What do the engineers deem as a "20% increase in braking capacity"? Does it have to be an increase in rotor/caliper sizes front and rear? or just in the actual braking performance of the car? Surely braided brake lines, good slotted rotors and pads all round should give you a 20% increase in performance?
Also, would it be worth looking into the brakes off a 380? I'm not sure if it was the triton or magna crowd, but I remember someone looking into adapting the 380's calipers and rotors to suit their cars.

Guys I know this may well turn out to be something completely custom, I'm a qualified mechanical engineer remember.
And the next person who says to me "A good set of slotted rotors & pads should be all you need" is going to get slapped. Because it's clearly fking not the case! I've worn out a 330mm big brake kit rotor & have been on the phone to a dozen smug brake 'experts' who have all been telling me "A good set of slotted rotors & pads should be all you need"
I have asked the RTA engineer to specify exactly what the 20% increase relates too. He's 'faxing' me (yeah I know... faxing) some documentation tomorrow. It's to do with surface area, but there is also a fluid volumes requirement on top of that from what he was saying.
Just to refresh memories, this is what I've been using (and have now worn out.) Gotta remember & I'm carrying more weight than most FTOs & have more than twice the power. I hit much higher speeds on the track, coupled with some fairly aggressive pads, I've gouged out, cracked & fractured the discs pretty badly.

They do look like a pretty sh*t rotor though, not very thick for a 330mm?
How long have you had this set on for? Any after pics

Been on for about 5 years. Yeah they're only 24mm thick.
Ok, so today I'm going to visit wreckers! I'v been speaking to some Mitsi parts gurus this morning.
Apparently the Evo 5 hubs fit into the FTO with no mods... and onto a Evo 5 hub, I can direct bolt on the 4 pot Brembos & 320mm x 32mm rotors that come standard on the Evo 6.
The guys in the pommy colt club have been doing this conversion for years.
Interestingly enough, the Evo 5 lower control arms are also interchangeable with FTO. They're alloy & supposedly stronger & lighter than the steel ones we use. Also have mount points on them for a GPvR style swaybar.
So, i'm off to SSS this arvo with some FTO bits & will do some comparisons. If all of the above is true, then techncially its a 'factory' upgrade!

Massive WIN

Will be watching this thread with interest!
And the EVO V hubs are 5 stud, and 69mm centre bore, more WIN
24mm, really a bit thin for a 330mm rotor, should be minimum 28mm for that diameter, but they did last 5 years, so...

Yeah it'd be intresting for us all to be able to do this 'factory' upgrade!

Wait, did you need a 69mm centre bore? coz fto's have 67.1mm...

No, FTO is 69mm.

Im confused... Are you referring to the one that sticks out of the rotor and secures the wheel?
I distinctly remember being pissed for buying a Nissan spacer with a 66mm centre bore, and not being able to fit, resulting with me having to buy another set that suits Mitsu which had a 67mm centre bore... (correction, i think it was 67mm without the .1

)
Well mine has 67mm... at least the part that im talking about

you're right, it is 67. I was looking at the DBA catalog, lists it as 69, should have known...

You know the annoying thing about this, I've been looking for replacement rotors going off the specs from the DBA catalog
Yeah I know, stupid me right
I'll check my 'cracked' DBA rotors later and see if they are actually 69 or 67
