The car feel very unstable as I hit a dip in the road while driving through a corner. The rear end gets unstable bouncing out of the dip. It gets squirrelly. Has anyone had this issue and what did you do to fix the problem. Alignment is done and within spec beside camber which is -2.5 all the way around.

Bc racing with trd sway bars.

How old/new are they? Do you have the correct preload set? What level of dampening do you have them set to? Was this happening before or after you installed the sways and/or coils? Have you checked the endlinks? Have you checked the sway bar brackets? The control arms? ...honestly, it could be a multitude of things.

Sounds like preload has to be set. When I installed mine, I didn't care if they supposably already had there preload set, I undid all 4, and reset them exactly as should be, and to be honest it seemed as if they were possibly not set tight enough out of the box. I hear people complain about there BC's making this noise that noise, I'll be honest, I don't have ANY of these noises people may be experiencing, make sure you bolts are all tight, and I'd reset that preload if I were you, with an extra 1/4 turn for good luck.

They are fresh rebuilds from bc racing. I installed everything at once. I think I don't have the preload set. How do I go about setting the preload.

check pre load, and also make sure your alignment is set correctly.

Any update?

I end up pulling the motor out the car to do a gte swap and making it a manual. Will update as soon as I get the car rubbing again.

i've got the same problem with my GS on Tein CS
i'll check with a friend tomorrow, if we find it, i'll let you know

the only thing I see is that this is not the good kit
I bought a used kit, and i must have for GS300 on GS430
and the rate spring is not the same

i'll change them asap

There's not a significant enough weight difference between the GS300/400/430 to warrant companies making different coilovers for each model. Also, I've not heard many (if any) complaints about the Tein CS models on our cars, they're generally regarded as a good buy for those who want to be moderately lowered.

I'd say your problem is either with your purchasing of used coilovers that are in need of rebuilding, or that you don't have your preload setup correctly.
