Kyle82484 said:I have an '03 Mustang GT and I am considering getting some 4.10 gears, I have been reading some other threads regarding gears, but I am wondering what specifically will a set of gears do for the performance of my car, such as a set of 4.10 gears? I saw someone posted that it affects the overall top speed of the car? If so how much? Are 4.10 gears the best ratio for my car?
FunkyBoss said:Good observation Stonecold! Does a Supra have a 6-speed? If so, that could very well be the advantage.
One question you should ask yourself Kyle, what are your plans with your setup? Are you setting up for the 1/8th? 1/4? road racing? street racing? running from the cops...J/K of course. My setup if mainly for the 1/8th, with and occasional 1/4 when I feel like making the long trip to MD, and of course the occasional street race. One thing I will not be doing is racing 150 MPH down the highway, my one race up to 110 was more than fast enough and I punished myself for doing even that. What ever you decide to do, have fun and keep it safe!
FunkyBoss said:I just don't trust those calculators! According to the one on this site, I should be running at about 3000 RPMs at 80 MPH, but I'm not. Now I have read that 03+ GT's have a .62:1 5th gear ratio as opposed to a .68:1. If this is true, the calculator estimates 2650 RPMs at 80, which is exactly what I run :shrug .
carguy1985 said:What year is your car.... because those gearing are pre set for a T 45, the 1st gear and 5th gear ratio are just a tad bit different with the TR3650 in the 02+ cars
1st = 3.37
5th = .67 (little bit better O/D)
