I was looking at the Mk 4 Roadster and am comfortable with how I will fit in it. Then, I noticed the 289 USRRC and really like the opportunity to make a tribute car to Ken Miles' CSX 2431. However, the FFR literature refers to the 289 USRRC/FIA as the 'smaller cousin' to the Mk 4 or something like that. Does the 289 actually have a smaller cockpit?

Thanks!
