question about tires, brakes, locking up, kinda all in one
i just upgraded my front brakes to z32 30mm w/ fr sport drilled slotted rotors and hawk hps + pads... lots of braking in front. i have 225 series tires up front... little tires...

when i took the car out to bed the new brakes, i could hardly touch the pedal without the brakes locking up. even just the slightest tap on the brakes would completely lock them up. so here's my questions:

1) if I put a 17/16th BMC will that help put more brake bias to the back and maybe ease up on the brakes locking up?

2) then, if I put bigger (Altima) slotted drilled rotors on the back with the same HPS + pads will that also help distribute braking more and help prevent lock up?

3) lastly, if I put some bigger and better tires all the way around, will that also help quite a bit? I was planning on buying some Dunlop Star Specs... 245/40/17 (front) and 255/35/18 (rear). or should I try 255 all the way around?

the car is solely a weekend warrior track day car

thanks in advance!

I have my first track day in 13 days and trying to be ready for it.

FWIW: I already have the z31 brackets, rear rotors and pads, just haven't had a chance to pop em on yet. and I've already ordered a 17/16 BMC. I'm just hoping a combination of tires, bmc and better rear brakes will fix the lock up issue.

Switching to the 17/16 BMC alone will solve most of the locking up issues.
