the eliseparts 4 pots dont need a bigger brake master cylinder and will also fit on an elise with the 295’s if you are running a wheel that can fit them in like rotas. can also split
the front ones only fit the elise parts 4 pot calipers as far as Geary from elise parts told me as i had to buy new rotors to fit the 4 pots. I can only really split it front set up and rear set up.
