Please help a JRXS-R sedan noob here...
I"m going to be running 13.5 rubber/asphalt & foam/carpet & I"m trying to find out gearing for both so I can order gears.
I was told with a 108t 64p spur, I would need to be in the low to upper 50's on pinion,but when I try to calculate it. I come up with high 30's to mid 40's. Am I doing something wrong? What would you seasoned drivers suggest I be starting at?
Thanks for your time, Ron
