Track brakes
#21
There is a corner that's so scary at HHR and MSR-H that I have to put my left foot over my right to hold my right foot down on the throttle becuase my brain tells my foot that "you should really lift, this is dumb". It's pretty retarded to do this at 120mph+, but this is what makes us men.

1.8 brakes are woefully inadequate for 200+whp cars that weigh 2500+lbs. I ran through a brand new set of XP10s in 5 sessions at Laguna on 1.8 brakes. The caliper cannot press evenly on the pad, which causes hotspots, accelerated wear, and warped backing plates. You really should reconsider a Wilwood kit.

Could I do just the fronts to start?

That's all i've done through the kink anyway cause i'm a big chickenshit. Lol. Still have about 6' of run out left and have yet to stay flat through there. Running right behind an STI as we went through at 105+ and him spinning right in front of me didn't help build confidence either. Haha
I am not sure what your suspension setup is, but I don't doubt you have plenty more to go! That's about the same speeds I take (I am more in the 100-103, because I DID spin out at the kink before) with my 205 AD08/star specs.
I know I have said it twice now, but the 3rd time is a charm. at your power levels, you realllly gotta step up your brakes. If all you can fit in the budget is a front BBK, then do that and get the rears at another time. if you have adjustable shocks, you could probably stiffen up the front a bit to keep more weight rearward, but I don't think it matters really since you aren't going for laptimes or anything.
Have fun though CMP is AWESOME!

Exactly what the kink at CMP is like. Last time I was there I was running pretty consistant 105-110mph with just a slight lift before turn in, flat with that car (253whp 277wtq 2900#) would be 120+. That's the reason I keep running CMP when most of my friends have moved on to VIR, gotta overcome the fear.
Also, run VIR, it's ------- awesome. I was just there 2 weekends in a row. :v

SM betas always comment, "do you really need all that brake? What a waste of money."
Yes I need all that brake
No, it costs me less than half as much in wear items at double the power of your car.

You can't be scared of the kink man! It will bite you in the *** if you lift or even worse brake at the wrong time. I had an Evo pass me last year, just before the kink. Like slow motion I could see him transfer weight and begin the skid. He spun a few times and went off track. Luckily he did not hit anything, but somehow managed to mess up one of the front fenders.
My first track day EVER was in a FFR 65 roadster at CMP. That was overwhelming doing the kink at 120mph! I wish I had pictures of my white knuckles that day!

After torching a 50% set of XP12s on Saturday, this was what I did to a fresh set of XP10s on Sunday at Laguna 3 years ago:
This is the outside pad - the stock caliper fingers pulled in on the top and warped the backing plate
This is the inside pad - single factory piston pressed on the center of the pad and warped the backing plate
The issue is caused by the factory caliper, not by the pad, so the only way to fix it is to swap to a different caliper.

Yeah, you can start with the fronts. The prop valve becomes more important, though.

The talk in this thread of stock 1.8 brakes being inadequate for 200whp on track has me slightly worried. The only thing keeping me from getting reeeeally worried about having spec'd inadequate brakes for my build is the thought that I'll only be running 185 section AD08s. Can anyone put my mind at ease and confirm my thoughts that I simply won't be able to generate enough braking G with my ghey-section tyres to drastically overheat/taper/f*ck track pads in a 1.8 setup?

I ran 205 AD08s with carbotechs and did not do any warping/welding, but I did get a slight taper on the wear for both my last sets.
