How far can I push it before it will break?
My best 60ft at the track on street tires is 1.99.
I have a m6, all the bolt ons, cammed(226/226 575.575 112+4), and spray. I haven't sprayed at the track yet...only on the street when I needed it for a few races.
I have about 120 runs on my 02 Z and am on the third rear end. I have it at a shop right now getting a hybrid 8.8" Ford w/4.10's installed. I figure the stock 10 bolt is worth about 30-40 runs before it self destructs. I launch at anywhere from 2000 to 3200 depending on track conditions with Nitto Drag Radials. Two weeks ago at Kennedale it ate it big time. CLUNK, CLUNK, CLUNK as I turned left coming off the track. That made my mind up to go for the 8.8". Cheaper than a Moser and a bigger selection of ratios if you decide to change gears. 10 Bolts inhale bigtime!!!
