on how familiar the mechanics are. It is a franchise after all.

If its got two nuts where the coil ends im pretty sure you can just have to make sure you dont loosen the nuts from each other.

buddyclub N+ it is a 2 way dampening adjustment coilovers . so maybe they may have adjust the spring perch & stuffed up the spring load.

Yeah most likely scenario :(
