Do not know much about on road cars. The only nitro on road I have is and Ofna Colt F1 that I have only run once. I have a couple electric open wheel cars manly because I like F1 and GP racing. Then I have my Mini-Z F1’s I run on my RCP track in the house. I have been told HPI makes very good on road cars. Might do better to go to the nitro on road car thread. Here is some of my Mini Z’s and part of my track, as I do not have room to set it all up.
