Nice site, friendly people, been getting good info. First off, I've done some searching and most everyone is saying the 03 GT came with 3.27 rear gears with the 5sp. I put my specs in the calculator, [email protected]=3.08 ratio. Does this sound correct? I haven't found any definite answers regarding what options were available. Second, I'm looking at a new shifter and drove a friend of mine's 98 with a B&M ripper which had a great feel, I've read good things about pro 5.0 and steeda tri-ax, I'm open to suggestions and feedback. Third, looking at x pipe and cat back from bassani or slp, my friend from above has just bassani mufflers and it sounded way better than my ride, will the slp give the same or better results? Also, with the x pipe will it cause any errors with the computer? I'ld prefer not to have c.e.l. on after my mods. I'm looking at stut tower brace and upgrading my subframe connectors with weld in style, how much more firm will this be over the stock setup? Has anyone noticed any performance differences between traction control and no traction control? Last thing, after the car sits overnight, I've measured the ride hight in the rear and the left sits 1 3/4" lower than the right side. I drove it to a local dealership and by the time I drive it over the hight difference is closer to 1/2" off. Granted, I'm not the smallest guy but on the other hand I'm not really overweight. Anyone else have any similar issues? Thanks for the input.
