Wavetrac Diff
 

Since one axle is to be changed in order to fit the Wavetrac diff I was wondering if upgrading the axles to the 1200hp Pro-Level axles worth the money? Do guys with 750hp turbo setups run the OEM axles?

The stub axle is changed that goes into the diff. Not the axle. Yes, I do have upgraded axles. It depends on what you are going to do with the car if you need the DSS axles. At 800whp or higher is when they are needed or if it is going to be a 1/4 mile car.

Does the OEM timing belt fit the lightweight Stillen standard crank pulley or I should buy a gates aftermarket?
