PGT 21104s on CB Design Steelies with Slot.It rear end is the ticket on the Monogram Nascars. I put a Slot.It rear end with 15" wheels under one of my Scaley '70 Camaros and the PGT 21105s fill out the wheel wells beautifully. The car is transformed - fast, smooth and easy to drive hard! I can't disclose my choice of motor or gear ratio yet - at least until after the Carolina Carnage event on Dec 1st & 2nd.
Thanks for the great tires Paul and the sensible numbering system you use to describe them.
