Aww CRAP! So much for the 50" LCD 1080p flat screen! I hate this car!

Please post pics of the new caliper as soon as you can. Thanks for the great intro price!

as soon as i receive the front calipers i will be out...

my understanding is the new design calipers have been completed, are being painted, will be bench tested and shipped to me. the stainless steel pistons are in late stages of pre-production and should be in my hands in under 2 weeks.

there have been no compromises, and i am confident that it will be the highest performance brake setup ever offered for the FD.

warren and RB have done a great job not only in design but in getting it done so we can go out and burn up the track.

i invite anyone who KNOWS this to be accurate to chime in. the question being:

will a 93-95 caliper fit in a 99 caliper mounting bracket?

(the 99 caliper mounting bracket will not work as the RB rotor is larger in diameter.)

How come no one answer this quetion?

Basically, the only difference between a 99 and a 93 caliper is a new cast portion with the mounting tabs (longer on a 99). It appears that RB has cast a new part with even longer tabs for their rotor, so I don't see any reason why you couldn't replace that portion of the 99 as easily as you do the 93.

BUT, since nobody has actually bolted one together as such, that's why no definitive answer.

17" brake package caliper and bracket package v earlier 16" caliper and bracket. Other than missing cable retainer see a difference - no, me neither.

You'll find that's why the brackets are often for sale alone in Japan.

Net space for pads = 32.4mm(or max pad thickness of 16.0mm)

However one customer reported using EBC pad which has 17mm thickness and will not fit our two piece rotor.

Prospective customers are hereby advised to verify the thickness of brake pads and make sure the total thickness is not over 16.0mm and insure the caliper pistons are fully compressed in order to fit our front two piece rotor w/o fitment issue.
I just received my new EBC Reds. Talking about fronts only below!

Average thickness of pads were 15.7mm.
Now if you add the Mazda SS shim, they might be over 16mm. I do not have any extra shims to measure and did not want to pull mine apart until my RB kit arrives.

But the pads have a steel shim on them which is not needed with the Mazda shims. I removed these EBC shims which do not cover the complete pad width.
They measure .61mm. This leaves the naked pads with a thickness of 15.09mm. This should work with the Mazda shims which are thiner.

I wonder if the customer left the EBC shim on and also used the Mazda shim?

billyboy,

thanks for the post. does your pre 99 caliper fit in the 99 or later caliper mounting bracket?

I didn't personally bother, I know of two cars over here that have had the brackets imported from Japan and have reported no issues fitting the original calipers to the larger rotor.

I can easily check tomorrow if you want confirmation.

thanks again.

assuming that the earlier caliper fits the later extension bracket RB indicates it would be possible to offer a two piece replacement RZ rotor.

since it would require a special production run w it's attendant fixed costs it would take a number of preorders. it is not something that could happen overnight, but i am saying that it is do-able.

Howard- what brand/model rims are those? What offset?

Do they require spacers to work on the FD?

Curious where you got them from?

They look pretty lightweight. 2 piece wheel?

I just order a set of these brakes also.

they are Enkei Racing NTO3+M

i think they are the ultimate FD wheel w regard to track performance.

correct size(9.5 and 10.5) , strong, light relatively inenxpensive for a first class wheel.. they will require some rear fender mods but nothing drastic... see the Shine/Burnout rear fender lips...

front is 18 X 9.5. +30 19.4 pounds. fits w my rolled fenders.

18 X 10.5 rear is 19.6 pounds. (i wouldn't race on anything lighter). one piece. +40 offset


bought thru the board's Wheel Man Rishie.... who else.

OEM 16 inch wheels stock will not clear in the rear.

if you choose to file off the caliper re-inforcement ribs they will clear. the magnitude of the effect that on caliper rigidity is unknown.

if it was me and i wanted to keep the stock wheels i would grab the file.

it is your call.

Howard, how did you get the 18"x9.5" +30 and 18"x10.5" +40offset? Are they special order?
I know that Enkei only stock the 9.5" in +40 and 10.5" +30offset.

Howard, what tyres do you run (size/brand) on those wheels?

And why do they have two valve stems?

There are two valve stems so you can fill or release air and monitor the pressure at the same time.

toyo t1r 245/285

2 valve stems? good question, supposedly you fill on one and monitor pressure on the other according to Enkei.

yeah right.

i have gotten along fine w one valve stem so far so it wasn't a primary consideration
