Scott, I never heard of somebody doing that. Just the raised part of the hat, or all the way to where the friction surface starts? What color are yours?
I did the hat up to close to where the friction surface starts. Here's a pic. I was initially concerned about heat, but the shop that did it has done numerous race car rotors, so I thought I'd do it. After 10,000 miles, they still look great.
Got the suspension mostly done. Still have to install swaybars and align it.
Still trying to figure out ride height. The initial height with the SPC springs had it slammed (in my opinion).
We raised it an 1.5" on the lift and I think that's where I like it. The SPC LCAs come with shims so the front shouldn't be a problem, but for the rear I'll have to get spacers.
