hi nameunchanged think they are tamyia and possible team associated pancars with foam wheels and live axle with gear and differential attached , were
good for running on smooth carpet indoor racing , in front of the steering they used a piece of foam for protection underneath the 1/10 scale lexan body
gears were 48 pitch gears batteries used were nicads , the body mounting posts on 2nd vehicle look like a team associated type pan car ,they also make these in 1/12 scale pan cars and are really fast and hard to control , some are now made out of carbon fiber , alum., fiberglass ok hope i helped mugey
