My 4 pot APs have turned up today (big thanks to alyn @ AS performance) but I have to confess to being a tart and buying them for cosmetic reasons.

I have 362mm 6 pots on the front and am thinking that the standard rear disks just don't look big enough inside the 18 inch wheels.

Is there a company who can convert the rear brake set up to using a bell and disk and somehow retain the handbrake, which I assume is the problem.

anyone seen anything?

I have seen it on one Evo 6 !

You need to have a handbrake conversion and run a seperate h/brake caliper as well as the rear 4 pots.

He said he'd converted it from the escort cosworth rear AP kit's the do with that set up .


Looked trick , maybe have a word with AP Racing

Adamantium : AP Racing don't do anything, the bell would have to be cast iron for the handbrake drum and would cost too much to be worth while. At the recient MLR brake test the rears only reached around 100°c and the front more than 600° so the rear on the EVO are hardly doing anything. (I did mine for the same reason as you ;) )

TurboTom : even more expensive and complicated !

neverneverman : you must have something wrong this should not happen, it dosn't with mine and I have no ABS

They may have made something bespoke for them with an AP Racing kit

wow, thats great help guys, especially Jez.

I didn't think the rears would be doing much, I just thought for cosmetic balance the rear disks should be bigger.

Is there no way of machining a standard rear drum/disk to act as a bell to support a replacable disk?

Probably too far fetched for little gain.

on another note, does the standard abs system cope with the uprated braking power.

On my 22B, it was easy to grab the front wheels with 330mm 6 pots, but that had no ABS. I am not sure how good the abs on the evo is, but I am glad to have it!

Don't forget if you put the calipers on a larger effective radius you will get more braking force. Over doining the rear will see you disapearing backwards into the vegitation .... :eek: The balance between front and rear is quite critical.

The ABS will not know any different, the limit to the braking force is probably the grip of the tyres anyway.

rears dont get more than 100 degree's :confused: :confused:

mine turn blue after a trackday and thats running 362mm ap's on front
If only they could set up their brake bias :D

On a side note - Iron bells are not *that* much more expencive, and really the only other option (short of an independant mech h/b caliper).

But yea, over braking the rear to look cool = crashed (or stunt) car
