Composite LWB drift build

Started with a composite LWB chassis
17mm hubs technically fit on the kraton 2wd stub axles if you put a whole bunch of shims behind em, they never broke at least, so I ran cheap 17mm tires.
Drivetrain: Ran a castle 15xx with a 17 tooth pinion and normal metal diff and no center axle (ofc)
Suspension: Infraction front shocks, rear shocks have a mojave 6s body and infraction piston to make em a little shorter.
Electronics: futaba gyc gyro, futaba radio

Review:
It absolutely slid with 0 effort, and I ran through plenty of tires with it.
But: the weight balance was shifted way back with the motor and diff in the rear and ended up being pretty hard to drive with a heavy 6s battery. A smaller 6s worked better but one lasted for like 8 minutes tops.
The spin outs ate tires pretty quickly and composite slider axles couldnt handle the force either.
