FreakyParts 4 pot brake conversions


is there any updates on the 4 pot kit? anyone tried under a OEM ek9 wheel?
 
At the moment OEM wheels will not fit under the "ultimate setup" but it is close and is still being worked on.

Ok then, I hope you're sitting comfortably.

EK9 standard:
Pad spec - 148.7x57.7x18mm
Total pad area - 8579.99mm^2
Disk diameter - 282mm
Total sweep area per rotation - 40658.8377mm^2

Wilwood Superlite and 298.5mm disk:
Pad spec - 120.4x61.7x20.3mm
Total pad area - 7428.68mm^2
Disk diameter - 298.5mm
Total sweep area per rotation - 45513.82357mm^2

Difference - 4854.985871mm^2

So for each rotation of the disk when the brakes are being used, you're covering nearly 5000mm^2 more than the standard single piston caliper with the Wilwood Superlites and the larger diameter disks. With the pad being slightly smaller in area, it will wear quicker as it's travelling further per rotation, but to compensate that, the pads are 2mm thicker each side, so you're getting an extra 4mm of pad material.

Also something to bear in mind is the piston area you've got applying pressure to that pad.
Assuming the single piston is the same diameter as the DC2 (57.2mm) you have a total piston area of 2569.6971mm^2. With the Superlite caliper using 4x 44.5mm pistons, you have a total piston area of 3110.5694mm^2, a difference of 540.8723mm^2.

Pad size isn't the be all and end all of brakes. You really need a complete package to complement the pads. If you can apply more force to the pads, more evenly and have the pads travel further per rotation, you're going to achieve better modulation meaning you have the ability to find the point just before the brakes lock up easier (which is the point you want to get to - a locked wheel will slow you down slower than one just before the limit). Also with the pads travelling further per rotation, and the disks being 32mm thick instead of 23mm the disks have more time to cool down before the pad comes into contact with that section of the disk so you're not going to cook your brakes.

can you get me a price for a set of these for 96 spec integra typeR
 
I would like to offer my car up as a trial car for fitment purposes, i'm located nr Sheffield, Derby and Notts Junc 29 M1, dunno if this helps you Freaky Parts?
 
Quite possibly. I'm currently looking at the option of using s 20.6mm thick disk as an alternative to the 32mm one. the downside is it will be thinner so wont be able to cope with the high temperatures as well, but the upside is it should be able to be moved 10-12mm futher in to give better clearance.
 
interesting, So only oem EK9 wheels will have fitment problems?
So a 15'x8J will have no problems? Which kits are available for my set up.

Please pm me.

grt.
 
a 15x8" wheel should provide the clearance you need to fit the 298.5x32mm thick kit. I've got a template (if it's not already on the thread) which shows you what space you need to clear your wheel.
If you download this PDF and print it out, then whip your wheel off and test it, that'll tell you if it clears.

great, i will test it out.
 
Yes, they supply red and platinum coloured ones. The red ones are stupidly expensive as they're powder coated from the manufacturer, the platinum ones are the same price. I'll be trying a set of those when I next order some calipers, see what they're like and post some pictures.
Alternatively, I've spoken to the suppliers before on painting them and they have no problem with you doing it yourself so long as none of the moving parts (pistons, nipples, crossover pipes etc) are painted.
Otherwise, I can ask the bodyshop next door to the engineers to paint them, I think he charged me £50-£60 last time I had a pair painted by him.
 
I'm looking at doing a kit which uses thinner disks, a 298.5x22mm 2 piece disk would be the same price but would give approximately 10mm more clearance to the caliper as it will in theory sit 10mm further back. It won't have the same heat disipation the 32mm thick disks do, but will be better than the OEM as they've got a larger diameter.
The kit will be around the sane price as the parts are no cheaper.
 
Might be interested in the 4-pot Calipers and brackets for my front brake setup.
I have a 98 Civic Coupe with 282mm NITRAC grooved discs (MG 4x100).
Can you pm me a price for a set shipped to the Netherlands?

Would like to keep the 282mm setup since i'm running on 15inch during trackdays...

Thanks!
 
My Freaky BIG brake kit let me out brake a 2007 Porsche GT3 on Silverstone the other day. Yes he definitely was trying.
