HI Spec 4 Pot Conversion 285mm

[SteveC047]

I am seriously thinking about putting a 4 pot conversion on to the Trophy.

One of the guys I work with used to work for Hi Spec and can get a blinding deal on the 4 Pot Billet4 with 285mm discs, and a set of EBC Yellow/Red stuff pads.

I have been offered a set of Brembo 4 pots, but the price is nearly double that of the Hispec.

Pad wise i have used EBC before, and to be honest i had no problems with them at all.

Just wondering what you guys think of the Hispec gear.

If i go for the Hispec, they are going to get them Powered coated in red, and if i am willing to wait they will leave the logo off the kit so I can fit the renault sport logo.

Any information would be great.

Cheers

Well Brembo are better, but you won't notice much of a difference unless you are on track all the time, or racing of course.

The Hi Specs are cast so they are weaker than the better brands.

 

[Gweebs]

If they are better than standard 2 pot's, go for it. You can always sell them on if your not happy (there's always somebody out there willing to buy something).

 

[Fred@BTM]

don't powdercoat, get them to anodise them red

i've got the kit on my car, its pretty good, but as with all 4 pots the dust seals need replacing every so often depending on usage, and they don't like heat, but they're cheap to sort

if i were you i'd get the brackets knocked up so they fit your 280mm discs

 

[SteveC047]

The Hispec are actually Billet and not cast. That was partly the reason that i was looking at them and the Brembo, as they are made from the same material, to the same standards, it is just the internals that differ slightly.

 

[SteveC047]

Fred whats the reason for sticking with the 280mm discs, looking at the prices for replacement the 285mm work out about £15 cheaper. Just thinking that in the long run, what with replacing seals, pads and discs, it will start to add up.

 

[Fred@BTM]

eh?

285mm replacement discs from hispec are about £150

 

[Fred@BTM]

replacement pads are identical to Volvo 240 pads, £6.13 i pay for them!

 

[7MAT]

Steve, how many sets can you get and how good is the price?

PM me if you prefer.

 

[SteveC047]

ah ok then I will have a proper think about this.

In terms of the bracket, what needs to be done so as to fit the calipers onto the standard discs, as apposed to the 285mm.

Thanks again Fred your knowledge is amazing.

 

[Fred@BTM]

call me tongiht mate, i've already got the bracket design sorted, pretty simple

 

[SteveC047]

Cheers Matey will do

i had the the 325mm high spec 4 pot set up on a valver, and i all honesty, it was complete shite. would never use them ever again. they were in my view, worse than standard valver brakes. they came with ebc green stuff pads, so i dont know if that was the problem. but at the time they were the only pads available. go brembo, dont go hi spec.

Thats intresting, i have spoken to a couple of guys who has the first sets fitted and they said the same. I know that the pad which they use is a Volvo Pad, and they are available in Green/Red/Yellow and i belive Blue stuff from EBC, plus i can get hold a Tarrox, Mintex and a few other brands as well.

Its good to get a couple of different views from people. As all i get when dealing with these sort of companies through work is the fact that there product is the best ever, which tbh and from personal expereice is a load of rubbish.

 

[Fred@BTM]

you'll destroy the dust seals if driven hard (i have!)

 

[SteveC047]

Well thats one thing to take into account, the fact that i only have one driving manner and that is foot to the floor, means that it could become a bit of an expensive habit.

How long until your seals went, and in terms of replacing, by the looks of it, it seems like quite a simple job. I have one of the Hispec Calipers on my desk, just destroying it at the moment LOL

 

[Fred@BTM]

you know what i'm like with track days etc etc!!! they lasted about 12months, but thats only stopping a 1.2 16V

 

[fmp_]

if you want a very good 4 pot kit, at a decent price, i suggest you wait a few weeks for our 4 pot set-up.

Its being exclusivly made for us by compbrake (www.compbrake.co.uk). It will run a 295mm disc, that can fit behind a 15 inch wheel (depending on alloy design), 2 peice disc, aircraft grade alloy callipers, which are precision made, so dont need the use of poor dust seals that need replacing!

if you want more info, send us a PM!

 

[SteveC047]

FMP thanks for that i am defiantly intrested in that. PM Sent

 

[fmp_]

cheers for the PM's, literally heard this morning that all design drawings had been finished, so getting full details tomorrow, so can post up all specs and info for people!

cheers.

The Hi-Spec Monster 4's on my Hybrid are amazing, I am however using Ferodo DS3000 pads which once warmed up can stop me on a 10p piece. The only downside is the dust and the squeeling from the pads when cold.

I have heard alot of people say that the Ferodo pads are excellant when warm, but an absoulte cow when cold. I believe that Hispec recommend for every day use going for the Red stuff compound mainly due to the fact that from cold they work fine, with limited squeeling.

Once again thanks for the information, i am very tempted, with this sort of set up, just got to see what my options are, and get saving the pennies.

 

[Joe@ShedMotorsport]

As mat said, we should hopefully have all the details later on today.

I used to use DS2500's on my old Lupo GTI and they never squealed at all (i think mine came with an anti-squeal backing). They don't bit instantly but it literally takes a split second for them to get upto temperature, they are awesome when they up to temperature though.

 

[Anonymous]

They only squeel because the DS3000 are a dedicated track pad, the DS2500 & DS2000's dont squeel when cold or very minimal

 

[drsmith]

we got any suggestive prices on these new kits @Shed

 

[Joe@ShedMotorsport]

I can't give out any prices right now as i need all the details through from compbrake so i know what exactly will be included in the price of the kit i.e pads (I expect these to be extra so you can choose your own compound), hoses etc. We're hopefully going to be doing an introductory offer on them as part of a group buy. We'll keep you guys posted.

 

[drsmith]

in the words of a very wrinky old geezzer from the simpsons.......

Exxxxccelllent! :evil:

Sorry to pester you about the kit, but you dont happen to know what grade alloy they use on the kit.

Just that i have been looking into this a bit further, an noticed that there is a huge difference, between the grade of allloy that Hispec and Brembo, to what Wilwood use. I also have read that the Wilwood calipers, are prone to flexing, under mild to heavy use, and in some instinaces can warp the caliper when extremly hot. I know this may not happen on something as small and light as the Clio, but having that thought at the back of you head, when you are doing 110mph on the straight at Donnington and having to brake down to 30/40 for the chicane, wouldnt leave me with a huge amount of confidnece.

I really aprrciate all the help you guys have given.

Willwood are cheap for a reason mate.

Brakes/suspension & tyres are something I will never scrimp on

 

[MarkM]

not sure which calipers they are using in the kit but info is here

http://www.compbrake.co.uk/Calipers.htm

The top of the range one uses 7075 but the others just say aircraft grade aluminium

 

[midge]

the wilwood pads in my wilwood brakes squeel like mad when warmed up ?

 

[SteveC047]

Willwood are cheap for a reason mate.

Thats partly the reason i want to find out which is the best made kit out there. from looking at the specs between Hispec and Brembo, they use a similar grade of Aluminium, and both are CNC machined as apposed to cast like a couple of other kits i have seen.

 

[SteveC047]

Had an intresting conversation on Sat with BB Tuning.

They said that the Billett 4 kit from Hi-Spec actually uses a smaller pad than the standard brake set up, and adviced me to go for something like the Monster 4.

Only thing is i dont know if the Monster 4 will fit behind the wheel now:S

(Awaits Freds reply)

 

[Fred@BTM]

correct, the billet 4 does use a tiny wee pad (off a volvo 240!)

why do you need to upgrade steve anyway? the stock calipers and discs are bang on anyway!

and as far "warping" calipers - unlikley!

They fit behind 15" williams wheels with 300mm discs mate as mine are the Monster 4's

If your local to Cambridge your more then welcome to pop round and try them out on yours.

 

[SteveC047]

Fred

The reason why i am looking to upgrade is the fact that i am getting really bad brake fade, pretty much all the time.

First step is to get the braided lines, but i will need a new set of discs in the next few months, as the ones on the car know after 14k have quite a noticable lip on them.

 

[midge]

braided lines.

thats easy to solve! buy one of our brake kits LOL!!

 

[edde]

I used to have a set of Willwoods and I'd buy another set with no hesitiation there fine. If your using it for a lot of miles then dust sealed are the way to go even if there more expensive. I never had any trouble (beyond what I caused) to them in the time I had them stunning brakes.

 

[Fred@BTM]

the size of the pads isn't actually much of an issue in all honesty
