Perhaps I should add a little more info on what I’m thinking to get any thoughts. We run the Bridgestone YHC. Typically at our track it’s about 13-15 psi. I am using DWT MAG LV. My kid(driver) is 5′ and 125 lbs. Going to mount the seat as far forward as possible, bottom flat and even with the bottom of the frame rails. No crossbars. Rear ride height set at max. up. Rear axle is soft. Front set up neutral. Our track is 7/10’s of a mile., long straight, 2-3 sweepers and 2 tighter (slower) corners. Gearing will start around 15/57. Thanks!
