Alloy 4 Pots - Again
Turbo Mini Forums

Apologies if this has been covered before but I've searched and not found a definitive answer.

I've given up trying to source fiesta kit for my 10" wheel conversion. I can get calipers but no one wants to sell me any with carriers.

So I'm looking at my options.

Best would be the 'S' setup with new calipers, disks, flanges etc at nearly £300.

At the moment I'm running metro 4 pots on 8.4" vented disks. this is all very heavy and you can feel the wheel skip on bumpy corners due to the high unsprung weight.

So i was thinking about just changing the calipers to alloy ones.

Am I correct in thinking that the minispares alloy four pot calipers for 10" wheels and 7.5" discs will be a direct replacement as long as I machine my vented discs down?

Also, do they use the same metro style hoses?

yeah theylll bolt on if you machine your discs, but they will use std mini hoses rather than the metro setup

Thanks Joey

Thats with a 7.9 disks though turned down from 8.4"

I may have a fiesta conversion that i'd be willing to part with for the right price, would include calipers, carriers, pads, machined discs and specially made braided hoses (metric one end, imperial the other). PM if interested

Spacers were only on until i'd ground the lugs off (now done) and the hoses aren't fitted in the pic.

Knowing how you do things you might not like the Minispares or Mini speed calipers - just check them out before you buy is all i will say

I stand corrected. You should know

iv got minispares alloy calipers with 7.5" discs on my runaround mini. they stop me but i would want a bit more stopping power in the turbo i think!

im going for alloy KAD calipers with 7.9 vented discs for the turbo. i think they should be better than the minispares ones!
i hope they are anyway! lol

i dont get this, how does a one brand of caliper stop better than another?

the pistons are the same size, as is the pad area...

fair do's the disc will be 0.4" larger, but isnt that really just splitting hairs?

i knew someone was going to say this, is this really an issue?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

Id like to say yes but have nothing to back this up,

Am sure someone will.

Dont forget heat disapation and weight.

In theory the greater the surface area touching the pad, the more heat will be transfered out of it.

I think this is the arguement for 6pots anyway. Only plus side i can see.

Some use aluminium alloy pistons. That's the worst idea ever!!

Ive had to replace me ally ones as the "Unwearable" anodised surface had worn away.

i am using 4 pot minispares calipers with 7.5 vented (8.4 machined down) and they stop very well once warmed up.

however they are meant to fit under 10" wheels i am yet to find a wheel they fit in they all seem to hit the "bump" on the inside of the rim, when i remove the outer bleed nipple most wheels fit but they all hit the bleed nipple, the minisport calipers have the bleed nipple in a different spot and i dont believe they hit the inner "bump" of the wheel.

i am yet to try minitor wheels, but i have tried mambas, and a few other rims only available in Aus and none fit.

and i cant afford Fastcarls wheels as much as i love them or MB's so its 13's for me.

The question was asked how one set of 4 pots can differ from another brand and my non specific answer was' monkey metal/flex' I am glad to see that I am not the only one to share this belief however it was not aimed at any one manufacturer or the other. I will however share this PM with you that I received

'scruffy

one of our customers has contacted us as he is a little concerend about comments you have made about our alloy calipers on this forum - he has just bought a set for a race car from us.

please can you quantify your claim that our calipers are made from 'monkey metal' and 'flex'. Neither of these are issues that we have ever come across in the 15 or so years that we have been making and selling this item, either as a investment cast unit, or as the newer cnc machined billet.

my boss, Neil Booth is more than a little miffed by your comments, as he is responsable for the manufacture of these items, which are made at a local iso registered areospace part manufacturer. they are tested rigorously and definately not made of any sort of 'monkey metal'. i have never seen, or heard of a set of our calipers suffering from flexing

we look forwards to your reply, with a technical analysis of why you believe the material choosen for the manufacture of our alloy calipers is, in your eyes, a 'monkey metal, and evidence of firsthand examples of our calipers 'flexing' in useage.

many thanks

At no time did I point any fingers directly - just said that Axel should look at the calipers before he bought them as they may or may not be up to his requirements. At the end of the day this is a forum and people should be able to express an opinion.

I'm dissapointed that Minispares choose to have a go at Scruffy, but can't be arsed to answer my original question.

Also the issue of fitment over 10" wheels is unanswered.

agree there, he said what differentiaties one from another and you said the material.

that seems fine to me and wasnt pointing any one in particular.

ive used 2 different sets of the ms cast 4 pots, solid 8.4" and vented 7.5"

i love them, never had any issues at all

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

gosh that ms letter came across as a bit sieg hiel ? they used the word ,
"miffed " isnt that actionable !!!

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

my query is i want to have 7.5" alloy 4pot setup to go under my slotmags. the thing is i dont know if they fit and which is the best brand to go for. because looking at the dimentions and sizes ect of the diffrent brands they seem all to be pritty much identical. i know the KAD calipers are about £200 more than the minispares or minisport calipers is the extra 200 really worth it?
