I've got a 2020 GT without performance pack (i.e. 4 piston calipers). Currently I'm using G-LOC R10 & R8 pads and I don't like them. However, I'm having trouble finding any other options for track pads from any vendor for the non-PP car. I've looked all over for Performance Friction (my favorite) and Hawk (very popular) and they don't seem to make any. I know I can (or at least, I used to) get custom pads from PF, but I'm sure a stock item would be less expensive.

At this point, I'm only concerned with the front brakes. Any suggestions?

Thanks,
Michael

Unfortunately this is one of the bigger reasons to go to the 6 pistons: pad selection. Didn't you just get some?

I wouldn't use the Powerstop Track Day...they have copious amounts of corrosive dust and eat rotors like they're top-shelf pizza when driven on the street. Hawk doesn't really have anything track worthy except the DTC series (the HP+ and Street/Race are marginal).

^^^ Hawk's HP+ have a similar appetite for iron, particularly in street driving at cool-ish temperatures. Been there.

Thanks Brian. Right after I posted (but after you saw it) I found that Steeda does carry the Hawk DT-60 & DTC-70 in GT non-PP sizes. So that's what I'll go with (60s).

You have a good memory, but what I bought were the Steeda 2-piece rotors to fit the GT setup. I have those and the G-LOC, and I don't care for any of it. So I'm going to try a less aggressive pad, the OE steel rotors, a lot of venting for air flow and slower speeds. Old man track driving. I'll get one of those stickers...

I'm seriously curious about what you didn't like about the G-loc pads.

And what you didn't like about the 2 piece rotors.

I honestly don't know where the blame lies, in the pads or the rotors. Like most track pads, they are noisy. Is it the pad, or the slotted rotors? I suspect a bit of each, so I'm going to try something else. For most people I'm sure it's a minor thing, but I'm a bit particular and a lot OCD.

Yes, G-LOC R series brakes are noisy, just like any track-focused pad.

The noise is from the pads, not the rotors. That being said, the noise is unavoidable. Any serious track pad, regardless of brand, is going to be noisy when cold.

The OEM PP pads don't make much noise at all and can stand up to mild track speeds. I believe those are Ferodo brand. You could call them and ask if they have anything in non-PP size or if they could make you a custom set.

Track pads are going to be at their worst for noise when you're using them the 'gentlest'. And once the noise shows up, the usual driver reaction is to ease off the brakes. Wrong answer. It's somewhat contraindicative, but what you need to do is brake harder. Following traffic conditions permitting, of course. It can also help to work some harder-than necessary braking into your normal driving, subject to the same caveat.

I've run OE rotors (plain), Centric plain rotors, DBA grooved rotors, and ATE grooved rotors, all with track pads. They all made some noise, but was still dependent on how I was using the brakes. IIRC, Hawk's HP+ weenie-track pads were actually noisier than Carbotech's moderately serious XP12.
