247 brake set up

[katiescar]

just wondered if anyone has used the 247 with 1155 pads on track, and just wondered how they perform, compared to say the 266 or 283 with std pads.

The old Cammed VTS manic motors demo car had this setup. Not sure which pads though, maybe 1144 or 1155's

they will stop you just as well to start with, but their heat soak capacity is obviously less as pad area and disks are smaller. A brake duct may help keep temperatures where you want them. If the suspension and chassis are uprated then theres less weight transfer, and the brakes are not worked as hard.
I'd say standard oe pads will be disappointing on track as you will have less pedal feel due to compression of the pads under braking and the low friction level of the pad compound.

Chris' (manic motors) old vts track car used 1144's on his 247 setup and said they were perfectly fine on the track ;)

i have used 266mm brake on track with standard compound. and 247mm brakes with m1144 compound. Both were disapointing. the 266 setup overheated (predicably) and the 247mm set up although no apparent brake fade was felt, the pads melted themselves.

I spoke to mintex technical guys explaining my set up and the recomeneded that i use 1166 pads. there opinion was that 1144 compound is only a fast road pad and not for use on track at all.

hope this helps.

Those M1155 and M1166 pads are really for high performance cars. I don't see how you could melt the m1144 in a saxo lol..
They are also made to order if your planning on buying some.

It doesn't matter what car it is at all.

I'd suggest that the 266mm setup with M1166 would be ok for a medium pace track day driver.

As has been said, different brakes CANNOT alter the stopping distance, but they can alter the number of heavy stops you can make on a track before over heating.

...thus altering the stopping distance.

they are not for high performance cars as a rule. they are for cars that put a greater amount of energy into the brakes. so high weight cars fall into this catagory.

I dont have any pictures, but i think i still have the melted m1144 pads somewhere to show you.

I have now gone onto use ebc yellow 'r' pads due to csot. Again these are dissapointing. So now im left with no option but to buy very expensive pads.

Oh brilliant - very clever!

Saying that big brake conversions reduce your stopping distance because "they don't overheat so quickly" is to poison and ruin the fundamental laws of braking and confuse n00bies who will be reading this thread.

Big brakes DO NOT shorten the distance your car stops in. That is down to the tyre grip against the road.

Big brake kits DO cope with heat better, so long after your standard brakes are faded and useless, will *STILL* be stopping your car in *THE SAME DISTANCE* that the stock brakes did when they are within operating temp.

Kind regards

I used to run standard calipers, disks and pads on my 205 rallye trackday car :D They are smaller calipers than the vts!
Standard pads were a bit crap but they were cheap as chips. Eventually we ran uprated pads and it was all good.
With regards to the mintex 1144's. They are really a fast road pad. They will work on track but they do not have a massively high temperature range so if you are experiencing high temperatures they will not survive.

yr51ocw - sometimes you have to buy expensive parts to save money in the long run....

something i'm having to come to terms with, as my front brakes are getting a little update at considerable cost, but as you say, it should pay for itself over the next few years.
