for the few times i ran an SB i liked it, mine was also built like a tank, i loved it just didnt have the time to run it
so i now have two forsale, i think the info is still somewhere in the forsale part of this site. my brother used to own an MR4-BC special which he thought was a great car, he just couldnt get it to run correctly, i think it was something to do with one of the diffs
im not sure, hope this helps.
