OK, so we know the OEM brakes on the M3 suck...(You know this if you don't drive like a pussy
There is no venting to the brakes, like on all the other performance cars.
And the fading kicks in after 2 laps of hard driving on track and sometimes even with some high speed action on the highway.
I liked the GT4 kit, with Carbon Inlets and custom Aluminium backplates. But it's !1300! EURO excluding ducting!!!
I have a trackday @ Spa-Francorchamps on the 8th next month.
Yes, i'll post cool vids of onboard laps.
I decided to fab my own brake cooling system.
You need these parts:
Alu brake ducts
Brake cooling ducts
You need these tools:
Cutting tools like, Knife, Circular grinder (Dremel)
Drill, same size as the rivets
Hex key 8 and 10
Some duct tape
(excuse my iphone picas)
1: Undo the front plastic inside wheel liners in the wheel arches. Hex screw Size 8 and 10.
2: Undo the front floor in one piece. Hex screws size 8 and 10.
That should look something like this.
This is how my finished product looks like BTW. And yes after I took this pic I cut the ducts to the same length.
If I remember correctly the length was 42Cm (17''). Measured from where the duct 'exits' the floor till the end.
3: Leave the pieces on the sides of the floor on.
4: I got these round Alu brake duct inlets.
I <3 my focusing to0...
I riveted them in to place. With 8 rivets.
Yes, thats heavy duty riveting. it's not going anywhere. And it looked cool (up close)...after i spray painted it flat black and installed it on the car it doesn't show...
5: To get the brake duct in to the wheel arch you need to cut some at the back of the floor.
It should look something like...
