few questions on upgrades

[discgolferlee]

so sold my honcho a few months ago but now have another scx10. it has a pro-line jeep wrangler unlimited body. it has steel driveshafts already. was thinking of a few upgrades and wondered what thoughts everyone has on these.

for sure getting the robinson racing 1 piece diff locker as well as the hardened steel idler gear.

some other upgrades I have been thinking about but don't have funds to do all of them right now

rc4wd rock sliders

possibly an aluminum front bumper. rc4wd rampage possibly

aluminum front knuckles and carriers

but one thing I am really interested in is the hardened gears for the axles.
I want to increase steering/turning radius and read that over dirving the front or under driving the rear will help with this as well as climbing.

any thoughts on this.
was thinking of underdriving the rear since i have quite a bit of wheel speed. and getting a hardened stock set for the front.

please any thoughts input on these upgrades.
