well i do understand ur reasoning behind the weight transfer.
to an extent ur tyres play a big part in how long the transfer will last untill u regain controll. brand new tyres are great. but they tend to get you right on the limit and give u confidence when ur hanging right out sideways. be ready when they let go though. and try to run the same diameter tyre.
as i found out last fri at powercruise. i had brand new tyres on. my handbrake stuck on a few notches (forgot to tape up the button) and with the brand new tyres, gving me confidence in going faster, and lack of power to spin 3rd + the hand brake on, not helping things at all, i managed to find a plastic barrier.
i think that while u are still only a learner, as i am myself, try to stick to a smaller width tyre 235Front 225Rrear. and try to run the same diameter tyre that will give you enough grip.
what are your munji entry speeds going into high speed corners?
