Track Brakes

[sir_dave]

Right ho, slowly amassing a few parts now, but am having some slight doubts as to what to actually fit to the car. Its being built for track/spirited road driving only so i am looking to get some decent, fade free stopping power. Wont ever have more than 150bhp.

My real issue is whether to fit the gti6 setup that i have, or go for the 266mm instead - purely so that i can fit 14's, ie rallye steelies as tyres are cheaper ... discs/pads are also cheaper.

I currently have the following in various boxes in the garage

Standard gti6 front setup
Mintex 1144 rear pads & Grp N discs
Braided lines
Castrol Dot 4 fluid

Are the 283mm's worth the extra hassle over the 266mm's, ie grinding/expense? And what would be the best pads to go for, would the 1144's be ok on the front as well, or should i go for Ferodo DS2500/CL RC5+'s?

ok basically avoid the rallye steels if its going to be a fast track car, also go for the gti-6 with some grooved or drilled discs to keep the temps down.

with the steels your brakes will get very hot very quickly causing horrible brake fade. always runins a few hours on a track day.

i understand you want to try keeping costs down but you will kick yourself. the smaller discs will generate more heat and faster aswell being insulated by the steels.

best bet would be gti-6 on the mintex pads with some nice discs.
also run some cold air feeds to each caliper to try cool them if you decide to use steels and 266's

carbone lorraine rc5+ is far superior to the DS2500. Unless you are running big disks to keep things cool enough, the 1144 is not really suited as an all out track pad

m1144 are not track pads.

EBC yellow stuff R are very good pads and cheap.
I was un sure about getting them, but glad i got them.
Quite alot of people have started using them, and safe to use on the road.

Oh and they are cheaper than m1144.

i did a lot of looking into this a while back

from the info i gatherd (from respected members on here / other forums) it appeared clear that the 283mm set up wasnt worth the extra ££ over the 266mm, it also weighs a lot more and is still just a 1 pot caliper

if you dont mind spending more, you could get a set of 4pot brakes with discs & pads for £300 2nd hand, i bought some wilwood midlights for £350

EBC stuff is ok, nothing brilliant though. I supply a lot of pads to race teams who struggle with their products on track.

Hmmm ok, steelies are out the window then. Have bought some 15" Comp Mo's anyway, so the 14s would be more more driving to & from track really (or if i killed the tyres part way through a day!), 4 x vtr wheels & tyres are only £60 lol. But they wouldnt fit over 283mm's ...

Cooling mods are in progress as well, well i got the hacksaw out anyway ;)

So would a 283mm setup on the front running Carbon Lorraines be noticeably better than the 266mm running the same ... ? I suppose, being fairly novice at mechanics, im not overly keen on getting a grinder out lol

[Sparco_Tom]

steelies are good on the road :y: or even for short stints. i could do 15mins on steelies before i needed two cool down laps

[Ashleyp]

i still say a 4pot set up is the only solution

[Sparco_Tom]

ideally it would be

[sir_dave]

ideally it would be

Money in the garden is dying though :n: & this was supposed to be a cheap track car lol

a decent 266mm set up would be decent enough

if a 4pot set up isnt affordable that is

[Dan-Subtle]

some 6 pots would be even better :P

sell them for what you paid and im sure he would buy them ;)

£350 and their his then :P

With the carbone lorraine pads you will not have any pad overheating issues. I'd get new brake fluid in though at the same time though.
Pad area and distance from the fulcrum will not affect how quickly you will stop, but it will affect your brake pedal feel, and the larger the disk and pad the more heat the braking system can cope with.
