Default ITR big brakes not forgotten...

Just in case you were wondering where the 4 piston brakes were, they should be ready in about 2 weeks. I have the rotors and hats configured and will be ordering the hats as soon as I get the best price from my local CNC shops. I still need to finalize the bracket, but will do that once I have the rotors and hats.

Specs are:

11.75" x .81" thick rotors with 6061 T6 Aluminum hats, hard anodized black
grade 8 rotor/hat attaching hardware
Superlite IIA calipers

These will fit inside a 15" wheel, although I don't know if they will fit the stock wheels due to the caliper overhang. I'll be test fitting them on an ITR to make see.

I am offering these for the introductory price of $799.95. You will need to buy pads of your choice but that's it.

Also in the works is the 11.4" rear upgrade. I'll be test fitting this too in the next 2 weeks...

will our stock MC be able to handle the upgrade of front and rear?

The 4 piston caliper piston area have been sized to match the stock caliper piston area, so no change in pedal travel will be noticed.

The stock rear caliper will be retained, as a spacer bracket to move it outward is the only change, besides the larger rotor.

Oh and I am working on the 2 piece 11.4" rear rotor now too.

will we need to upgrade the proportioning valve?
also, will regular ITR pads fit into the calipers or do we have to get customs ones?

soly fo all da Q's.

Oh hell, that's no fun. Only way to significantly increase clamping force is to increase piston area. Screw what Stoptech's marketing propaganda says about piston size. I've driven both types of setups, and only larger piston and rotor setups significantly increase braking power, and shorten braking distance.

I do like 2 piece rotors though, if

a) safety wired on back, or nut/bolt combo. DO NOT RUN W/O SAFETY WIRING.
b) true floating rotor design (Stoptech has some killer rotor and hat designs)
c) more rotor mass than stock.

I'm sure I'll get flamed, but flame on!

Warren, did you ever see my set of Stoptech 2 pc Rotors?

I have yet to install these. I'm waiting on stronger pads.

Thanks,

Yosh- The rear calipers will use the stock pads, while the fronts will need pads for the Superlites. The prop valves can remain the same.

Warren- While I have spoken to Bob at StopTech many times regarding the rotors and such, it has never come up about the piston sizing. I base my piston sizing on engineering principles as stated in my brake design texts. Clamping forces do play a part in the overall increase in braking ability, but they take a back seat to overall rotor diameter when it comes to actual brake effectiveness. I can certainly size the calipers so that the clamping force is increased, but I try to keep pedal travel approximating stock travel as most people are used to that.

As for the rotor type, they are not floating, at least not right now. I agree the StopTech design is an excellent one, I have them on my car now.

The rotor will be held to the hat with bolt/metal locknut.

The overall mass of the 11.75 rotor is somewhat less than the stocker, only because of the aluminum center section. The actual rotor friction surface is more due to the increased diameter...

fastbrakes: Just a couple of things that I wanted to address. I think the calipers on the rear could also use upgrading in addition to the larger rotors. The reason being is, the stock calipers currently wear the inside pads VERY unevenly practically to the point where one part of the pad is virtually untouched, and the other end is down to the metal. I have also noticed that I have to change rear pads at least as often as the fronts. I understand the larger diamter rotor may prolong the life of the pads a little bit due to the reduced heat, but there is still the uneven pad wear.

Also, about the 2-pc rotors, I would definately be interested in them! When do you plan on having them available?

fastbrakes,

Questions, I have been doing allot of research regarding brake upgrades using Wilwood stuff.

1st - Why not go for a 1.25" width rotor? Wilwoods specs on a 11.75x1.25" straight vein rotor is 8.9lbs. This is already lighter then stock. Would not the extra width improve cooling, something our brakes need badly.

2nd - Why not go that extra bit further and use the Billet superlite design. They are lighter, look better, and are available in differential bore. In fact the surface area of the 44.5mm + 35.1mm bore calliper is only off stock by 1%. All these benefits would make this a no brainer unless there is something I over looked.

3rd - I thought that due to the 3.5" mounting centres on the superlite series callipers they could not be fitted to the Integra unless the knuckle was modified. Is this just a myth or what?

Regards,

Oh yeah, I'm very interested in this!

BabyNSX, why dont you take the extra step and go further and let him do his own thing.
I wasn't trying to offend anyone just ask some questions that I had that's all. This is HONDA-TECH after all.

As for taking the next step, I had fully planned on it but question 3 had me stumped. I'm not interested in modifying my knuckle to make this work so if Fastbrake has a solution for this I want to know, hence the question.

Besides, if my asking the questions results in Fastbrakes developing an even more effective system (even at extra cost) then I'm even more interested!

Regards,

I have a rear upgrade kit from FastBrakes for my 99 Si. The only think I've asked him to check on is for a LAGER caliper that fits over the entire surface area unlike the stock caliper which only covers half the large rotor surface. I realize that it will not make that much of a difference, but maybe a larger rear caliper would make a little diff. Plus a rear aftermarket caliper would look nice too!
Oh and we've tried to find a larger brake pad to help use more rotor surface but had no luck.

Brian - any luck yet with the larger rear caliper or aftermarket rear caliper for me?

Plus I'll be doing one of your 4 bolt ITR fronts soon! Maybe this new set up might work for my 99 Si - any feedback would be great! Thanks, Cliff

Hey Fastbrakes it's Clint I can help with the test fit if needed. I've been meaning to come over to show you the intake setup and talk about some rotors for my car.

Sure would make them more marketable if they fit OE wheels...

I will be looking into the use of another caliper, but haven't had the time lately. If I can find one that has a parking brake and will fit over the 11.4" rotor, I'll use it.

Good questions, here's some answers.

1. The 1.25" rotors don't allow any room for the caliper to fit. I have the 1.25" rotors and tried them first. A 1" rotor is plenty big enough for up to a 2800 lb car.

2. I am trying to keep the cost down with the kits and will be using the Superlite IIA's or Billet NDL's if possible. Another problem is the width of the Billet Superlites. If they fit a wheel I will be glad to susbtitute them for the Superlite IIA or NDL...

3. Myth, as I have done it It wasn't easy believe me....but I finally figure it out.

I'm trying to make them fit as wide a variety of wheels as I can, but sometimes it just doesn't work out...

Just reading the latest issue of Grassroots Motorsports that came in the mail a day or so ago. There is a short review/article about fastbrakes on page 144.

Just FYI.
