Hi it's a bit of an art to get the correct balance.
Example my GT40
Front runs Ap racing 4 pot calipers 268mm disc 225 tyre and is 40% total vehicle weight
Rear runs Saab 9000 turbo front calipers and a 265 tyre on 60% of vehicle weight - sorry cannot remember disc diameter
Using 0.625 masters on both I was locking the rears first - even with the balance bar cranked over
Now run 0.75 on rear and 0.625 on front - no boosters 6 to 1 AP pedal box and it is good once warm - until then I still seem to get more rear bias - probably need to adjust that out on the pad hardness.
Wilwood normally has a sizing sheet on their website that allows you to plug in all your dimensions and they will come up with a good "first fit" - it will work but need not be the best attainable
