Running the C4 at Mid Ohio with Cincy SCCA TT. Was breaking in new set up - Forgeline GA1R + Falken 660s in 315 square, hawk DTC 30s. Had some braking issues, and was off my game after a long week of business travel / being up until 1 the night before getting the car together. Managed a 1.45 on the club course, will look to improve on that considerably at GridLife next weekend. Thank you Cincy SCCA for the awesome event!
