What kind of fixed calipers?
From my experience on my E46, there is a significant difference between the OE euro floating rotor and the Stoptech Aero Rotor. The ST rotor just lasts a lot longer. The OE floaters wore pretty well but I had to replace because of heat cracking after 2 sets of pads.

Sorry about the delay on this project. I had to move it the back burner since I moved across the country. TO answer your question though, the calipers are ready but we have to do some testing before they can be released.

This has been around for a while. Caliper uses wrx shape pads, which are small and comparable to our stock pads. I dont't know if they match the swept area by the stock pads, as I didn't research further. If they don't, effective radius will be bigger, which means brake torque forward is increased and so brake balance is affected. I think it is generally difficult to create a fixed piston caliper for the stock rotors because of pad choice.

So what exactly is lacking with the stock caliper?
I agree with Bigjae..might aswell do it right and go BBK..otherwise if staying OEM..pad upgraded is all thats really called for. |

-uses a common shaped pad -has a larger friction surface area than OEM -has taken brake torque, balance and heat into account I have a lot of practical reasons to not want a BBK that I shan't bore you with, but neither am I looking to upgrade the caliper just for cosmetic purposes. I'm happy with the performance of track pads with the OEM setup and don't need the additional thermal capacity of a BBK as I don't tend to do more than 10-15mins of hard driving each time I go out on track. But I do like the benefits of a properly engineered fixed caliper over a sliding one. |

I think a system utilizing the OEM rotor can work but I'm not sure what improvements you get. Most pads for fixed calipers are more expensive. Just some food for thought. ![]()

I just went to the track for the first time and I ran full track pads and race fluid. Granted I am a noob so I am hard on the brakes but this track (Big Willow) is easy on the brakes and I was still overheating the rotors. So I think that upgrading the rotors is a necessity performance wise. I do think that this could be a good cosmetic mod because our brakes are very ugly.

I've done about 26k miles and 5 track days (search mlhj83 on youtube) with my current OEM discs, and they are still going strong. |
