Hey what up. I just bought a new SILKROAD coilover, it ride great, but the problem is when i go over uneven surface at freeway speed the rear of vehicle bounch left and right, it feel like the rear is very bouncy, i also have rear sway bar and strut bar. If anyone know what is the problem it will be nice let me know THANK YOU

could be the spring rate is either too hard or too soft, or the shock dampening does not match the spring rate...?

btw - didn't know that silkroad made coilovers for a USDM IS300...?

I personally never heard of SILKROAD coilovers. Is it a full coilover (strut, spring assembly) or is it just a ride height adjustable spring/coilover??

If it is the first one, and assuming it has adjustable shock settings, maybe it's set too soft. Or it might be a defective strut and is blown? If it is the second one (ride height adjustable spring/coilover), and your still on your stock shocks, your stock shocks maybe blown.

How long did you have it on the car? Did it do this right after the install, or did it happen after X amount of time/miles?
