Exactly what does it take to make an 03 Cobra stop wheel hoping?

The other thing that realy bugs me is ya know when you have a lot of power, and when you get on it the back of the car does not have a real solid directional feel to it? anyone know what the best fix is?

Is there one thing I can do to stop wheel hop, and always have a strong solid feel? thanks

Well, unfortunately there is nothing that will completely remove wheel hop, but I completely understand what you mean about the rear-end.

This is a list of things I'm going to do or have already done (assuming you mean for street driving)

Urethane bushings throughout the rear-end http://www.maximummotorsports.com/irs-asp.asp

Lowering Springs (H&R seem to be what most people are running) http://www.maximummotorsports.com/HRsprings.asp

To stiffen up the side to side motion I'm going with a Kenny Brown rear shock tower brace http://www.rpmoutlet.com/03kbpart.htm#1

Also a good set of sticky tires will help you out a bunch (Nittos, MT ET Street Radial, BFG's) not good in the rain though!

For durability and depending on what power level you are at these two items will also help the rear-end last;



Hope this info helps you out, although these items are pricey, it'll pay-off in the long run when you don't have to replace the rear-end if you break it!:)

I had the same problem, but now I have almost completly removed wheel hopp. I installed the hard launch kit from www.rpmoutlet.com (http://www.rpmoutlet.com/) along with the urathane bushings. Also I have the Kenny Brown rear strut brace. I have also installed Steeda's www.steeda.com (http://www.steeda.com/) differintal brace, to protect the Aluminum cover from breaking during hard launches at the track. There are allot of braces out there, but I picked Steeda's because it had two Gussets and is made out of steel.

A good set of BF Goodrich Drag radials helps me allot too. Every since I have done this no more wheel hopp, I have also lowered my car with Steeda Sport springs, and I left the bushing out on the top and bottom. In the front I also lowered with Steeda springs along with the x2 ball joint and the Bump steer kit. Also the Kenny Brown Cross brace. It's now set up perfect to me for racing. ZCan't wait to return to the track!

I just have to work on the right RPM's to let it go because I can spin the wheel pretty quick. I am up to 500 HP at the wheels, with 542Lb torque at the wheels.
Good luck!
