wanted - mad rat roller
 

want a cheap as chips mad rat as a backup to my b4. not interested in blingy hopped up rollers.. standard car for cheap monies. whyg?

Get a 2nd B4 instead - the Mad Rat won't serve well as a backup principally because wheel fitment will be a royal PTA, eliminating any cost benefit to a cheap roller (which will not go for much less than a new one).

Its easier to fit 12mm hex wheels to a B4 (using XXX-S or TC3 hex kit) than it is to fit B4 wheels to a Mad Rat without wheel hexes (axle width is different). Front wheels are completely incompatible.
