Good luck with that plan. I hope it works well for you, but I am told by a very knowledgeable Quaife diff racing mechanic that studs will not cure the issue with the Autotech Quaife.
Not a "Quaife ripoff" at all. The Quaife m/c diff was license-built in the USA to Quaife's specs for about 8 years, and when the diff came out it was the best thing going for a m/c powered racing car, bar none. The problem was that the market was too small for a manufacturer to invest heavily in, and eventually they threw in the towel. Furthermore, you guys complaining about them are all racing parts that have seen hard duty for 10-17 years. Are you still running that '03 Yamaha R1 you installed 15 years ago? I thought not, so cut the old Quaife some slack!
And don't forget, Taylor and Williams each had their own issues when they first came out. Our community is lucky in that they both are headed by highly experienced and dedicated engineers whose love for the sport overcame their business sense.
They invested in multiple upgrade programs to solve their products' shortcomings, and now we have TWO world-class diffs to choose from.
But back to the Quaife. We do carry the ARP bolt kit and some other common wear parts, but there is no substitute for installing fresh bolts once a year, and torquing them correctly with
RED Loctite. And check those bolts' torque every few events!
