Well... my set is on and all I can say is WOW!!!! Before, anything over 40-50% throttle, the tires would break loose (on street tires). Now, I can go to about 70% throttle and the tires are barely spinning with the drivers side squealing more than the pass side. Good thing I have airbags and HAL shocks to tune with. Can't wait for the track!
As for installation, my set were done with the car up on jackstands. I went to Race Prep and had Bryan do all the work. He did have a few things to say about the installation. 1. You don't need to bring out the torch to bend the plates to shape. He used a hydro press and a vise with a 5 lbs mallet to get the contour right along with test fitting. After about 3 trips back to the car and press, he got the curve just right. 2. Use the LCA to align the holes. I unbolted the LCA from the rear end and put the bolt through the plates and snug them down. Then we used a jack to bring up the arm until the plates mated perfectly with the rear end. He proceeded to tack weld the plates and then removed the LCA to complete the welding. 3. He didn't weld the area where the LCA would move up and down. He thought welding them and then grinding the welds would be a waste of time and not yield anymore strength. He said that welding the outside was sufficient but welded them on the inside as well except for a 2-3" in section for the LCA.
I haven't installed my swaybar yet (HO Racing) so i can't say if it fits upside down. The SS is "fun" to drive without any sway bars now!
