hello all ,i have recently upgraded to 4 pot front brakes on my 94 wrx,i was wondering if it is worth upgrading the rears to 2 pots as i have read a few people saying on here that it is not really needed as it does'nt give much improvement over the standard brakes,just wanted to know what peoples experiences and thoughts are,thanks

ive just done the same. do you have any pad overlap on the disc?

Don't think it makes much difference. I went from front 2 pot to front 4 pot,massive improvement and left the rears.
Went to an Impreza that already had the 4pot/2pot combo and didn't notice much improvement.
Aesthetically though it does look quite good.

HI
It does make a difference , but as always it depends which pads you have fitted.
If you fit the 2 pot rears the car will not nose dive so much under hard braking , as the rear brakes work better it keeps the back end more planted on the road , so will be more stable braking going into bends , having the rears working better also takes some of the work off the fronts , so you you don't overwork the fronts.

This is why they fitted 2 pots to the rear of the classic Type R , as it was made to go rallying

You should get no overlap fitting the 2 pot rear calipers , unless you fit them to the original 266mm discs , you have to fit the 290mm rear discs that they were designed for

Also think about getting the brake bias valve removed.

Mine was done five years ago, stops better and doesn't nosedive.

Ian, notice I have the Subaru 4 pots on the front of my 1994 and the standard brakes at the back and worryingly it locks the rears before the front. Could this be from the brake balance being upset by having the 4 pots on the front?

Hi
Its more than likely a sticky caliper , probably a rear one , if the front brakes were too good , it would lock the fronts not the rears.
Check the rear sliders and pistons are free to move

I installed Subaru 4 pot front brakes on my WRX and had V3 STi rear brakes on. I drove around like that for a while until I decided to upgrade the rear brakes. I installed Subaru 2 pots and there is a significant difference. The rear end doesn't come up as much and the car does feel more planted. It's definitely worth it to upgrade to the rear 2 pots.

The 2-pot extender bracket kit, which you'll need:

I have this exact kit - from that same vendor - on my 4 door STi 5 for my own 2-pot/290mm conversion. Been on for around 3+ years -- no sign of brackets snapping, or anything like that lol

Thanks Ian, I will have a look.

My thinking was larger piston area of the 4 pots requiring more pedal travel compared to the standard callipers so more brake force is being applied to the rear if that makes sense

Another rip off copy of my design we can supply you an original kit

Were you the original person that 'blueprinted' the design then?

Had no idea. I assumed it was a common kit made by some 'big' company, or somesuch.

Feel a bit 'guilty' now.

Yes it was my design I came up with a few years ago , along with the thicker handbrake shoes
