pad suggestion for stoptech's

gtenedio · 04-10-2021, 12:50 PM

hey yall
looking for some feedback on pads, and sites to order.

stoptech trophy st60s/ st40's

looking for a combo street/track pad.

my front rotors need replacing too due to high heat- suggestions on site to order replacement rotors?

TY

Dtc70 and if you can deal with the rarest of squeals, you'll never have to swap them back and forth.

Zeckhausen, buybrakes, bestbrakes. All good.

With StopTechs, a pad change takes 5 min per wheel. Why not just get a proper street and a proper track pad.

I drive on my track pads to the track. Cobalt Friction XR2. They aren't that noisy actually.

derbo · 04-10-2021, 06:57 PM

I run dtc60 without much issues as my track pads. My wheels are always off during a tech inspection and post inspection anyways so I swap street pads

aus · 04-11-2021, 01:32 PM

Stoptech R34 is VERY popular here. R33 is also good with a little less bite.

Stoptech Sr33 front, Sr32 rear if you're on street tires. Slicks and you can go to something more aggressive like the Sr34.
Raybestos ST43 and 45 is epic too. I actually have some from my old ST60 kit and they have only two events on them. DM me if you're interested and I'll ship them out to you.

What tire(s) are you running? Stickier rubber works the brakes harder.

Kelse92 · 04-12-2021, 09:00 AM

I swap pads back and forth. I run Stoptech Street up front on my ST-60 and then switch to Cobalt XR2's for track use and swap back at the end of the weekend. I have stock rear brakes so I just keep the XR3 rear Cobalts on the car all the time.
Hawk has a decent lineup of double duty street/track pads I have heard about but have not tried.

If you don't mind some low-speed squealing and dusting, the Hawk DTC-60 would be fine on all four corners. Once you move up to something like a Hoosier then the 70 might be necessary up front.

I still think swapping to street pads is the best choice, depending on how much driving you do on public roads versus the track. I don't know what kind of pace you have on track, but a Ferodo DS2500 hybrid pad might do the job.

leftfootbr8king · 04-12-2021, 12:45 PM

Basically: if you're giving more point by's than receiving, the ds2500 will be fine. It won't fall off or disintegrate. However If you are the guy who is usually waiting for point by in your run group, you'll want something that lasts longer, otherwise you'll just be replacing the 2500's more often.

I don't drive mine to the track, but I do run these on the GTS3 car. I run XR1 front and XR2 rear (StopTech ST40 on all 4 corners). Quiet and easy on the rotors with strong initial bite and easy modulation.

redpriest and I have a list of acceptable pads.

1) PFC
2) PFC
3) PFC

PFC doesn't make pads that fit the ST60. Plenty of vendors say they're a compatible shape but as the pad wears, the pad backing plate will make contact with the rotor hat.

CarboTech and Cobalt Friction seem like the same company. I have CarboTech pads for my ST60 and like them.

G-LOC split off from Carbotech. Cobalt isn't related to them.

I know the owner of Cobalt Friction personally and he doesn't own any other brake pad companies.

Cobalt friction is where it's at. Talk to Andie if you need an "all conditions" pad.

Second this. When the Boss 302 first came out in 2012, he worked with me to come up with a compound that worked well for track days. Think we tried 3 and settled on the second one. Great to work with, quality product.

That's unfortunate. What about Endless?

To be fair, I haven't used the latest Cobalt (or any other company's) pad compounds so they may be great. I didn't like the Cobalts I tried years ago, but YBMV.

M eyedoc · 04-18-2021, 11:06 AM

I have been using Carbotech for the same trophy setup. Very much rotor friendly with plenty of stopping power. Currently run PFC when tracking my e46, but e90 likes the Carbotech best.

You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
