Sorry Jim, but the gear train in my MO5 V2 is very free, even when hot. My car uses the standard spur and and middle gear as supplied in the kit, ( white parts), and Top oil gear diff. I am also using the steel gear shafts as the weight is good in the front end. I also use Nulon Ezi glide clear silicone lubricant on my gears. Never had an issue with it.
My droop screws are not used as I am using my shocks directly from my MO5 V1built to 56.5mm in length. I use three hole pistons and 350 weight oil front and rear. The car is setup to suit my driving style and work with our control tyres.
Anyway have fun racing
Calvin.
