Oh, be afraid. Be very afraid. I'm only thinking about it. The proper solution is to send the rear wheels back to Kinesis Motorsport and have them swap rim halves. They will need to swap both halve since I want to subtract 1/2" outside and add it back to the inside. That's the right way to do it and that's why I spent the big bucks on modular wheels in the first place.
But Twist Machine is my top (one and only?) priority lately, so I'm considering doing the nasty. I have 1/2" ARP wheel studs so the taper has plenty of surface area/clamping force--and we are dealing with forged aluminum here. But the wheels may still crack. What is it? Measure once, cut twice?
So I will stop here. Roll my wheel well lips and call Kinesis.
