My friend drilled the rear rotors to fit the 5/8 studs. Fronts came drilled and slotted. Before the race tracks open up next year, I'll replace the brakes with Wilwoods.
As for driving on the street with my helmet on, I still might. It's just too damn cold to be driving without a windshield right now.
When I took the windshield out, I cut the rubber since I was replacing it anyways. Installing it was a *****. I'll never do it again. lol
