View Full Version : bira brakes?

02-19-2013, 07:47 PM
ok so i picked up a donor car and it has a "bira stage one boxter brake kit"
i have no idea what this is and apparently to access their site you have to pay or something?
does any one have any info on this brake kit and what exactly it consists of?
i could find almost zero information on this kit.
im 2 hours away from the car atm so i have no idea what is on it.
i basically would like to know if this is worth selling or throwing onto my car which has stock brakes and what the swap entails.

It's not as popular as it once was.

Here's the website for BIRA.


System 1

Uses Porsche Boxster 4-piston monobloc caliper over the 1999 Audi A8 312x25mm rotor. We have solutions to fit the '92-97 S4/S6, A4, A6, 1C, 2C(1), 5K, UrQ, '92-94' V8(1), VW Passat. Fits under 16" wheels.

ah thank you.
their site was confusing the hell out of me
so its basically like one step above an a8 upgrade?

Yea, it's an old-school webpage.

I'd say more like two steps above the A8 upgrade. You are moving from the stock calipers to a four piston/pot caliper.

oh well thats cool then.
the site says its for up to 97 but the 97 and 98 should be the same so i guess ill add that to my list of things to do

Yea, if you're not keeping the parts car, swap them out.

Plug and play.

Make sure to see if the rear brakes aren't upgraded (SS lines or something).

yea i think ive decided to part the donor car when im done with it as im too lazy to get it fixed up and sell it.
ill have to get the car on a lift and thoroughly look it over and see what else has been done that i can use
thanks for the help

I think there were some 996tt caliper/993tt rotor setups by BIRA as well! I have the info at work and will look it up tomorrow!

I think this is just the regular stage one with the boxtster calipers. I believe it's basically what ecs sells as their stage 2 bbk.

Boxter caliper with A8 rotor is one of the best brake choices for the B5 A4.

It's simple, easy, highly effective, and doesn't require upgrading the rears. I've tracked and pushed my Boxter/A8 setup quite a bit with great success. Far more consistent.
