[QUOTE="HrsePwr, post: 15435408, member: 171486"] Hi, So I brought my 2011 5.0L conv. To the track stock. And it had VERY BAD wheel hop. I had to take off at idle. It ran 13.4@108mph. All traction controls off. I could not even take off at anything above idle or there would be VERY BAD wheel hop. So I bought some brand new : Steeda Adj. UCA, Whiteline lower control arms. And a local was giving away a " free panhard bar which is adj. He thinks it was an SR brand one ? " , as he sold his GT. Anyways I noticed that there seems to be a lot of flex on this Panhard bar. Like if u try and shake it while car is on hoist , it flexs quite a bit. Anyways wheel hop is 100% gone. Doesnt even matter what Rpm's. But the car is VERY UNSTABLE. Smashing 1st-2nd gear the rear end is EXTREMLY UNSTABLE , going to 2nd to 3rd same thing. And going 3rd to 4th @ Full throttle same thing... So at track I had to run with full traction on and it went : 12.7@116 with a 2.0' foot. Im assuming : Rear panhard bar is defective as it flexs quite a bit ? Perhaps Steeda UCA is not at correct angle ? Alignment slightly off ? Today I installed a Aluminum 1 Piece drive shaft and after driving it around to ensure everything is good I decided to floor it..... and WOW THE REAR END IS EVEN MORE UNSTABLE. I ordered Bmr Drag springs , Koni Shocks , Lower control arm re-location brackets, a new panhard bar and a panhard bar support brace. After that i will get the car re-aligned. Any ideas ? [/QUOTE]
