Hello, i bought a 01 m5 4 months back or so and I do love the car, I acutally sold my large screen 16:9 becuase of a scratch and drove with no radio for 3 weeks, in this 3 weeks I have noticed a squeak coming from my suspension which i though would be thrust arm bushings and rear ball joints.. so i replaced them thinking even if its not i would be time soon.. ( turns out they were bad..)also had the famous sway bar mount replaced in the back as it was broken also, the car does feel alot tighter, but the sqeak although not as bad as before is still there, I have the Dinan s1 package with dinan stg2 suspension with the koni yellows, im starting to think its my shocks under quick compression like pot holes man hole overs etc.. does anyone have experience with this happening? on a side not.. also had the EVO 3 installed with DSSR and that is one nice upgrade 
suspension looks to be installed jan of 2001
