Can't afford AP brakes. How about "cheap" blanks such as [ame="http://www.amazon.com/Centric-Parts-120-47021-Premium-E-Coating/dp/B000IY4A0Y"]this[/ame]. Paired with some better pads?

It's also what we recommend to our clients who don't have 2k to spend up front on a BBK; blanks and upgraded rotors do the job just fine. When it's ready Here's teaser |

If I were to illustrate a slip angle on a graph, with the peak grip coming at 6 degrees of slip and I have 2 drivers that turn identical lap times but one runs on the front side of the curve (5-6 degrees of slip angle) while the other operates on the backside of the curve (6-7 degrees of slip), who is the better driver and why?
And yes, there is a right answer. Hint and cheat: It's in the Ross Bentley "Speed Secret" books.

The lesser angle is the winner in a "general" sense, because he will grease out the tires slower. |

The other half is that any driver operating on the wrong side of the slip angle, even by a little, puts him too close to the "edge" leaving nothing left in the tire. If he needs to make a sudden change when he's committed to a corner, he cannot without great difficulty and penalty. There will be a quicker drop off of traction and this will result in A) any mistake will be amplified resulting in greater time lost and/or B) a mistake will lead to an "off" or incident. As a driver, I am extra cautious when racing next to drivers who drive like this and it's easy to spot them (they're usually in the dirt). OK Mike, I'll stop terrorizing your thread now.

background
My HPDE experience consists of just 1-2 events per year for the last several years. I would run my S2000 100% stock, except for Direzza SS Z1s and Carbotech XP10/XP8 pads. All fluids 100% stock, nothing special. I would usually run in one of the faster groups and never had any overheating issues. question I'm taking the BRZ to the track for the first time later this summer, to VIR (first time there) for a 3 day event. I had just been planning to slap on some Carbotech pads (still using the OEM tires) and hit the track. Is there anything else I should do before hand? I ask b/c I never had any issues doing it this way with the S2000 (I realize they're similar cars but obviously not the same). Typically I would bleed the brakes and change the oil but both are quiet fresh at the moment already. Thanks Mike

I'd recommend changing to RBF600 brake fluid, and your preferred engine oil, not because the fluids in your BRZ are not fresh, but because they're not really suited to hard track duty. Remember that this car has significantly softer springs than the S2k (stock vs stock), and that you need to ease the car into the turns, rather than being able to manhandle it like the s2k. |

Should we wait for an ECU update before taking the car to the track? Wouldn't want another siezed motor.
