I see those front Big Brake Kits have the same size rotor as my sport brakes have now, but with two pistons. Some kits mention adding sport brakes in the rear, which I have already. It would seem my brakes would already have the thermal capacity of these kits and be far superior than standard 1.8 brakes, but I DO trust Andrew's opinion. Maybe I should start with some fresh fluid and some XP-10s or XP-12s and see what happens before going BBK.

Agree- I'd just upgrade fluid and pads and then wait and see what happens... as you get faster you'll eventually need larger brakes.

That said- a bbk for the front axle is probably pretty cheap (that's all you'll need... my bbk has sport rear discs).

Adding to the -BBK is worth it side. I'm at 145ish whp. With stock 1.8 brakes, DTC60s and running at or slightly better than SM records, I was going through a set of pads in a weekend more or less. Found a deal on the 11.75" BBK, upgrade the rears to 11" rotors- pad life is way way extended. And ****- dat pedal feel.

I couldn't imagine having 200whp and not having bigger brakes. I would never feel confident going into a turn.

It was amazing compared to my old spongy 1.8 front calipers. I wasn't afraid to brake later and later, and they inspired a lot more confidence. As a novice and still learning how to drive on a track it made a huge difference in my confidence.</p>

The powerlite calipers on the LBBK have small pads with limited pad selection. Fine for the rear but not for the front of a heavily tracked car.

This. Oy vey, don't get me started on the LittleBBKs. On the front of the car, they're a downgrade from stock.

Sport front rotors are 10.6", our BBK is 11.75"

Whoops didn't realize that!

All of our BBKs use four-piston or six-piston calipers



I disagree

So just your basic BBK would be enough with some DTC-60 pads. Can I leave my sport rears with XP-8s or go for DTC-60 there also? How important is the proportioning valve with ABS? Since I'll be needing new pads soon and my rotors are getting thinner maybe it IS best to bite the bullet now. It may be worth it just for the confidence it may give me.

If you like the XP pads, stick with those. We don't include pads for that reason - it allows you to pick. I like the DTC-60s for their price and characteristics, but I've used XP12s in the past and they are good pads if you are OK with the cost and finnicky break-in.

The base kit is a perfectly competent BBK, yes. My black turbo racecar ran DTC-60s in Dynalites on straight-vane 11.75s for years with pretty good results. I would typically get 2-3 days out of a set of pads and 5-6 days out of a set of rotors, but that's in a 350whp car going 8-10sec under SM record. I think the Dynapros are a worthwhile upgrade for everyone, and if you struggle for rotor life, the directional rotors will help with that.

off-topic:
I do. I like it. Just think, very stiff porsche style pedal. You got a few options:
1) 949/Wilwood 1" with the 99 booster (sealed).
2) 949/Wilwood 1" with 01+ style boosters (non-sealed). You will need to figure out a way to seal the booster. I guess Silicone would work, or if you can find an gasket/o-ring? I sent Emilio an e-mail a long time ago about how he got this to work on crusher...but he didn't share .
3) 929 (the car) Master cyliner with 01+ style boosters.

Is it worth it? I think so. The pedal feel is stiff and very short travel. Your choice of booster, overall grip, and brake pads will determine if it increases effort compared to stock or not.

With that said, I did it because I plan to move to a BBK. That's on the back burner now for chumpcar.

1) What is the difference between the Dynapros and Dynalites?

2) Do the directional rotors last THAT MUCH longer to justify $150 premium? I could see on an enduro car but for an HPDE car are they worth the difference?

3) I like the lower cost on the DTC-60s, but could I drive them back and forth to the track? Local track is 40 minutes away...mostly highway.

Most of this topic is answered in the first post of this thread and a couple subsequent posts: 4 Piston DynaPro caliper upgrade for almost ALL Big Brake Kits

As long as you drive accordingly, knowing that they don't have much bite when cold (don't tailgate people, drive defensively, etc.) you can get to the track just fine.

Cobalt pads might be a good choice. I know from just taking a quick trip up the road that they have plenty of bite on the street.

I used Carbotech's on my last two Miata brake setups and was happy with them.

On the BRZ this time I'm giving the Winmax W5 pads a go.

Winmax is 2x-3x the price. They also scale the pricing increase for their pads linearly as performance increases, despite the relatively similar cost of production for pads across the line. It could be in part because the higher friction stuff is produced in smaller quantities, but the pricing structure still doesn't sit well with me.

If you're going to increase the budget, PFC or bust.

I've been told the Cobalts last longer. I dunno.

Carbotech does the same thing in regards to pricing vs performance.

And at least on the BRZ, the equivalent pads between the two brands are about the same price. I think the Winmax may have been about $20/cheaper for all 4 corners.

I just felt like giving something new a shot for the new platform.

only 2 types of racers out there. the ones that have tried the PFC's, and those that haven't.

once you try PFC's you won't go back to anything else.

All the talk of PFC is one of the driving forces in me saving my pennies for Trackspeed's kit this winter.

I really wish i had never put Sport brakes on my car.
