Rob just uploaded a short clip of me passing on Buttonwillow 18CW last Saturday. His car is a mostly stock 95M Edition, on 205 Z214 C30's (very hard). I think he has a Goodwin intake and maybe a header, 115whp perhaps and carrying a passenger. I was right on his bumper exiting Cotton Corners, lifted a tad to make sure he wasn't tracking right, then floored it to get past. That was my out lap so I pedaled a bit through Riverside and missed the apex. That was my first time ever braking for Star Mazda on 18, very conservative so he closed on me. Exiting Star my tires are now warm enough and simply motor away like an S2K. The car feels fast but that shot exiting the esses really brought home the difference. Now I now why William was a bit bummed after I passed him. Sorry!
Second clip is from William's 99 N/A. His car is a bit faster than Rob's.
Incidentally, Rob spent quite a bit of time on the first iteration of this project car. I owe him some seat time in it so he'll be able to humble some more expensive cars soon too.
