I have not pulled my tranny yet to look at the disc to see if this is what happen. I know I went to power brake it to heat the tires and it slipped at 5K rpm's and I smelt the disc turning and burning and not the tires ( OOppss ), then I lost all engagement. So it all comes down again and I got a Nismo G-force Twin disc set up going in that's rated some 750Tq and 800Hp. So I shouldn't judge what I haven't seen yet, but like the last time, I'll post pictures once it comes out. :)
