big brake upgrade

Hey all,

As some might know i'm seriously looking at getting a play car, most likely an ED XR6 (as it will also go on the track and down with fpvxrclub and down the shute at any events I can). However one of the first mod's I want to do is a sizable brake upgrade as well as wheel upgrades. I'm looking at 17"x7" or 17"x8" alloys (Holotype R from Speedy Wheels) but the brakes i'll be looking for would be something in the order of 4piston AP Racing calipers onto some ~345mm two piece discs (grooved and vented) up front and 300-320mm 2 piston rears.

Now what i'd hope to do, is use the front calipers (assuming they are 2 piston units) on the rear with the upgraded components on the front. Also potentially use the front discs on the rear. Can that work?

AU II XR6 - October 2001 ~ December 2002 - RIP
BA XR6 - December 2002 ~ Soon to disappear if Ford CRC can't fix it....

45,000km service coming up - and i'll be asking for a sizable list of fixes:
* Gearbox (3rd time)
* Steering click (5th time)
* Brake Shudder (2nd time, and has the applied "Fix")
* etc...

Re: big brake upgrade

Ed Xr's only came with single piston front and rears to my knowledge. and the caliper setup from front to rear is completely diffrent so they are not interchangable due to the hand brake.
You can machine your front spindles and fit twin piston EL GT fronts, but I have no idea what you cn do about the rears.
Speek to TIKFD6, as he has done an upgrade on his brakes.

Yeah i'm well aware of Kerry's brake upgrade, but i'm thinking upgraded on that again. So the rears have integrated hand brakes... Hmmm be interesting to see what to do about the rears.

Re: big brake upgrade

I understand Kyle Hopf, a Qld owner of a 10/11 second EA turbo, sourced 4 piston front calipers and slotted/vented discs all round. Unfortunately the article I have doesn't give any more details.

4piston are actually the warmed down versions... I was initially spec'ing out some 6 piston AP Racings and rotors that would require 18" rims.... ;-)

The more stopping power, the later you can leave it before the corner, the faster the track speed. :)
