Randy and John – I would be up for helping you all out with the rules for the McLaren series. They won’t vary too much from the Group C rules other than a stock 15″ rear wheel. The guides are usually open as well as braid and wire. Motors are limited to dark orange end bell 23K Slot It motors and tires are usually Slot It. This limits people having to buy too many other tires to try out. The shore 30 tires work well and in the cooler temps of January and February the light cars will work well with shore 22’s. There will need to be a weight limit as well.
I can do a first draft or leave it to you two and then help you edit it. Let me know.
