I'm not really a brake guy, but any improvement over the stock OEM brakes would be just that-- "an improvement". I would defer any brake questions to our "Big Tire Club" guys like L-Dub, LittleBeast, JoFotoz, and Tom4Bren. Those folks can attest to the effects of using huge heavy tires more than anyone on this site.

My advice would not even venture into troubled waters if you don't have to and try to limit your maximum wheel/tire combination weight to a target of 72 lbs (which is a safe 10 lbs over the '00/'01 VX stock wheel/tire combo). Here are just two(2) examples of the 72 lbs target combo's using both OEM version wheels (16's & 18's):

1999 OEM 16x7 rim (20 lbs) + Yoko - Geolandar M/T+ in 285/75R16 (32.9" O.D./51.6 lbs) = 71.6 lbs

'00/'01 OEM 18x7 rim (28 lbs) + Grabber AT2 in 275/65R18-116S (32.1" O.D./42.6 lbs) = 70.6 lbs
