Not much to update on bodywork progress... thought I’d share what I ended up doing for brakes. After reading this long but very informative thread on proper brake sizing (
https://www.pro-touring.com/threads/...Tobin-of-KORE3), I had Ron Sutton help me run some brake torque calculations for me to optimize the braking system for the Nova (I know Sutton’s reputation is trash right now due to recent events with his company, including Greg Weld’s debacle with him, but I found him helpful and knowledgeable for this exercise).
He ended up recommending a Wilwood package - Aero 6 calipers for the front with the larger piston sizes to provide a greater piston area and Superlite 4 calipers in the rear, again with larger piston sizes to provide adequate piston area). We went with the Superlite 4 calipers in the rear rather than the Aero 4 calipers, which would have been a better cosmetic match to the Aero 6 front calipers, because the piston sizes of the Aero 4 calipers weren’t a good match to provide adequate and balanced braking. We were targeting around 3000# of brake torque when equipped with street pads and 3500# of brake torque with track pads, each with a 70/30 front to rear bias. The piston sizes for the Aero 4 calipers were either too small or too large to achieve our targets with adequate levels of brake torque.
I went with 14.25” front rotors and 14” rear rotors, drilled and slotted, in Wilwood’s Spec-37 material. With Wilwood BP-10 street focused pads, a Wilwood 7/8” manual dual master cylinder, and an adjustable proportioning valve, this combination results in approximately 3100# of brake torque in our desired 70/30 bias. That should be more than adequate for the street with 255 width front tires given the Nova’s lighter weight. For track days, I can swap in BP-20 track focused pads, which should, with their higher coefficient of friction and the higher operating temperatures on the track, increase brake torque to around 3500# at our 70/30 bias.
Attached are a couple of photos of the front rotors and calipers - they’re big, should work awesome and will look great behind the wheels!
