Gradually evolving performance is something that can make or break one's budget. Replacing items several times can be expensive and frustrating-first adding a gearset, then breaking an axle, followed by the differential-whereas if we had done it right the first time, it would have been cheaper in the long run. It's important to plan ahead and make sure your expectations are realistic.

A rearend is difficult because it impacts the brakes, wheels, and tire size, in addition to axles and differentials. A properly set-up rear will retain the same tire clearance both during launch and sitting still. We have already made the decision that our car will be mostly dedicated for the strip, and choosing to build a bulletproof rearend with a killer suspension was our goal.

Most builders will agree that the most intelligent approach to our project is to choose the rear tire we're planning to run. When you know what rubber will hit the road, then you build up the rear and suspension from there. Our project car is an '01 GT with a 600hp ProCharged Two-Valve mod-motor with a Ram twin-disc clutch and a Tremec TKO-600 transmission. We would like to run a 275-60 drag radial or 28x10.5-inch e.t. street tire, so that cast the die for a complete revamp of our rearend, which brings us to the story at hand.
