Steve, finally got a look tonight. The way my mechanic did the rear, the alignment wasn't even touched. He really didn't have any problems at all with the install....this coupe is insane with A/S radials on it....they aren't going to last long....I didn't do the resonator delete this evening, I am going to do a new muffler instead...need to do some looking...Roadster was a piece of cake after the coupe...I feel like I now own two new cars...they finally behave the way they should....loving it...back to modding again....thank you guys for the wavetrac....nice piece of work...
