Custom Jag IRS strength? (Pics inside)

[750hp]

Thats interesting. If it didn't happen when launching from a standing start, was it when releasing the clutch on a gear change or just rolling on the throttle in gear?

Remember there are two flavors of spider gears, weak and strong (2 versus 4). That item would be good to know....

For the half shaft it's diameter what counts. But your shocks get in the way soon. My buddy twisted the XJ half shafts often until he used some that are dimensioned similar to Corvette shafts.

His car is much less powerful than yours (10.6s E.T.)

My car had more torque, but I ran street tires - occasionally Hoosier Street TDs on public roads, never on real drag strips. Mine was also very light which helped (920kg).

Look what CAN-Am cars use. Amazingly thin control arms and reasonable diameter half shafts. I am not near one to measure.

Good luck!

I have the 4 spider version. I am not sure if the spiders took out the side gear, or the side gear took out the spiders. I had 4.56 gears in the car at the time, so it wasn't really hard to break the tires loose going straight or around a corner. There was no 1st or 2nd gear. I did not even know they were broken until I drained the oil and a chunk fell out!

There are guys on another forum I visit that are using C5 (I think it was C5) Corvette IRS set-ups that are all aluminum. They are running 1000hp on a turbo LS engine and they seem to hold up.
