It's a shame you are limited to such old Tamiya chassis because even though I have a couple of Tamiya cars, they are too recent to be eligible, and I don't fancy trawling eBay for an old chassis and NOS parts to get an eligible car up and running.
I can't see that an M-05, TT-02 or TRF418 would be an unfair advantage in their respective classes.
Will likely have to give this a miss, even though Cotswold is my "local" track.
