I did the final test fitting of the 4 pot caliper/11.75" rotor with the stock 15" wheels and it all fits perfectly. I am taking orders for the next batch of rotors scheduled to be made after Jan 1. I have a couple of pics if someone wants to post them.

I have been able to trim some costs and as a result can offer the next batch to H-T for $720 plus shipping.

 

I'll host the pics. email to ed.sackley@us.bosch.com

Pic?

Where are the rotors from?
Easy rotor purchase?
Are several pads available?
Color of caliper?

Will

 

I bought the kit and he told me i could get carbotech pads or EBC pads.

 

Can we get more detail info on this kit?

 

Yeah, uhh..... what he said!

And do these really decrease braking distance? Empirical evidence?

 

Man I really want that kit.

Brian: Can we get the rotors cross drilled and slotted? would it compromise structural integrity of the rotor?

 

All in all, that sounds quite reasonable.
I like the stealthy look of those Willwood calipers.
What rotor blanks are used in the kit, and what's the availability of replacement pads.

Thanks, I'll probably need more brakes ... to counteract the effects of the turbo!

 

The kit consists of:

Superlite 4 pot calipers
11.75" rotors (replacements available from Wilwood for approx $70 each)
Aluminum mounting hats, hard anodized
mounting hardware, etc

Pads are available from any of the perfromance pads makers, pick the ones you like best

Cross drilled/slotted rotors are available for approx $100 each

Billet calipers are available for an extra $75 each

I don't do any testing for stopping distances because it is too subjective. These brakes are designed to slow the car down from race track speeds without fading, and with consistancy, time after time.

The pic shows the edges of the caliper trimmed, this was done during an early test fitting, now there is approx 10mm of clearance between the caliper and the spokes.

 

Ok, then how about an upgrade for the rears? (Dont want the rear outrunning the front on hard braking...)

 

Is there any chance that there is a way to get the rotors to fit in conjunction with the Spoon calipers for those of us who have the Spoons already? A larger diameter rotor is always helpful.

What is the thickness of the rotor compared to the stock one.

 

Just use better pads in the rear!

 

.....Then they are in abs mode while the fronts aren't! Still tries to outrun the fronts...

 

I know the new rotors thickness is .81".. dont know about stock thickness.

 

Ken, I'm running the R4 pads all around right now.
Seems either the fronts do most of the work anyway, or the rear pistons are just sticking a bit before gripping/biting.

At first it seems like you'r saying that you'll be needing "more" rear brake (after upgrading the fronts), now it seems you might be saying there will be "too much". Which is it? I'm just trying to help out,... Ed.

 

You run the r4's on the street? How about that deadly brake dust, eh?

I'm pretty much playing devil's advocate 70% of braking is up front anyway:

The buddies of mine who have upgraded to itr or gsr calipers front and rear on their hatches and eg coupes have the problem because the rears lock up and drift on hard braking. Fronts work really well. I'm wondering if I'll have a similar problem (will this affect bias?) if I upgrade the fronts and not the rears... Just don't want some unexpected rear swing on the track or street...

I'm sure others on here will want some more even wear in the rear (although 1 piston in the rear can't be that bad)... Or maybe they will want some bling bling rear calipers and rotors...

I just want the whole picture, pro's and cons. for you help Ed. I'm glad I'm not the only one who drives fast all the time!

 

Brake dusting isn't noticable lately (I've been rinsing the car off more oftet lately ...), and one of the keys to doing R4 pads on the street seems to be to use good judgement in allowing some distance to roll to a stop, and then just step on the brakes (my now well worn cryo'd rotors may be also be less abrasive than stock or non-treated ones).

Brake swaps (esp between different weights of vehicles), pose their own problems ..., usually stemming from the non-use of the proportioning valves from the original system. I'll probably encounter a similar situation when I swap my teg stuff to my crx (whoohoo! 4wheel disks on an 85 Si DOHC Turbo). I don't think this will be a problem (as far as upgrading the fronts only) on an ITR. After all, they only seem to upgrade the fronts on WC cars (but I'd bet they use race pads all around). HTH

P.S. promised George I'd leave, but wanted to get back to you on this one! /ed

 

I would at least run better pads in the rear (compared to OEM pads) if you upgrade the front. I glazed some rear pads this weekend and the difference in braking was so noticable I thought that I boiled the fliud horribly. As it turns out, I didn't boil the fluid at all, just glazed the hell out of the rear pads.

 

Brian, what kinda weight savings we looking at with this modification?

Lookin to make the 2320lb. welterweight a tad bit lighter....

 

yes Brian,

I am also interested in the weight savings of this kit. Also could different rotors be used, such as Stoptech?

 

Nice work Brian! Looks good. Your missing some lugnuts BTW

Would this work on a 99 Civic Si, what about 92 Civic CX hatch?

 

Brian,

are these only for the ITR or are they available to GSR and LS owners as well?

Is this a H-T special only?

 

how much for just the calipers

 

...any hopes for those of us who would prefer at least a 1" or thicker rotor? I like the extra mass and larger cooling vents... Hell, a stock diameter 1.25" thick rotor would work wonders for fade resistance...

Mike K: Weight savings is approx 10 lbs per brake assembly. The rotor/hat weighs about 9 lbs and the caliper weighs 7 lbs with pads.

This kit is designed to fit all the cars equipped with the 10.2" or 11" brakes( 90-2001 Teg, Civic Si, EX, ITR) It will also fit the regular Civic with different brackets.

Calipers cost about $135 each...

Thicker rotors for the ITR(in stock 11" diameter) are available in the form of my 2 piece kit. These fit the stock calipers. I can make up a 1" rotor in the 11.75" size, it will put the 4 pot caliper close to the spokes...

Someone asked about putting bigger rotors on cars with the Spoon calipers, it's possible but I'd need a caliper to do the test fitting...
