COG for 72 FJ40 (1 Viewer)

[DWDTOY]

Trying to decide best COG set up for rock crawling in 72 FJ40 . Current set up. Spring over, shackle reversal, rear tires moved back couple of inches, stock F engine, SM465, Orion twin stick, front and rear ARB lockers, heavy duty anti-wrap traction bar, longfield super axles, disk brake conversion, 40s on 17" trail gear wheels, warn winch up front. Trying to decide whether to mount my spare tire on a mount like this JCR universalmount
Prerunner Tire Mount Universal Powder Coat JCR Offroad
or buy a rear back bumper with a center tire mount? Please advise...

Best center of gravity? wth are you talking about

Getting the tire lower and farther forward is better, but you would have zero interior room with a 40" tire in a 40. IDK if it'd even fit.
