What BMC with this brake setup?

[kingJurzy]

I have a 98 S14 am currently running Q45 brakes up front and stock brakes in the rear (going to upgrade to Z32 rears in 2 months). The pedal feel is super spongy and has the OEM stock BMC on the car.

I found a deal on Evo 8 Brembos and have ordered all the necessary parts to install them on the car but the BMC. I don't know what size to purchase so any help is appreciated.

With Q45 fronts, you can keep the OEM BMC, but you have to adjust it. Google searching will provide you the answer.

No idea about the Evo brakes, but when you install those, I'll buy those Q45 brakes from you. Straight up. Sell them to me.
