Re: What do you think about this bolt on is it worth it
729 for a driveshaft? RU kidding? Look at a local driveline shop and they can probably whip you up a custom one for about a 1/3-1/2 of that. On a stock car this is largely a waste of money.
Are you planning on putting 900 hp into this car? If not, I'd spend that kind of money on performance you can feel like putting it towards lighter wheels, a set of good shocks or a good tune, whatever floats yer boat.
