After watching this I’m thinking 235f & 255r then try a 265r next time round.
I would go a 245f if there’s enough room. Test driver notes that the wider tyres have a better ability to deal with heat too.
I used to run a 225 square set up on my Golf R and I know that was limiting grip.
As for brakes, I just can’t see stock rotors being up for the abuse I’ll give them them and last thing I want is to leave a track day with stuffed rotors or suffer more fade than necessary on the day. Brakes Direct in Qld offer DBA T3 4000 rotors for $180 each which is a bargain really. Seems there aren’t too many after market options for a reasonable price.
