Anyone know what the rotor dimensions are for the '99 Type RS brakes Fr/Rr?

The '99 FD calipers and rotors require 17-inch wheels, so I presume the rotors and calipers are larger than the '93-'95 FDs' brakes?

Anyone know if '99 Type RS backing plates are needed to install the '99 Type RS rotors, or will the '93-'95 backing plates work?

Thanks in advance!

in the rear you need the rotors and caliper mounting brackets.
in the front the rotors and calipers are different

I ordred '99 Type RS calipers and rotors for the front and rears from Mazda Comp. They said that the '99 Type RS brakes are completely compatible with the '93 to '95 FDs mounting hardward? The only parts I ordered were the calipers, rotors, and the 4 front caliper pins...I wasn't aware that I needed anything more than those parts?

I wondered about the backing plates, because I wanted CWC's Widefoot front brake ducts, and didn't know if Duane's ducts would work with the '99 Type RS brakes?

Sorry, kind of off topic, but I was looking at the new Bathurst Type R specs and it comes with 16" wheels. wtf?

How much are those Type RS brake system?

forcefed1

If they are the RS brakes and rotors, then they are larger then the ones you have now. Im assuming that is why you are interested in doing it this way.
here is a good page on the entire 99 in general about 1/2 way down is teh brake table

I would think it will bolt right up but you will probably need the right pads.
let us know what you find. Im interested in this as a brake upgrade whenever the current system dies.

what are you talking about duane's ducts?

SleepR1

forcefed1,

Sorry, Duane Krumweide's Crooked Willow Composite Brake Ducts

forcefed1,

Thanks for the link...the front and rear rotors are 12.4 inches in diameter compared with 11.6 inches. Front rotor thickness is 1.25 inches, compared with 7/8-inches. The rear rotor thickness is 0.79 inches thick, same as the current American FD.

Neo_omega,

Fr/Rr rotors and calipers, plus the front caliper pins runs $1474.20. Add $60 for the DOT steel braided brake lines plus shipping.

Mazda Comp is out of stock of front '99 Type RS calipers, so I've got those on emergency air order from Japan!

I just bought a set of 17,9 SSR Integral A2s with 255/40-17 Yokohama AVS Intermediates for $1710 shipped from South Bend to Indy.

The total cost to run these '99 Type RS brakes when factoring in new wheels and tires is: $3244.

If you have 17-inch wheels already, then you're that much farther ahead tham I am!!

Forcefed1,

I spoke with Sylvain Tremblay of Speed Source (954-578-7071), and he says the current pads for the FD are compatible with the '99 FD Type RS calipers and rotors (woo hoo!).

Note that Sylvain has switched to Porsche Carrera. He hasn't campaigned an FD race car for three years...BUT he does prep FD Rx7s for racing. His suggestion is to run Hawk Blues all around with Castrol SRF. The '99 FD Type RS brakes (using only the fronts, mind you), is the most cost effective brake upgrade available for our FDs--in Sylvain's opinion, which is pretty damned good one!

The Type R model has always come with 16" wheels since '92. The bathurst model is based on the standard Type R so its no surprise that it still has 16" wheels. The Type RS, by comparison, has had those 17" 5-spoke wheels standard since '96.

Mr Seven

Hey SleepR1, so you decided to go with 255 rather than 245 in the front after all? Any rubbing so far?

SleepR1

Off-topic to Mr. Seven:

Yeah, it was strictly a budget constraint. The 255/40-17s were $106 each and the 245/40-17s were $111 each (? go figure ?).

The Yoko AVS I's are 25 inches in overall diameter, with 10.2 inches of section width mounted on 9-inch wide wheels. With the SSR Integral A2's 45 mm offset (1.8 inches), the math works out to 3.3 inches front space and 6.9 inches back space all the way around. As we discussed in the wheels forum, 3.5 inches front space and 7 inches back space is the max front wheel position clearance for FDs with stock style springs.

Now we'll see if the numbers translate into reality. The wheels/tires shipped from South Bend TODAY, so I'll have them on the car Mon/Tues Next week.

I hesitated on other 255/40-17s as most were taller than 25 inches, and about 10.5 inches mounted on a 9-inch wide wheel. The Yokohama AVS Intermediate is apparently shorter and narrower than typical 255/40-17s, especially compared with Bridgestones (which tend to be wide for their sizes).

Full report due on the suspension forum next weekend, after driving around for a week or so on the new road setup.

neo_omega

how many pot is the Type RS calipers?

SleepR1

neo_omega, 4 piston in the front and 2-piston in the back. The setup is just a larger version of the US Spec FD cars' brakes and rotors, according to Sylvain Tremblay of Speed Source.

forcefed1

When you need to replace the calipers, are their any options? Are you stuck with the ones from mazda comp.
how much was one caliper? for the front

SleepR1

forcefed1,

It's $843.20 for the front brake calipers and front brake rotors, and 4 caliper pins. I don't know what the each part costs, as I don't have the invoice yet.

The parts are all replaceable, and the rotors are MUCH cheaper than M2's $220 each for their $4000 4-wheel brake kit!

The '99 FD Type RS's calipers are Mazda factory pieces...they're larger Sumitomo calipers, basically larger version of the US spec front brake calipers. The '99s are thicker to accommodate the 1.25 inch thick rotors.
