Blew up another CV joint..., What to do? Options

[yarin]

So I need some advice on this one:

2 years ago a CV went on me during an autocross, drivers inside (tranny side). The bearing race cracked and well, u know what happens then, no power transmitted means flatbed tow truck home. Replaced all 4 CVs with the kit from PMB performance.

All was well.... fast forward to today, the exact same joint blew. I haven't dissasembled for a post mortem but it isn't pretty. Luckily i flat tow the car to events now so getting home wasn't a problem. The car definitely took a beating today, put about 45 total runs (autox school x 2 drivers) on the car before it let go on Avon Tech RA tires, a few areas of the course induced some slip/grip stress.

Motor is relatively stock, probably putting out about 100-110hp crank. AutoX definitely put exess wear and tear on the part, running semi-sticky tires.

So what should I do, replace with another kit? OEM? Beef it up with 944 or heavy duty CVs? Any of you fellow autoxers have a solution that won't cost me a fortune?

Thanks!

Make sure the tranny is centered between the trailing arms.
Also, with the rear off the ground and the trailing arms at full droop grab the axles and make sure you have plunge in both directions. Next remove the springs and run the trailing arms to full bump, (stopping on the way up at ride ht) then recheck the axles for plunge.
The fact that the two failures occurred to the same joint position has me wondering if the tranny is off center.
If the drive train is moving in the car in hard corners it can shift toward the outside wheel and jam the axle. Look in the inside of the tranny drive flange for evidence that the axle has been jammed into it. Use only Lobro joints. If everything is installed correctly it will take more torque to break a CV than you'll get out of a normally aspirated 2.0l. A lot more.
