Eibach installed but!!

[alkuku]

well I bought Eibach springs from tirerack.com
part# 38137.140 and installed it
the dropping excellent and the stability is fantastic
but I noticed the back of the car is jumping a lot
like a cheap spring !!!!
did any one noticed this thing or its just
me or its normal or its a factory issue
I'm thinking to replace it to H&R
I heard its more better than Eibach
note that I have 20" rear wheels with
285\30\20 nitto invo ;)
front 255\35\20 dunlop maxx sp
can some one give me good advised
I don't want to lose my nitto :(

I did not notice this ,but I also swapped out the stock shocks at the same time.

I think Mojave is on the right trail, any/all springs when swapped with aftermarket shocks/struts will perform better than just lowering springs alone with stock suspension.

The G8 stock shocks weren't made with lowering, and the new spring tension in mind.

Is this with load, or no load at all?

Mine is perfect, I've had mine for over 7 months. No issues you are describing. I didn't change struts or anything. I love the ride and it actually doesn't wheel hop as bad as it did before. I also plan to buy the bmr control arms which should stop most any wheel hop
when getting on it from a dead stop.

Mine have been on for a little while but I don't have a bounce

[MojaveG8]

Another thought is your 20" tires. Have you checked clearance?

[MtbDoc]

My GTO did NOT do well with its first set of lowering springs; better with the second; now I'm swapping to coilovers. And the G8 is going straight to the coilovers.

[G8Smitty]

I have the Eibachs with the stock dampeners and I have no bounce. I have 18" rims, which probably softens the ride a little. I have also never had my car wheel hop (275's on the rear).

What wheel size/offsets are you guys running?? just curious if there is any rubbing going on.

[locrzn#92]

19x9.5 w/45mm offset. No rubby dubby
