So, I've had the KYB AGX's for the GC8 on my WRX for a while now with ground control "coilovers" and eibach springs rated to 250/ 200 and length to lift the car 2"... and since day 1, the rear has been noisy, and the ride has been bouncy ONLY in the REAR.

Anyways, can someone help me find the problem? Is the stock rear top mount the problem??? or do you think the shock has a problem? Or is it something different altogether?! The front is lifted higher than the rear and has NO problems an NO noise, so I doubt the height has anything to do with it.

A little more info... the front can be set on the stiffest setting and make no noise and still have a nice compliant ride over potholes and such. The rear, when set on 1 or 2 (of 8) the ride is decent, but the stiffer its set, the more bouncy the rear is... and its not a small amount, the rate of decrease in ride quality is alarmingly large at each click stiffer. It also makes noise at any setting, squeaks and such that progress to clunks and other alarming noises.

I've talked to a lot of people and they dont know what it is... i've checked and double checked all bolts. I wanna get some feedback before I take apart my rear suspension again and waste more time. Please Help!

 

OK, i cant sleep, so i was able to think it through... DMS recommends STi Rear Top Strut Mounts for the DMS 40's... and many say the ride is compliant and quiet with this set-up. Then there are those who used the stock ones (like me) and they have clunks and rattles, etc. So... the problem is most likely the stock rear top strut mount! (since everything is tightened down and it is installed correctly)

So, am I right or completely wrong?
