@pickle Go to driftmission and play with the cs calculator in tool area.
FDR final drive ratio is your spur pinion combo. I stay around 6.5 to 7.5 fdr.
I like 64p because they are a little quieter thats all and I have an assortment of gears to combine.
So I put a 16T oneway pulley and swapped the original 38 with a 36T. Then I changed the rear 22T to a 20 and have 1.50cs now.
The car feels really good now. Going to put on some Raikou's now. Should be interesting
