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 would love APs too, especially since I have had experience of both floating bobbins and AP's strap drive on my previous car. Floating bobbins can seize and wear out which can give both lateral and radial runout, the amount of salt and grime our roads tend to have just doesn't bode well for floating systems that use bobbins, thus my reluctance for Brembos. AP's still the most ideal system for us, but I just don't want spacers. If you do go for the 368mm kit, would love to see whether there's any clearance at all with our 219Ms. Go for it

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.
