1. What direction are the centerlock hubs on the Right and Left sides of the centerlock porsches? (is the left side RH, and the right side LH, or both the same, etc?).

2. What torques are recomended? I now many just use impact guns, if so, whats pressure/torque are you setting it to? I know some centerlocks use 1200ftlbs like trans am, and formula/sports cars range from 125-300.

Thanks

FWIW -

My GTP car was 600 ft-lbs
My Can-Am car was 450 ft-lbs

I used a big torque wrench to calibrate my impact gun so I knew what pressure to run. Periodically I would use the torque wrench to check and make sure it was tight.

Interesting, thanks.

And they were all Right hand thread I assume?

The left side tightened clockwise (if memory serves) and the right side tightened counter clockwise.

Yea thats what I thought.

Ok thanks

On a Porsche the center locks are right hand thread on both sides and torque to 350 ftlbs or so.

I assume you mean the 996 Gt3 series?

I guess they did that so its easy for the pitcrews?

B/c techncially the diagonal corners should have similar threads, b/c the front wheels will have opposing forces from braking and rear wheels have opposing forces from impact/acceleration.

Thanks!

As far as I know, all of the 911 based factory race cars (964 and up) use right hand thread centerlocks on all 4 corners. As stated previously, the correct torque is 350 ft/lbs.

The centerlock nut requires a 32mm socket to remove it (or put it back on!).

I use a 3/4" air gun driven by a nitrogen bottle.
