Supension help

[waldo31031]

I was wondering if I would need anything other than a torque arm,panhard rod, and trailing arm and relocation brackets for my A4 SS. I am about to have between 450-500 hp. I want it to hook up at the track. Any other suggestions will be appreciated. Thanks

Also, will the rear end hold up?
