sounds like we all agree to never fully tighten and back out cause it's the best way to kill the diff before even running it
I will still try to hold the spring compressed for a few seconds at the next rebuild and see if it makes a difference
So we habe T/C balls, they were steel before (as I assume they were not ceramic)? HArder balls indeed can diminish the tuning window as they compress less.
I still use AE fluids, stealth lube and black graphite grease... Haven't even tried the x-gear fluids. All kyosho bias aside, would you recommend them fully?
Cheers gentlemen
