Welcome to the LegendsRacer family!
There are plenty of guys your size, or larger, racing these little cars. "Comfortable" is a relative term. LOL!!! You CAN and WILL fit! There are some tips and tricks in some of the old threads as to how best to make it work for you. Look through the old threads or do a search. If you need help, message me and I will find the threads for you.
Regards,
Steve
