I installed without any shims at all. After 10 miles or so its opened up to a tad over 45mm. Its still not a consistent clearance all the way around but its a lot closer. I went in the car to buy a new camera and while showing the tech how my camera is now in the shape of a V it started working. How about that. So give me a half hour and I'll post up the few pics I have. She's running good and strong. Oh, I never put my hand on the stock belt after driving so I have no idea how hot it got. After being in boost and parking the car I took a look to see if I could find sighs of slipping. I couldn't. But the belt is almost too hot to hold. I know if its slipping it will get much hotter than normal so if anyone knows what is normal, please share.
