1st run was 12.4, 2nd run was 12.6 and 3rd run = Boom

I opened up the diff and there were 2 one inch chunks of metal. Looks like it broke inside of the diff. the R/P was fine. The axles splines stripped out where the axles go into the diff.
I ordered KAAZ 1.5 and now putting it back together. I'm not worried about the Diff but now i worry about the splines on the OEM axles.

Anyone have this same problem? I know that they make stronger axles but do they make stronger axle splines?

My upgrades are: Intake, FMIC, Full exhaust, PFC, Stock turbos at 12psi.

Thanks

 

I bet you didnt take the slack out of the driveline before launching the car.??

Kaaz with race axles and you will be fine. Call Ari rx7.com and he can get you what you need.

 

Driveshaft shop.....Level 5 axle/hub assemblies

 

No I didnt pre load the driveline.... I learned the hard way.
2 G's for the axles... wow... i gotta save up for those.

Thanks for the info.....

 

The level 5 bar upgrade with the Kaaz and stock axle stubs will be sufficient for a long time and is much cheaper.
