I was just about to post this same topic. Jacked up the car yesterday to do my clutch swap. Both my stock steel and aluminum shafts have failed evidently.

We run a steel one made by Saddler in the gto 725hp, forged yoke. I run the stock one in my rx-7 550ish hp.

Saddler had one for a turbo 400 in stock. If not Jegs has them http://www.jegs.com/i/Strange-Engineering/873/U1661/10002/-1?parentProductId=744500.

i say if you're going to do it, go all out and get 1350 U-joints. for a little bit more now, the added peace of mind is worth it IMO.

is there any downfall to 1350 u-joints besides price? I can't imagine the extra weight really amounting to anything.

not that i've ever heard of anyway. and with a car as light as yours, the driveshaft would probably be good to go for years and years.

You'll never notice the few grams more a 1350 weighs over a standard joint. When your dealing with something so small in diameter it take a lot of weight to notice a diffefence. Just like a multile plate clutch weighs as much as a standard diameter clutch, but revs faster because the weight is near the center.

I've been running a steel one from sadler with 1350 Ujoints. like slvr said its so small in diameter the rotational inertia is hardly effected by the different materials, theres alot better places to spend that extra money and the piece of mind of running steel is worth it IMO
