If you have not already upgraded to the Gen 3 rotor set and housing, you should hold off. I just heard from Whipple that the Gen 4 rotors are in the works for the Raptor's 2.9 liter housing. They will be made standard in the Raptor kits going forward. Should be ready within the next few months.
Side note: anybody interested in a low mileage Gen 3 unit?
