I know that FD...soooo nice, and those brakes are perfect

AP is where its at when it comes to brakes!

woohoo!

on the front steps today. more info and an install write up on the blog and facebook coming soon...

I know performance wise, 99% of us will be well served by stock calipers/rotors with some good pads and good fluid but damn if that setup isn't sexy.

This is one of those cases where it looks sexy AND it's functional. That's not always the case in today's world....

ignore any braking performance increase, and the cool look. 20lbs of unsprung rate is a ton to shave off.

This.

Word. We're excited. :)

I want a review of the difference in not just braking power but also driving feel due to the weight reduction

Yesterday I received another review and pics from an S2000 customer who installed our Sprint System on his car. This gives a good idea of what it looks like behind black wheels of a different type (sweet Volk CE28N's), and on a dark colored car (this is actually called Moon Rock Metallic, and isn't a USDM color). Check out our blog for a couple more pics and the review.

"At the end of the day the pedal pressure was still as firm as when I first installed them. I find myself wanting/needing a proper harness to secure myself more tightly as I did feel like i was being thrown forward at some of the harder braking corners."

Thats the best quote from your customer Jeff.

I doubt you'll run into any install issues...super easy...but don't hesitate to call if you have any questions. Enjoy!

That is a very difficult one to put into words. My hunch is that a sensitive driver would be able to feel a difference if they installed the brakes and a lightweight wheel/tire package. I went with a 7 lb. Volk wheel on my Miata and instantly felt a difference, but at 2100 lbs that car is quite different from the FT86. When I have the passenger seat in and someone is riding with me on the track (+200 lbs or more), the handling is all jacked up and it feels like I lost a cylinder.:)

I remember an article quite a few years ago (2003?)...think it may have been a Dodge SRT-4 in Sport Compact Car? They put a big brake kit on it that shaved a bunch of weight and were actually able to see a measurable acceleration increase.

Regardless, shaving 20 lbs. of unsprung weight is likely impossible via any other route on these cars. Knocking 20 lbs. off the nose is also a very nice bump in the proper direction for overall front to rear weight bias.

In 8 years from now when these cars are selling for $10k and people are desperately stripping them down and drilling speed holes in them to remove every ounce, an unsprung weight reduction of 20lbs. will be viewed as a gift from the heavens. :D

Jeff , are those 17's?? They look great, im seriously considering selling my RPF1'S and getting some CE'S

Awesome! That bastid Jeff convinced me to go this route I think ;)

yea he convinced me too. Just gotta save!

Yep...the wheels on the S2000 are 17x8.5 +30 CE28N. Those just may be my favorite wheels. I have a 14" bronze set of CE28N's on my NA miata currently, and they weigh 7 1/2 lbs. each. I can literally change wheels with one hand...they're ridiculous. :D

Ordered :thumbup:

What rims are these?

AME Tracer TM-02

Uhhmmmm no..

They are Weds Sport SA-60M. Says it right on the wheel lol

:bonk: It LOOKS like the AME Tracer TM-02. Thanks for the correction though. What was I thinking?!?! :bonk::)

Similiar, yep :) I was confused when the guy asked since it was stamped on the wheel ;)

Brakes are on. Essex did a great job with the instructions. Only a pair of unexpected complications during install. I'll have them on the track tomorrow during the FRS86 meet at Autoclub Speedway in Fontana tomorrow. If you are around come by and say hi.

Here is a photo of the finished product. A longer review, install outline, and more photos are on my blog if you want to see.

I wonder which ones are lighter?








Looks great, cant wait to hear you impressions on these, im getting mine around the 15th. BTW what wheels are those?

Looks good... only if they made both front & rear brake upgrade. IF they ever do, I'm totally going this setup!

I will likely get a set of these in about 12 months after getting my car and then wheels to suit them :)

They will be, for show.. but why do you want more in the rear of the car?

IMO there's enough brake back there already, there is definately no need for larger heatsinks back there, it doesn't use all of what's already available.

I was working on a buddies Boss 302 yesterday and his car is running full Ford Racing 302R race car brakes, the rears used on the race car (and therefore his) are factory Boss 302 rear brakes, the fronts are massive full floating discs with 70 or 76 vane (forget) rotors and 4 pot Brembo calipers. Point being, only upgrade the rears if it's required IMO.

Well unless it's a show car, then upgrade everything for show points :thumbup:

Speaking from my limited personal experience having fixed calipers on all 4 corners improves pedal feel and modulation. Better heat dissipation is also a given. Performance improvement? Maybe only marginal in this car.

Would like to hear thoughts from Essex on this.

Certainly fixed calipers can improve feel and modulation, I would never argue that (and have stated it before). I would argue that it's going to be really noticable from the REAR of this car though.

Those are two of the reasons I've ordered the Sprint setup from Essex. The additional cooling from the rotors, lose of unsprung weight, cheaper pad replacements and longer pad life are others.

I really can't see myself ever bothering with the rear though, I don't believe we will get any great benefits from there and there is no need for additional cooling yet, the damn things don't even get warm enough on track to bake the paint off pads, it only takes a lap or two to bake the paint off the fronts ;)

I also doubt modulation benefits in general in modern cars, EBD I think will remove a lot of that benefit seen in older cars that I've experienced it in.

I'll find out soon enough hopefully - for the fronts anyways!

Jeff and I had conversations about this months before the car was released but I welcome his thoughts as well! :thumbup:

No, I don't need 4 pot in the rear. Just need 2 pot, more will be waste for this car.

Why I need/want 4/2 on this car when it's already good as is... I'm OCD like that. I cannot stand having different front & rear calipers set-up. Yes, I know that's totally "show car" concept... BUT I just feel I want 4/2 AP calipers.

skip the rear caliper upgrade and just make a 2 piece rear rotor to knock off the weight. This set up is great. More when I can type more and download all the video. I believe the car set FTD at the autocross and ran 2:00 laps on the Roval this weekend during the speedventures / FRS86 meet in Fontana. Great modulation, great heat dissipation.

Good to meet the many folks from this board that I got to talk to.

Best,
Matt

Mach V's "awesome" wheel. 17x9 at under 18 lbs.

Matt, any rubbing at the track with 17x9? Im considering selling my 17x8's and moving to a 17x9 to run 255's.

no rubbing on track. well, almost none. The rears touch just enough to turn the rolled fender black in a couple spots, but you can't see any evidence on the tire itself. It does rub at full lock in the parking lot. But I will run this setup again, and I have no problem putting my wife in the car. So no special knowledge needed to drive around issues.

We cant wait to get these on our BRZ this week !

JEFFFFFFFF ! :D

for me upgrading the rears just helps keep the factory distribution, if you take into account total swept area, proportioning valves, piston sizes, etc.

I was actually researching information on rear brake upgrades today and found this:

http://stoptech.com/technical-suppor...brake-upgrades

I'm a noob when it comes to the technical stuff, but I found it an interesting read. Visually, it'd be nice to have a rear kit to balance it out, but in regards to function, you theoretically should be fine with lines and pads (and some kind of matching rotor? (so you don't go from seeing a nice j-hook or drilled setup in the front to a plain ol' blank disc in the rear lol). This kit maintains or is close to stock brake bias, so it seems there's no real need to offset any changes with a rear kit. Right?

I don't think this reasoning holds water. If you are changing the front brakes with a kit designed to keep the same stock braking proportion, then changing the rear would in theory need to have the same braking proportion as the stock rears.

100% Agree. You beat me to replying to that, but this kit was definitely designed to keep the stock balance already.

Does Essex recommend rear brake bias adjustments via pad compounds if one was to keep the stock rears? Or do they recommend, for example 1 for 1, meaning if you use Hawk HP+ compound fronts they would recommend the same for the rears?
