I have a 99 Civic Si with Tein HA coilovers. The ride is horrible. They oscillate (read: BOUNCE) at any stiffness setting but the stiffest setting. My car is about 1.5" lower than stock ride height. They seem to not want to compress as easily as they rebound. I'm pretty upset about the ride quality. When I try and accelerate on the freeway I can't even maintain steady pedal control... Does anyone have any experience with HA's and can help me? Thanks so much!

 

Wow I am really sorry to hear about that, I thought that Tein made some bad *** ****. Are you completely positive you installed the springs the right way

 

It sounds like your shocks might be blown. Here's a test: stand outside your car and push hard down on one corner. If, when you let go, the car rebounds up and down and up and down... your shock is gone. Try this for all four corners.

 

thats why some pple dont need that ****. they're like 30 way adjustable ....they're just not adjusted right. not for the daily driver/more for a racer who adjusts that **** daily for a few months till its jsut right....then adjusts for specific tracks and conditions... might want to see if you can get a proshop to adjust them for you. you could trade them to me for my GC/koni setup. very very smoof. ill scrounge up a few bills to go along with em if you want to trade. everything is top notch. im in florida.

 

I already did the push test as well as inspected the shocks for leaking fluid. The rear has more secondary rebound than it should, although there is no visual proof that the shock is gone. WTF.

 

how old is the set? if it's new, see if you can have them replaced. A shock can blow without necessarily leaking fluid out of the shock body. The internal valving may have just failed. If they're old.. umm.. you might be s.o.l. see if you can get Dusty to swap them for that set of GCs/Konis (if they're yellows)!! ;p~
