Ok so, when I try to launch with traction control off, I usually rev up to 4000-5000 rpm and dump the clutch and the wheels start spinning but I hear 4 to 5 very loud clunks or bumps coming from under the car. Is this wheel hop? Or something else? What is causing this noise and what aftermarket parts can I purchase to eliminate this issue?
I want to do some legally sanctioned 1/4 mile runs down at the track and would like to diagnose and eliminate this issue if possible before going there in the spring.
