As mentioned in my own build thread, I also ordered some CRW heavy duty inner CV joints very recently. I wasn't sure if I would ever bother, but a broken CV joint can cause serious damage to other things (eg. transmission case) as it flops around. Also, I now have a torn CV boot anyway so this is a good chance to combine the labour cost. I'll post an update when I receive the CRW kit in the next few days.
Something else that may be of interest...I just found this thread on MR2OC which compares the ATS and CRW upgraded CV joints:
http://www.mr2oc.com/showthread.php?t=464887In that thread, ATS and CRW both replied directly with their own comments.
ATS said this (quote):
"The ATS [joints] are custom made from chrome moly steel and are dramatically stronger. I'm not going to bad mouth CRW. CRW are cheaper and they are a good joint. ATS are more expensive and they are the strongest you can buy."
CRW said this (quote):
"ATS went the route of having a chromoly inner race made to accomodate the larger chromoly race needed to hold the power. they did a great job doing so. we found a different approach to making stronger CV joints somewhat by accident. in the end were able to get a more complete package to the end user for a competitive price. i have customers ask all the time which is better... CRW or ATS and the answer is both are great. both sets of CV joint upgrades have their pros and cons but at the end of the day the customer can't go wrong either way they choose."
NOTE: Both the CRW and ATS CV joints have thicker cages, which is the most important thing, and the reason why both solutions are stronger than stock.
