Been tracking my car a few times now, and want to get steels for increasing my track days.

Is it necessary to switch out the entire caliper, or can you switch out the pads, sensors and discs, and keep the calipers.

Thanks

Calipers don't need to be changed unless you're going to a full Stoptech or other 3rd party manufacturer kit. Plenty of food aftermarket options for rotors and pads - PFC, Brembo, AP, Girodisc...

Depending on your pace and frequency of use they will turn orange, or purple for red ones. Easy enough to refinish though

...just curious...when they do change colour, and eventually need a service, do you suggest rebuild or just buy new new callipers?

I've gone from PCCB to Girodisc and kept the yellow calipers. I'm very happy with the switch. You won't regret it. I use Pagid Black pads on the track and OEM turbo pads on the street.

Being able to go to a more aggressive pad for the track is great. There are other good choices for pads.

The turbo pads on the street are silent on the iron rotors.

Heat makes them change color. All calipers eventually need service. Rebuild or new depends. Rebuild is cheaper especially if you do the work. But if bores are scored or other issues just get new calipers. They aren't inexpensive

I haven't tracked my GT3 much (4 times only) however my turbo i had dozens of tracks days. I'm no slow turtle however my yellow calipers never turned orange like others around me did. I was equally as fast or faster...i would put this on driver dependent.

Probably more brake pad dependent. some pads put more heat into the calipers.

This.

Very valid point.

PFC, Ferodo and Pagids for your car - and I'd watch the REARS - they seem to give a few problems.

Fronts have their own small subset of an issue: pad tapering. Think of a doorstop. Flipping the pads is the key here -

I've added GT2 air ducts for the rear brakes to keep them cooler. Good idea if you plan to leave TC control on. The rears do a lot of work then. The pads will wear fast and the dust boots around the caliper pistons will crack from the heat.

Someone. at some point is going to solve this by working their butt off rigging and installing a set of small high velocity SPAL fans to force air on the rear calipers -
