The second part seems to be less initial understeer.

How are you adjusting to rwd going ínto corners? The weight transfer and entry point needs be different on the MR than on most hot hatches. Not much sense in chasing the set up when you are adjusting your driving to the car or you´l end up chasing your own tail no?!

Yeah adjusting to the MR layout has been a challenge so far. With front crawlers you can just throw them in hot and if it starts to go wrong then mash the throttle to drag you out again.

I'm just being patient with the MR layout trying different lines in and out, braking techniques, trying to learn oversteer in a controlled environment etc. Still got lots to learn but it definitely takes more skill and balls to drive fast.

Back at Blyton again in a few weeks to hone it further, then to my home track of Oulton which will be the real test.

From the video the car setup looks good, going pretty much where you point it. You look pretty comfortable with it IMO

Tire diameter is a consideration when going up in tires. You never want to raise the car with a strut suspension with taller wheels/tires, then try to bring it back down with the suspension. The rear suspension on this car is already somewhat compromised. Angling the control arms up just makes it worse. Ideal setup would ride height as low as possible and suspension geometry correct.

However sometimes you can go up a wheels size because a better lower profile tire is available. The ride height doesn't change because of the lower profile.

Never use random alignment numbers from the internet. Tire size, corner weights, spring rates, swaybar, Aero, all affect alignment. Learn to use a tire temperature probe and dial in your own suspension.

Camber isn't for changing handling. It's for maximizing contact patch.

I have never had to run more camber on the rear of my car. It's not right or wrong. It's just what give the correct tire temperatures on my car.

Tyre temp on a given car is almost exclusively dependent on driving style. As such there is indeed no golden rule fitting all. Nevertheless it is véry helpful to have a well argumented point of departure.
