so my 00 zr rear suspension just doesnt seem right-its way too soft in the back-id say with me on it it sqauts 6 inches or more. ive got the springs cranked all the way and brand new rebuilt ACT shocks. sled only has 500 miles on it. im fed up. now i have this weird vibration coming from underneath at slow speeds too. how an i make the the rear suspension as stiff as possible? i got on my friends xc with M-10 and its like a different world, but theres no way im gonna spend 1200 big ones on a set up like that-any ideas anybody?
