I have a 2009 Challenger SRT8 with the 6 speed manual transmission. It has terrible wheel hop when launching the car at the track. Are polyurethane rear subframe bushing kits the best place to start or is there somewhere better to start? If the subframe bushings are the best place to start, I have used prothane before on other vehicles with no complaints but the kit is $235 with a 10-12 week delay. BMR sells a bushing kit for $199 and looks like it is currently in stock. Anyone have experience with BMR? https://www.bmrsuspension.com/?page=...988&superpro=0

 

Is that independent rear suspension?

 

Yes, all LX/LC platform cars have IRS.

 

Normally, I would suggest ladder bars, but, on an IRS car? Don't know if that would work, or if they even make them for your application.

 

You can also consider a brace.
