I had Rich at Backstreet Performance in Medina, OH slap a Pedders Justice Package with the Supercar Coilovers on my 2011 SS. It included a complete bushing replacement and the addition of stainless steel brake lines. I couldn't be happier with the finished results. The new suspension gave me the clearance to fit 20x10.5 Forgelines with 305 tires all around, with no issues.
The car is now deceptive in how nimble it is. I did have time to take it to the track, but while on the street, I never found the limits to what this suspension is capable of, which tells me it must be pretty high. Body roll was eliminated, and the car now always feels planted, even over bumps during turns. The ride is firm during hard driving, but smooth enough on the highway and while just cruising, that even my Mom loves to drive it. The larger reservoirs really make a difference.
During hard launches, the car just squats, hooks and goes. There's no hopping, or sideways sliding, so Rich did a great job with the alignment. I pulled out from a restaurant after breakfast once with a buddy behind me once, and got on it. His exact words were, "dude, that thing just hunkered down and was gone."

Thanks again to Rich at Backstreet and Pete at Pedders. They really do make an amazing product, and I'd recommend having your car Pedderized to anyone out there that love to drive their 5th Gen.
