BRZ Aftermarket Sources

The WRX uses a 295mm vented rotor, and I wouldn't be surprised if the AS1 does as well. I also know that the 4 pots don't suffer from mushy-pedal-syndrome when paired with a stock WRX MC which pushes the same sliding calipers that appear to be on the AS1. To be fair, this does nothing to address rotor size, but if people are all that concerned with actual braking force, this may be a slightly more cost effective option.

True, and yes the AS1 uses the same 295mm rotors.

But I'd only suggest this for looks. As Vito pointed out, you are not increasing the size of the rotors (to some extend they would help with fluid fade.. SLIGHTLY... and only for an extra lap or so..), and the stock sliders will lock up the tires just fine so there is no shortening of the braking distance to be had here with slamming on the brakes.. but you should get better modulation and pad wear. With better modulation comes the ability to more easily find impending lockup which will outbrake ABS (slightly) assuming the ABS system isn't tuned overly agressively.

Perhaps Legacy GT Front rotors and sliders as a more effect option?

Just looking over the OEM Subaru brake options at http://forums.nasioc.com/forums/show....php?t=1265631 , and it appears that they mey be the best "bang for your buck" solution. 2005-2009 LGT that is.


Edit:

Possible vented disc solution for the rears, stolen from the same thread:

290x18mm (170mm parking brake)
290x18mm (190mm parking brake)
290x18mm (2010+ Legacy GT)
This is a new rotor size for Subaru (in the US anyway). It uses either a 2-piston opposed caliper or a 1-pot slider. The 2-pot will not bolt up to other Subarus without something like the Kartboy brackets or having a new backing plate pressed onto the spindle. There are three versions of this rotor, one is for the regular 170mm parking brake, the others are for the sti 190mm parking brake in both 5x100 and 5x114.3
Applications:
05+ Legacy GT (1-pot)
06-07 WRX (2-pot)
SVX (5x114.3) (only in JDM-land)
Some older non-us spec-b Legacys and wrx/sti models (see rear brake redux)

Note: The LGT uses a different brake line than older Legacies and Imprezas. So I think you need to grind down part of the caliper where the line mounts to get it to work on an Impreza. The LGT lines are a different shape and mount and a different angle and you can't use them.

I do both. I own 3MI Racing (designing tailored/custom Subie parts since 06) and also consult at Volvo Powertrain in their performance and emissions group.

I a long time Subaru head (though use to have an old SR5 too, twas stolen...to those Toyota guys) and know/work with several vendors or give input on ideas and projects. I then do my 3MI Racing stuff which is more engine oriented in block, heads and subsystem design work. But I'm finally coming out of the tailored market and going mainstream with a few engines...hence my website now being under construction.


Still waiting to see if Quirt and Bill will let me know about fueling.

Nice link

Was just going to post that (the LGT rear info) but then I did the quick math.. the 290x18 is stock on the AS1 using the Legacy GT 1 pot slider Otherwise that would have been the ideal rear upgrade for cheapness since you wouldn't have to deal with the parking brake crap.

The front LGT upgrade definately sounds interesting although I suspect Subaru would have tried that and found the front bias to be too much.. or maybe originally it was WRX all around and fixed the front bias issue with the LGT rears.. either way just upgrading the fronts to LGT spec may be enough to offset the bias enough on track to hurt braking performance... someone will have to test.

If you are limited by the AS1 stock brakes but want to save some money perhaps STI rears and LGT fronts would balance out pretty nicely..

edit: last sentence was totally wrong, was processing too many things in my head while typing lol

The likelihood of COBB doing anything for this car is pretty slim. They completely back ed out of the non-FI marketplace a couple of years ago and I just spoke with Gary while at SEMA about support for new non-FI cars and he indicated that it would be hard for them to justify getting back into that game. That primarily applies to AccessPORTS, btw...I'm sure that if current WRX/STI hardparts are direct bolt ons, then you'll see some crossover.

All of the usual suspects will have parts out quickly...AEM/K&N, Perrin, Whiteline, Cusco, GTSPEC, Invidia, HKS, Greddy (obviously), Brian Crower, KW, Tein, Eibach, and Hotchkis.

And Robispec? Really, how is that guy still relevant? He was terrible to deal with seven years ago when my friend and I were giving him feedback on his early KW spec Evo kits.

^^^I was figuring with how the market is so hyped about his car, that Cobb would be back into the NA market...sounds like I was wrong.

perrin and ams please!!!

Yea, I was hoping they would be able to apply their skills to this platform too. Maybe there will be enough call for an AP, but I doubt they will be able to make more than 5-10hp from a tune and that is hard to justify charging the $495-595 MSRP that they would need to charge for the AP to cover expenses.

I hope Cosworth is planning on doing some n/a parts and even full packages for this car, they have worked alot with subaru recently on the wrx STI. They have built some great n/a motors.

Thanks. That's the list I was looking for. Greddy's already shown a modified FT86... does that mean that frontline suppliers might find themselves in receipt of preproduction BRZ' before too long? Or is Subaru not so inclined to front load the aftermarket?

Same car man. Any parts developed for the 86 will work on the brz

Same car different bumpers (and cosmetic crap)

This will be the first setup I test, as everything needed is sitting in my garage.

Good thread.
