F1-Fanatic, I AM going to race on carpet (Ozite I think) road course, It's just that the person I bought it from had no idea about set-up
The ride-height was about 3mm it's just that the body posts were the wrong length and made it look higher, it's sorted now
I tried it out on carpet at a bowls center (not bowling, it's a weird game that elderly English people like ) after a practice buggy race and it went pretty well. The carpet didn't have very good grip but it was OK
There's no minimum ride height at the track so I may go a little lower
