I installed the 70 durometer AWR MM around 5-6 months ago. In the beginning I was very happy with it, no wheel hop...!!, but a lot of vibrations from the inside. Now it feels if I am driving with a OEM MM, a lot of wheel hop, just like with the oem one, but with the same annoying vibrations. Anyone experienced the same thing? I think I might go back to the stock one. Any ideas? Thanks in advance!
