Going to lower it about another 0.5" around, then align and camber it.
Came close to getting the lip polished but was quoted $240 for it and would rather buy some volks if spending all that money.
This way I can do a vinyl lip in red with custom text or anything I want and its temporary.

Huh? So how does heating my wheel to 350F for a while affect the strength of it? The more time you heat the aluminum over its transition temperature, the more you undo the heat treatment and weaken the wheel. There are tables that summarize this (none handy, but Mil. volume 5 comes to mind), but you have to know what Al you are heating. To be safe, I'd suggest coating with an epoxy resin that softens (goes from powder to the smooth coating) at ~275F; definitely below 350F.
