I am running a vintage set of Recaro Profi SPGs, with custom bases because there isn't a bracket for an early car.
I have my rev limiter is set to 7500 through an MSD, and I think you can get a dizzy rotor for 6800 or 7500, if you want.
Those will be some fun tires for a first time, forsure. You only need power steering at low speed, once you reach 20mph you wont be able to tell the difference, if you have it or not.
