wsup evry1, im a new user, but i been reading the forums for months since i got my dsm. Now a an opportunity to post has actually come up. I got a 96 RS and i just got eibach sportlines and put them in myself. I think i did a acceptable job. evrything looks arite, a little bouncy , but handlings arite. the problem i gotis this weerd vibrating of the chassis, in all gears. and its like a quick vibration and its alot more noticeable wen u giv the car mor throttle wen driving.. i really dont kno wut it is..ive been told motor mounts so far and a broken ass rim, cuz my front right rim inside is cracked. But yea. thas the problem, and i kno thers hundreds of ppl here who kno exaacly wut theyr talking about wen it comes to the 420a(and its suspension).. so help would be really helpful.. thnx

PS: just springs, no shocks and i trimmed bumpstops like instruciton say.. and i followed haynes manual bes i could.

The first few things you should check is your lug nuts, make sure they are tightened down. Are the rims balanced correctly? Also could be because the car could be out of alignment real bad. I'm gonna guess thoguh and say you probably didnt do a good job tightening your lug nuts

I think I just got dumber reading that post.

Whatchooo talkin bout mang!

.: Scratches Head :. I didn't shorten my bump stops... Why is that needed?


Peace,

So the strut doesnt bottom out. When you lower your car there is less travel on the strut shaft. If you cut the bump stop like a half inch you give the strut an extra inch of travel for rebound. Don't want your strut hitting the bumpstop everytime you hit a bump if your slammed low. Know what I mean?

Yeah, On mine I cut the front bumpstops in half and left the rear bumpstops untouched. It rides so much bettah.

ok..lolguess ppl found out somthing new..well.im still ridin around wit that gay vibration, i feel like power is being lost and it will wiggle the car apart if i push down the pedal all in.. il chek lug nuts wen like u guys said, first thing.. then im not sure wut...

The first step in getting help for your problem is being able to produce a legible post. I stopped reading your post when I saw that your first two words didn't resemble anything in the english language.
