600hp

Hello! So I'm to the point that I need to order custom axles for my RCR GT40 project. I have a source recommended by Fran that's back east but was wondering if anyone knew of a source on the west coast, Los Angeles or adjacent that I can get a secondary quote. I need the axles to handle 500...

Just bought my 1st 40. Looking for tires. I have 15" rims, and I am looking to go wide rear to handle the 600hp. Will the 295 Avon tires grab? Mounted on a 12" wide rim? Any help is appreciated.
