D2 Racing 6 Piston Front Brake Kit

Hey guys,

as some of you know, I really like tracking my Fit even though most of the time the car is used as a daily drive. Last time on track, I kinda ruined my brakes. I checked them with a mechanic and there are blue traces on the discs in front, the car also turns a bit to the right when breaking hard now.
He said that it seems as if the brakes are already damaged and I should not use them on track in future. I use OEM brake pads and the original 210 mm x 21mm discs.

Unfortunately, there are only better brake pads available, I did not find any slotted rotors in Europe that fit without problems. Another question would be if these parts were street legal here.

However, I've just stumbled across the D2 Racing 6 Piston front brake Kit that is made for the car and also allowed here. What do you guys think of it? I know the company name but do they produce high quality products? D2 Racing recommends putting better brakes all around the car but this is really expensive. Can I also use the brake kit in front and maybe better brake pads in the rear? Most of the brake balance is in front so there should not be a problem with overheating, nearly OEM brakes in the back, right?

Here's a link from their website:
Bremsanlagen 286mm

Thanks for any advice. This seems quite important, even for a car with such small engine. I can't believe the brakes only last 40 km (2 laps Nordschleife) pushing hard.

Firstly you should try adding better pads, stainless lines, and especially fluid to your oem brake setup. Stock pads and fluid are designed to withstand day to day driving, but are the worst thing for hot lapping your car. You would be amazed at how much of a difference a pad compound change, and fluid with a higher boiling point are. Try doing dome diy brake ducting for your front rotors.

D2 racing makes some ok stuff. Not top quality, and not rubbish. Just kinda in the middle.

As for changing the fronts only and not the rear. Good for show points, bad for performance. Your brake stopping distances will become worse because you will be having so much front bias that the rears will not be allowed to work as effecient. Even with a performance pad change in the rear it wont be ideal. Either dofront and rear at the same time or not at all.

Lasty, you didnt address them but Im going to point it out anyway. Tein S-tech springs are some of the worst springs for tracking as they are progressive springs that change their spring rate aggressively upon compression and rebound. They are more a show spring than anything. Definetly not your best drop-in for track racing.

6 pistons and your car will do endo's probably.

I asked EBC Brakes via e-mail and they told me that Greenstuff pads can be used with our OEM brake rotors. However, I should be cautious because the rotors can still overheat. DIY brake ducting is not allowed in Germany. This may be a good idea but I don't want any problems with the police and insurance.

I've just received an offer for slotted rotors but only for the front. The size seems to be identical but maybe it helps?

Your explanation sounds very reasonable. Another idea would be to use the rear disc conversion setup. There are stainless lines, sport brake pads and 288 mm slotted rotors included. The only problem would be that I already got brake rotors in the rear and if I really swap to 6 pistons with 286 mm rotors in front, the rotors in the back will be 2mm bigger. Is that a problem?

When I got the springs I was more into style than racing. That changed with the first time on track. I did not know this, thanks for your information! I only felt that the whole suspension seems to be a bit too soft. I am looking for Tein super street coilovers in future but it depends on the budget.

Anyway, thanks for such useful posting. Thumbs up!

In general, d2 isnt the greatest quality.

Here are some very good options for big brakes on the Fit...check it out!

I've personally never run across any major problems with any of the D2 Coilovers or LCAs I've owed. I did blow out one of my shocks one a set a few years ago, but it was replaced by D2 no questions asked.

Be carefull with those ebc's. They tend to start on fire when they get too hot. Ive got a friend that lit up the red ones on his 240sx on a pretty mild track day.
