Essex endurance brake kit.

[diss7]

So I'm pretty close biting the bullet and getting the essex endurance kit for my track car.

Just wished there were more reviews and feedback on here. Lots of info about the sprint kit, not so much on the endurance kit.

Any info I'm missing..? Feel free to PM me if you'd rather.

Wheel size (aren't you running 16s?)and the ducts/ducting (with pipe routing for FI) apparently could be an issue but I forgot as I gave up on the endurance kit.
@CSG Mike would probably know.

I've got lots of wheels. They fit my te37's and se37's. Am selling my 16's as the street car is now turbo, and the new track car needs big brakes.

The reason you don't see more feedback on the Endurance Kit is that there just aren't as many Endurance Kits on cars. Most people choose the Sprint Kit because it's lighter, has less expensive spare discs, and the initial cost of entry is lower. For many people, the Endurance Kit would just be overkill. We've had the Sprint Kit on track FT86's up to 350whp without any problems, so it is extremely stout.

As mentioned above, the only "downsides" to the Endurance Kit vs. the Sprint Kit are as follows (keep in mind these are only "downsides" if you don't need the added thermal mass and cooling of the Endurance Kit!):

• Endurance Kit weighs 5 lbs. more per side
• Replacement iron discs cost $249 vs. the $165 discs in the Sprint Kit
• More expensive initial purchase price of $2599 vs. $2099.

As for wheel fitment, the Endurance Kit actually fits better on some 17" wheels than the Sprint Kit. Since the Endurance disc is slightly larger in diameter, it sits further away from the hub. Most wheels curve inward as they approach the hub, so the caliper tends to actually have more wheel face clearance when it's moved out a bit. On 16" wheels, then you'd have to consider the clearance of the caliper on the barrel of the wheel, and the Sprint Kit may be the superior fit. But if you're only going to run 17's or larger, you'll likely have more clearance with the Endurance Kit.

Your performance expectation when purchasing the Endurance Kit should be the same as if you were buying the Sprint Kit. The calipers in both kits are essentially identical, and the disc hat and brake line designs are also basically the same. All of the positive reviews and feedback we get on the Sprint Kits still hold true, you're just getting a few added features as a bonus:

• Larger, fully floating 325x32mm discs (instead of fixed 299x32mm discs)- Provides additional thermal mass for high HP or lengthy track sessions. We run the Endurance discs on tons of other cars with 500-600hp without any problems on track (Corvettes, M3's, Evo's, Late Model circle track racers, etc.).
• Integrated brake cooling duct attachment- Makes it easier to connect brake duct hoses, and ensures that cooling air is funneled precisely where it needs to go.

That pretty much sums up the differences. The Endurance Kit is sort of the "end all, be all" choice, and that's why we created it. I can't imagine anyone ever having problems with that setup, even if they push stupid HP numbers or run it all day and night on the track.

Most of our FT86 customers have sub-350 whp, and most only run track sessions in the 20-30 minute range. For those individuals, the Sprint Kit is the correct solution that we push them towards, and that's why you see more feedback on it. If you plan to exceed those HP numbers or run true endurance racing, then the Endurance Kit will be the proper fit.

I think as the FT86 platform matures, we'll see more feedback on the Endurance Kit. Now that the platform is a couple of years old people are really starting to push the power levels up, developing the chassis further, doing more engine swaps, etc. As that occurs brake demands & requirements will also increase stepwise.

Hopefully that all makes sense. Either of our Competition Kits will get the job done, it just depends on where your needs lie now, or where they will lie in the future as you develop your car.

That's a strong argument for the Endurance kit right there.

We'll be putting an Endurance kit through it's paces later this year

Right now, we're busy finishing up some other projects, but I have absolute confidence that the Endurance kit will work great.

Are you guys doing the NASA 25 hours of Thunderhill by chance?

Negative... although I regret turning down a certain seat a few years ago >.<

What about endurance racing, well semi-endurance, they're one hour sessions; NA power (because class racing) Car + driver weight + full tank = ~1200kg, and on 24/61-17 full slicks?

My worry with the sprint kit is that I will find its limit and wish I had gotten the endurance kit. The endurance kit has greater thermal capacity, and even then, has a provision for ducting. But it pays a weight penalty for that. Weight is something I'm equally focussed on.

I feel like if there was a sprint kit, with the same provision for the brake ducting as the endurance kit, that would be the kit for me.

ditto on this one.

[diss7]

Does anyone know the piston sizes of the sprint and endurance kits? I've looked everywhere, and can't find that info.

There is some info on the standard pistons sizes (38.1mm and 41.2mm in the sprint caliper) but are these the sizes used in the gt86 application?

Cheers

I think you've answered your own question right there... even if the sprint kit is marginally ok for 1 hour sessions, it'll probably be on the ragged edge. If it were me, I would get the endurance kit if I needed perfect brakes for a full hour.

You'll probably be cheaper in the end even with increased costs for rotors since you'll probably be going through less of them than you would be with the sprint kit running so close to it's limit.

CSG Mike I was looking at getting the endurance kit I saw that you stated 17x9 35 RPF1's would fit with 3mm spacers in another thread. Have you seen it done, and how was the fitment in regard to fender clearance? I asked the question in another thread and got no response. Im between the rpf1's and the mach V 17x9 any input would be greatly appreciated.
