I beg to differ on the brake bias point. Sure it's different but z32s would'nt be such a popular upgrade if they didn't perform. Brake bias according to another post on stock brakes is about 70/30, Q45 is about 68/32, and Z32 is about 66/34. Yes the bias is different but you have to remember that stock brakes are pushing two pistons in the front, and two in the rear, while Q45s use four front, two rear, and Z32s push eight front, four rear. I'm no expert but I cant help but think that the reason for less bias up in front is due to the fact that since there are more pistons to do the job, less bias is needed to see equal or better results than a Q45 set-up, giving you an overall stronger braking system. I run R33 GTS-T brakes with a Z32 BMC and I love them! No problems whatsoever.
As far as what brakes are right for you, there are many factors that determine the perfect choice for YOU. Both will caliper upgrades will provide you with good results. It depends on how far you will be going with your driving of course that may determine the better choice. You may need to get larger wheels for the Z32s if you're running a 15" wheel but if you plan on getting wheels later, the Q45s stock and wimpy appearance may not compliment your wheels like Z32s will. I'd just go Z32 but only you can decide what is most important.
