Coilover Issues
Hi everyone, so I just recently just got full up version T-Demand prodamper coils w/ slide upper mounts front and rear, 40/45k(f) 40/28k(r) spec pistons in the shocks, pillow lower mounts, and pro bearing sheets. And after installing them I notice they make a loud rattling sound when I drive slow or on rough roads. Can someone please help me out.

Can you be more specific? Have you looked for the origin of the sound? Have someone listen from outside the vehicle as you try to recreate it. These cars are hard to identify noises in because they are well insulated, and at this age it could be literally anything. Especially with such stiff spring rates.

@firelizard Yes it can be heard from outside from the only the rears. But when I driving on main roads or on freeway the noise goes away. It's mainly when I go slow through neighborhoods it seems to make the noise.

The top piston shaft nut on the plate bearing may need to be tightened, these will commonly make a rattle at low speed bumps if not torqued enough. You likely can't tighten it enough with a ratchet because the piston will spin. It may need some quick hits with a good impact.

Hello Thomas, please double check and make sure everything is tightened properly and also if the SP13 upper plates are adjusted to the max setting it is possible the nut is making contact with the body and will need to be adjusted slightly, or the allen bolts on the SP13 plates could be loose please check those as well. You may also want to check the rear arms and see if any of the bushings are worn or damaged. If you have any questions or concerns about our products please feel free to give me a call at the shop or stop by.
Thanks, Sam
