Mike installed my Quaife LSD today along with a new pivot ball and TOB as well as a clutch swap. He also found that one of my booger bushings was broken and causing me plenty of shifting problems as well. He is a knowledgeable, reliable, ethical, and a very cool SRT specialist/guru as well as a pleasure to deal with.
My car is now very, very stable in the highway and first gear with 2 tires gripping makes driving the car a hell of a lot more fun. If you have an 03', your next mod should be to get an LSD installed as it will increase performance in braking and in handling.
Also the car now runs like new and I never thought for once that the car would run a million times better after a clutch and differential swap. It now goes up hills without a problem, the engine is now working with ease under loads, my gas mileage is better, the exhaust is very quiet, no slipping in first gear or under WOT, and the car feels a hell of a lot faster.
Thank you Mike for all the help--you have my business.
