BRCA Handbook

23. Construction Rules - General

23.4 "To be eligible to compete in the 4wd class, 2wd cars must race at 1588 grams minimum weight"

I presume this means if you want to enter your 2wd car into a 4wd race you'll need it to match the 4wd minimum weight limit of 1588 grams. (If you run a 4wd car in a 2wd race it'll already be over the 1474 grams minimum limit)

For reference, mine, complete with wheels, PT, battery etc weigh as follows:

TM2 v1 = 1593g
TC02C Evo = 1504g
BSR BZ 222 = 1640g
