2G Powerstop Calipers?

[Mmmmrspicy]

Hello,

Need to overhaul the brakes on the eclipse. Has anyone bought these powerstop calipers off of RockAuto and has some feedback? I also saw these black drilled/slotted rotors as well, thought that might look nice if the performance is there. Here’s a pic of the shopping cart. Let me know!

I didn’t buy the powerstop ones but I bought the raybestos r line ones for $55 and they came looking immaculate and brand new. I painted them myself for $9.

I got the red powdercoated ones about a year ago now.
They work great, seals all looked good and they are great looking units.
To my knowledge, I had to re-use some stuff off of my old brakes but I dont remember.

I just ordered the power stop cross drilled/slotted rotors last week, they show up tomorrow , they’re way cheaper thru rock auto than say stmtuned.

I have bought those exact powerstop callipers, front and rears, but only installed the fronts at the moment. The red is very nice and it is actually a powdercoat, there are some very small areas in corners that didn't get coated, but overall they look good. They fit just like the old oem ones.

 

[randman2011]

I've been running them on the Eclipse for a few years and other cars for probably a decade. They're rebuilt OE calipers that are powdercoated red. What else can I say? For any car that just needs red calipers, these are the ones to get.

How long does the black coating last on those R1 rotors? I know with some rotors the pads strip it off in the first 100 miles. Just wondering if the r1s last longer

 

[Mello]

Never had R1 rotors but I would think the pads would remove the efinish as the pads bed in. I also feel that I would want the coating to be removed from the friction surfaces for best braking too.

Yeah, you wouldn't want that coating to stay. Lol. I think the coating is more for all the non-braking surfaces to help fight rust.

Let me rephrase with what im really trying to find out. Was curious if there are rotors where the surface stays a dark grey or black after the coating rubs off.....but not trying to hijack the thread from the question asked.

 

[Mello]

The raw color of rotors is cast iron. You can get black rotors by getting ones made from carbon-carbon.

Thanks, all!

I'll probably get the R1 rotors next time around. I warped my Powerstop rotors within 2 months of installing them. Even the OEM rotors wouldn't have warped so easily. Not what I expected from drilled and slotted rotors.

For what it’s worth their rotors haven’t warped a single time on the edge. I warped the piss out of the stock(very well made) rotors and under identical “situations” these haven’t done it. And I’ve done that “situation” repeatedly. Lol. They’ve been amazing at slowing this heavy pig down. My only gripe is brake fade is a real thing when they’re really pushed. But it’s a 5000+lb CUV on absolutely stock sized brakes. Can’t really fault them. Still haven’t warped tho.

Did you bed them and follow their specific procedure they tell you to do? Because it warns you if you don’t, that the rotors will warp.

I would end up with pulsation every 10k miles with the original single piston front brakes. I don't say warped because it wasn't clear they were, but they didn't stop the car and vibrated badly. Since it was a new car the dealer tried cutting them, then replaced them, and then replace both the pads and the rotors before we both gave up.

Once I bolted on the dual piston calipers and the matching sized rotors I never had the problem again.

I've run PowerStop rotors, Centric, and whatever was cheap at the box stores and didn't notice any major difference in braking or life after the swap. The various coatings usually strip off the braking surface in the bedding process and the rest might last a year before the rust takes over everywhere else in the rust belt. In Texas it might last forever if you not by the Gulf.

 

[Mmmmrspicy]

Thankfully, I’m in Dallas, so rust shouldn’t be a major issue. It sounds like it might not be worth going with if it doesn’t provide any real benefit over stock…

I'm not sure how you came to the conclusion. I don't believe your Spyder GST has the dual piston calipers. There is another option when using them, that is what's called the Outlander upgrade. It allows even bigger rotors to be used.

 

[slugsgomoo]

single piston brakes have issues because there's just not enough thermal mass to dissipate the heat from any spirited driving on a car as heavy as ours.

For what it's worth, disc brakes work partially because the pad deposits material on the surface of the rotor which increases the coefficient of friction- Unless your rotors have literally glowed, the likelihood you're seeing warping, versus uneven pad deposits is effectively zero

IMO once you have two piston calipers, the three most important mods are stainless lines, good pads, and good fluid. If you have any old fluid left in the system, flush it out.

Oh, and if you have a 1g/vr4 especially, delete the absolute trash that is the 2 channel ABS, as it adds barely any advantage in smashing the brakes when you shouldn't (like mid-corner), but dramatically increases stopping distances in the dry.

Curious if the Outlander upgrade will work with the stock chrome wheels?

The Outlander upgrade uses just Outlander brackets to move the stock 2 piston caliper outward more, plus the larger Outlander rotors. It wouldn't have any risk of lack of forward clearance and I THINK there's still plenty of diameter left inside the 16s, but let me check mine. I have the 17" GSX wheels but I can tell you how much clearance I've got on mine and subtract a half inch.


I can't get the tape measure up in there AND take a picture but I have nearly exactly an inch of clearance at the closest point between my GSX 17" wheels and the Outlander brake upgrade. 16s should have no problem at all and there might even be a chance of fitting 15s over this, but I wouldn't risk it.

Excuse the dirt. This is my winter car.

These are the aforementioned Power Stop calipers, by the way. I had the Outlander brackets powdercoated to match. Centric slotted rotors.

Awesome, thanks!

 

[CrackedDSM]

My stock rotors were definitely warped and not just pad material.

Could definitely have also been “literally glowing red” though considering conditions.


Super impressed because under the same exact conditions that made the OEM ones scream for mercy the PowerStop stuff just shrugged off. Love these things.

This message below is what made me think that.

I’m looking at different dual piston front upgrades and was looking into GSX parts which was why they were in the cart. It looked like some folks had done something similar? Maybe I’m crazy though?

This seems awesome, thanks for the detail!! I’ll go back to look into this more this weekend.

It was maybe.....2016 when I purchased the powerstop powdercoated dual piston caliper kit.
Their customer service was really nice, but I had to work with them a lot longer than I should have because their supplied caliper brackets were completely wrong, they were either intended for the single piston units or from another car entirely. They sent out multiple sets of brand new brackets that did not fit.
I finally got their team to correct the issue and it sounds like all of their units for sale since have been sold with the correct brackets.
The actual performance of the brakes were perfectly fine. I don't know what kind of "upgrade" you're expecting.....it's a stock replacement unit...it'll do better than calipers with 140k on them
