Had the Roush Suspension kit 401296 installed today on my 2007 Mustang GT. The shop that installed them reused factory Jonce Bumpers instead of the new ones that came with the kit. Should i have the Roush ones installed car only has 6000 miles.
Thanks Again

 

If the car is lowered like I suspect the Roush kit does, you need the jounce bumpers changed. The stock ones will give you a very harsh and unpleasant ride. They are easy to exchange, just jack the car up, pull the wheel, and it's only a couple of screws in the mounting plate holding the bumpers in place.
