What brand of brake callipars are people using for Rallys?  Comments on Minisport 4 pot variety please.  We are using 13" wheels.

First thing to check is your rules and regulations. 
 

what they say about brakes?

 

then there is what type of rallying is it? Dirt it tarmac?

 

i would not get the MiniSport ones but look at the KAD ones of whatever size you want.

I use the minispares 4 pots with the carbon metallic pads in my track car. It's not a lightened shell by any means and is 180+ go and I have never had brake fade. They really do work well on whatever track I have been to, they give me a lot of confidence to push it.

I had standard 8.4 discs under 13's and swapped them for Cooper 4 spots which are suspiciously the same as minisport 4 pots. 

Absolutely no difference in stopping power between the 2 sets of brakes.

Maybe a harder pedal with the 4 spots.

Yes my 8.4's faded big time on track days but that was due to standard pads.

All I did was stand harder on the middle pedal.

My 8.4's would lock up easier on tarmac than the coopers but I put that down to some hard older Yokohamas.

Got Nankang AR-1's all round now and they grip very well turning pink into purple.

In my honest opinion save your money and put fancy pads in for track days.

What I should of mentioned is the weight saving between the cast iron standard calipers and the alloy 4 spots.

5.4 kg in favour of the alloys.

The vented disc adds a kilo back on.

This is hard to ignore in a weight saving program.

Works out at $213.00 AUD per kilo.

Halve that figure to convert back to pounds sterling.

As a comparison carbon bumpers work out at $217 per kg, boot and bonnet at $281 per kilo.

If anyone is thinking of a carbon fibre steering column surround as a weight loss item it works out at $21,875.00 per kilo saved.

You only save 0.032 of a kilo by the way.

The lighter brakes improve unsprung weight which counteracts the weight of the 13 inch tyre/ rim combo.

I've got the KAD lightweight hubs as well which is another 2 kilos.

Depends on how serious you are I guess.

I have to use the 7.5" brakes on mh historic rally Cooper S because it must comply with FIA Gp 2 regs.
I fit the best quality discs with the Carbon-Metallic pads as supplied by Mini Spares. Brake fluid is AP600.
Never had any issues even on long tarmac stages.
The car weighs around 720kg in full rally trim with c.110 bhp.

I'm quite fed up with the EBC Green Stuff pads in my 4 pot Metro Turbo calipers on vented discs. Brake force not lineair with pedal force. My MGB V8 with Princess 4 pots  had the same issue, swapped for Ferodo DS2500 which work very well.  Anybody knows if these DS2500 are also made for 4 pot Metro Calipers?

Use will be fast road / hill climb / trackdays

The best place to buy brake pads is from 'Questmead Ltd' who are in Rochdale.

I would suggest that youn try a Mintex 1166 or 1177 competition pad. I used the 1177 in a Rover 214Si rally car and they were fine. 01706 363939 is their number.
