Bolt in Sprag For 904 Trans

i don't know that much about them. but i do know the thread your talking about and that a 904 will handle 450 horse no problem when put together properly.. :)

i'll have to assume that the guy knows what he is going in there and using quality parts. bolt in sprag is definatley a nice saftey device. definatley do your burn outs in 2nd gear.
