Probably need another 7-10mm (Atleast) offset rotor. Anyone know of one which is 10.5" or bigger?

According to this thread the sport big brakes on some miatas is a 10.6" rotor.

You could also look into the products used by Rusman for his kit:

I think the advantage most guys at looking at is the calipers, not the bigger rotors.

As far as custom offset rotor sizes, have you thought about checking with brembo or some other OEM supplier?

There must be another off-the-shelf 4X100 sized rotor that might be close to the offset you need.

you can also redrill rotors for 4x100 if you can find something that fits with a different pattern

How much offset are we talking about? I might be down as long as it's not too much.

Any pictures?

M-Tuned

It probably going to need a 1cm spacer.. No pictures as we never went any further. We tried all kinds of different rotors also with no luck.

I am in for a 1cm spacer, how small of a run can it be?

I'd be in for a 1cm spacer as well, You used Corrado rotors right?

Depends on the price. 2 people would be very expensive as it would be the number of hours worked on project + cost of materials / 2.

The main issue to find a rotor which will work. We need a 10.5"+ rotor which has a 30-35 offset/inset (Not sure what it is called). This should help a great deal with fitting these calipers. Take a look at an RX7 rotor sometime. It sits in from the hub 45mm. 45mm is too much however as we would have ball joint issues. 30-35mm should be a good point for this to work.

The rotor would also have to be no more than 22mm thick to work also.

Son of a bitch.

Call Brembo and see if they've got something that would work for us.

Im really interested in the 11" diameter rotor AND calipers..

M-Tuned

iTrader: (6)

I would, but I am just far to busy to sit on the phone for hours with them. I'm still going to try and search online for rotor specs tonite. No luck so far.

elesjuan

Right on. If I can ever get the phone out of my ear today I'll see about giving them a call.

Just a thought...

Couldn't you fab up the brackets, then then we could adjust the offest depending on what rotors/wheels we have using washers? This should work as long as we can agree on 1 size of rotor to use. I'm thinking the calipers might fit under my wheels without spacers.

Sure, but we would probably need a commitment of 25 sets to do this. They don't want to create a part which has next to no market. (I'd probably have bashed up fenders if I put a 1cm spacer on my car)

What is the clearance from your stock caliper to the spokes of your wheel? You would need some crazy offset to make it work.

Ok I think I just found the problem Marc. Did you cut off the factory ears on the RX7 calipers? I reread the last 3 pages and I read you didn't intend to do so. I'm pretty sure that's got to be done. How did you have the calipers as far down on the rotor as possible with those ears still on their? Or did you already cut them off?

i would believe the offset of the rotor will be more effective in allowing better fitment for most people. To be more correct, the wheels' general offset wont have much of an effect; the design of the wheel will be the factor of fitment. Your wheel could have a crazzzy offset, but if the spokes of the wheel still are "flat" and not offset from the hub in someway (like K1 kosei's are) then it still wont fit without the use of a spacer.

this is becoming more of a problem to make this work, possibly more trouble than what i was expecting.

if you are able to find the correct rotor offset without any real fitment problems/requiring the use of a spacer, count me in.

Won't work either way. With our without ears. The issue is the front part of the caliper is HUGE! ETD measures and models everything. They spent quite a lot of time on it with no solution. Yet...

Take a look at an Rx7 rotor and a Miata rotor. You will see the difference and everything will make sense.

You my friend understand 1000000% We need a different rotor, or a fender bashing spacer

i read more about why they did this for the japanese kit, but theres no real reason IMO. its possibly to make the rotor sit closer, or maybe it was easier for installation? either way, making the correct bracket will make it fit either way, but it seems that thy just did this way to cut production costs on the brackets themselves. if you look at the japanese brackets, they are just a flat metal piece, easily fit. possibly if you used the stock "ears" they would need to offset the bracket themselves, and will possibly require the use of nuts to hold the calipers due to the lack of a screw in point on the bracket themselves (obviously the stock bracket on the FC has these.

Well I don't have any RX7 rotors, and my RX7 calipers are not here, but I don't see how you got the caliper all the way down onto the rotor with the factory ears on it. They would hit the stock mounting ears on our hub. How did you get the caliper all the way onto the rotor is my question. Did you index it clockwise or cc wise so that they didn't interfere with one another? I fully understand what your saying about the RX7 rotors having a different offset, so don't get me wrong. I'm just curious if you had the calipers as far down onto the rotor as possible, as that moves the caliper further away from the perimeter of the wheel.
