I'm sure there are benefits of getting a rear GT kit (quality rotors, radial mount, new parts etc) but isn't it possible to run the front GT 4 pot with STI/PP or EVO X swap on the rear axle since the pistons/discs sizes are the same ? |

If you care about car handling and braking efficiency, you should care about not shifting brake bias too much to make car unstable under heavy braking or have it's braking distance longer with those .. hmm, "brake upgrades". In most cases ability to bolt on mounting wise calipers from other car doesn't mean it has same brake torque OE one it replaces, obviously shifting brake bias. IIRC about the only safe retrofit bias wise was from WRX of some gen, and it was about front brakes, not rears. If one intends to track car, imho brakes certainly are not something to compromise to save some money. Advanced motorsport crowd may do it in educated fashion by properly testing by themselves on brake test rig or skidpad, in some cases also using staggered pad compounds, brake biasing valves and so on, or even willingly going for different bias (due eg. different aero downforce mods that change overall grip bias) but for average Joe wishing "5 trackdays a year" blind retrofit "just because it can be mounted and is cheaper" imho is path they shouldn't take.

There were a lot of people tracking their cars from 2013 to 2016, before the PP was a thing.
Many on OEM calipers, and also many on quality BBKs. The good kits consider brake bias and are excellent with the factory rear calipers as mentioned. We don't know when or what to expect from the PP. - Andrew |

GR86 upgrade stock brakes or wait for Performance Pack?
Does bias even matter with EBD?
Isn’t EBD the main reason the car doesn’t rotate under trail braking too? |

Also, doesn't pedal-dance, many track with, disable EBD in addition to e-diff, leaving only basic ABS?

In practice, this is not a big deal but should be pointed out... Q: Sorry if I missed this, but what pads are you planning to run? I would be very surprised if you couldn't find pads that'll work with the standard brake setup. [edit/addendum]Every driver uses brakes differently! Some drivers may find that they *do* need upgraded brakes for hard track usage... Last edited by ZDan; 09-28-2021 at 03:38 PM. |

To answer your question, with my previous track setup I thought I would be good to go to run GLOC R10 pads all around, which are definitely a true track pad, not dual duty. But I still dealt with brake fade. So this time around, the GR86 being a heavier car with smaller rotors and pad surface area, I should go with GLOC R16 or something. Still need to do research there. Or I could consider the CSG C2 that Mike suggested, if their price is competitive and reviews are up to par. Note: If you aren't familiar, GLOC is an offshoot from CarboTech. The owners, or something, of CarboTech split up, leading to GLOC. I've read a lot about GLOC actually improving CarboTech's formula, so I've been going with them.

Any aftermarket bolt-up kit is going to have an axially-bolted interface with the factory knuckle/upright . Only way to get a "radial" bolted joint there would be to have a custom aftermarket knuckle/upright. Quote:
CSG C2 were a big upgrade in terms of feel (great bite but not overly hyper-grabby, important for me because not running ABS) and temperature-consistency and longevity for me, though I never had fade issues with XP10 (on 550hp FD with StopTech ST40 brakes and 328mm front rotors). I also end up running the C2s on the street a fair amount and I find them perfectly streetable save for some noise... Worth a try IMO! If temp/fade is a primary concern of course check wit them for recommendation. BTW I shouldn't suggest that what works for me and what I like will necessarily work for you or be what you like. IMO brakes are very *very* driver-dependent. It's weird but different drivers even turning same lap times in same car can have *very* different wants/needs for brakes in terms of feel and ability to take heat. So ultimately even though I don't think *I* would require Brembos (though I definitely like having them!), that doesn't mean that you might not! So apologies for previous post giving that impression.
