Josh's Starlet Mini (200+ HP ATW) had traction and handling problems with 13" wheels and A048Rs. So he dumped them in favour of 10x6s with A032Rs.

So He Under Tyred a 200+ HP car to Cure a Problem with the Subframe, Chassis setup ?
Gee, Alarm Bells Should Be Ringing There Don't you Think!!!!!
By all accounts (and my sotp recollection) 13s just didn't suit it. It used to change lanes in the dry when you gave it the berries.
I agree about the subframe, but no I didn't design it (and I plead the 5th amendment on any input I had there).
I reckon a lot of the problem was/is that it is overpowered. with 150HP or so at the treads instead of 200+ it would be much more manageable.
Been a while but thought I'd chime in here for anyone who reads this.
The car could run on variable boost anywhere from 12psi-22psi ranging anywhere from 150HP to 250HP and I spent years fine tuning the suspension, alignment and bracing the subframe where needed. There was no subframe/chassis 'problem'
I've had multiple minis ranging from 10x4.5 to 13x7's and in my expexerience a mini running 10's will handle and drive better than a bigger car and with an A032R are not 'under tyred'. You save 5Kg per corner switching from a 13" to 10" setup. That's 20Kg of unsprung weight.
Nick Swift even commented in his last goodwood video running the Longman Clubman (which must run on 12's) that it doesn't handle as well as a mini on 10's. The extra sidewall is part of the suspension package, ads compliance and reduces weight.
