So, I have an 01 Cobra that likes to hop around when I jump on the throttle really hard and/or spin the tires. Basically, whether I am simply accelerating a little hard and getting minimal spin or dumping the clutch to put on a show, the rear tires will hop and jump like crazy. They will not hop and jump however if I am doing a donut. This condition is the same whether or not the traction control is engaged.



The Ford shop just completely rebuilt the internals of the rear-end. Any idea what is causing this, or is this a design flaw?



Thanks for your thoughts,

Firm up your rear shock valving and springs, see how that helps you.

I dont remeber if that year cobra is IRS but if its not get yourself some traction bars.

Yes, it is IRS.

I don't know if this will help since my cobra is an 03. My friend replaced the rear bushings with some polyurathane ones and said that fixed the problem. The fix was cheap but the labor was hell including removing all the exhaust.

you could always go with an solid axle set up that would definetly cure the problem.(wouldn't be cheap)

Indepent axles are great for handling but they stink if

you want to drag race(wheel hop)

I have a 99 cobra w/ same issues. Replace pinion support bushings with Steeda poly urethane(the exhaust does NOT need to be removed ) apporox 15 min job. Also a higher spring rate makes a dramatic difference( means lower the car)

My 97' Cobra has "0" wheel hop. My 95 Stang did. No mods and who knows why???
