[QUOTE=GETAGRIP]Brendon,
In terms of calipers that fit under the 16's, I know that waaaay back, Duke Ting ran an AP caliper that 'just' squeezed under a 16" - 5 spoke Suby rim. One of the ole' timers on here might know the details.

I am going to talk to Michael South from over east. He put some massive brakes on Tony Sullens car for Targa Tas (i.e. under 16's) and can hopefully point me in the right direction.

The fact the rotors are munched does not concern me too much. I spose it is a compromise. Figured if I go large then hopefully there is something out there that will last a little longer than the DBA stuff.

They look like my rotors, copped an absolute hammering on the weekend. They got that hot it turnt the red writing 'Brembo' on my callipers to black and its not changing back.........I am running EBC reds on stock rotors. Time for rotor upgrade.

Yeah, the red Brembo writing on mine went black (or extremely dark red) ages ago...plus the gold colour also darkens...and no, they don't change back.
I remember the Brembos on Dean's Subaru Motorsport Targa West car last year were brownish rather than gold.

And Brendon, I suggest you talk to MMS if you want to get some upgraded calipers...as per Dean's rally car.

This is interesting.

I should have looked at the colour markers on mine last night. I found my DBA4000 / Ferodo 2500 combination crap at Collie. Fine for a couple of laps only. When I came into a corner at nearly the top of 4th and the brake pedal did nothing, it was quite a brown moment. (Must say I haven't done long track for a while, so I was braking more than normal on the first few laps which cooked the brakes early in the day). Because of this, I was looking at the 3000's.

Interesting that the 3000's were braking fine, but chewing rotors. Guess its a compromise one must take.

Is there an alternative rotor to the DBA that might hold up better?

Have you upgraded your fluid?

[QUOTE=nauli]Have you upgraded your fluid?[/QUOTE]

Fluid changes are happening shortly (as I can't remember whats in there at the moment :eek: ). To be honest, I think that played some part in it, but pulling into the pits with the brakes smoking away makes me think I cooked them early on.

brembo ap? :)

Scuff the rotors, do a fluid change and throw in some pagids. I've been running the oranges on factory calipers/rotors at wanners till they were glowing. I'd get 10 laps on long @ wanners before they'd begin to fail. (of course thats on the porka, but i think the pad material on 3k's are shitting themselves and filling your rotors - purely speculative of course)

You can squeeze 330mm rotors with AP or Alcon calipers if you want to go the whole hog.

Dont bother with the homologated STI brake setup ala Dean Herridge's car as a) it'll cost a bomb b) it designed to fit under 15" rally wheels so you'll be losing another 25mm of rotor diameter.

My first step would be to get the rotors skimmed, flush the fluid and throw in a different set of pads. I'll be ordering some Galfer 1065 pads later this week. They're meant to be very good fast road/track work pad which work well from low temps. PM me if you want pricing.
