Drivetrain Differential

I would leave the rear brakes and just upgrade the front to the Cobra rotor and calipers. Stock axle is 28 spline and is adequate. The 95 GT differential is a limited slip. Check the gear ratio as most have been changed by previous owners. The quick and accurate way is to count drive shaft rotations for 1 rotation of the rear wheel. For example, if the D/S rotates 3 1/2 turns with one wheel rotation the gear is 3:55. If you are serious about keeping the car put an OBDI reader in your tool box. Cost is about $22 and will save you $'s not spent on parts by guessing and replacing good parts.
