[gt500]

Like the title say's. I have broken two coast aluminum shafts rated at 700hp. My car puts out around 600-650 ran a best of 7.35 in the 1/8 on drag radials. They have both broken at a 3000rpm launch. A buddy tell's me to go with carbon fiber. I have looked online seems like a good idea. Just alot of coin and would like to hear from someone who has used one. Thanks

I bought one for my Camaro, 5.90's on an IRS 3900 pound car and it worked great. You won't regret it.
