Is there a brake that fits behind a 15" rally, but still looks good behind a 20"?

probably not. Maybe a 6 piston on a 11.75" rotor. (wilwood)

I've seen a couple of C2/C3 Corvettes running either the OE or the Wilwood D8-4 (http://www.wilwood.com/Calipers/CaliperList.aspx?subname=D8-4) calipers with 20's that didn't look bad IMHO...maybe just a little ridonkulous. Those rotors are 11.75" diameter and 1.25" thick. I'm not much of a fan of the OE calipers dues to the piston seal design, however the Wilwoods being almost 30 pounds lighter for the full set makes that a pretty easy upgrade choice.

So once I go with real brakes, no more rally's!
Dang...

I still wonder how the NASCAR folks get giant brakes behind a 15". Herb Adams also had big Hurst Airehart calipers and Stock Car Products spindles under 15" wheels years ago.

the stock car steel wheels are a deep bell design to clear bigger brakes, 12.190 rotors were the biggest ones you could fit in one of those wheels, I think now with changes in caliper design they can go as big as 12.32o rotor dia. in the 15" deep bell wheel.

You don't see many rally's in stock car racing. While the rotor diameters are limited due to the wheel size, they run massively thick rotors to make up for it. The short track setups are nothing short of amazing...it's like 10 gallons of rotor/caliper inside of a 5 gallon wheel. :bananna2:

Check about half way down for 15" clearing brakes

You cannot see the brakes behinde Rally wheels anyway. I would do one of our Rght Stuff factory style kits with drilled and slotted rotors and powder coated calipers. Cheap and effective.

Or your next step is Wilwood or Baer 11" kits, but you won;t see them at all.

Cool thing about 15" wheels is your MOI (moment of inertia) is so much lower you can easily get by with a smaller brake and still have excellent braking.

I was looking at something like this as well, but behind a 16" rally.

Is the "Right Stuff" stuff made in the US?

Does anyone have the new Baer SS4 front and rear set up?

Not many options!!

None of the aftermarket factory style brakes are Made in the USA. Right Stuff makes some brackets and parts here but the majority of it is made off shore. Right Stuff does have the best QC requirments of all the brands I have seen.

Baer and Wilwood do all the machining here in the USA.

We just shipped a small wheel Baer kit last week to member Falcon65, I look for some pics from hin very soon

I also received the new Baer kit a couple of weeks ago for my Nova. I cannot believe the quality of this kit.

12.19 kits are out there from wilwood that will clear a number of 15" wheels, and the whole kit is under $1500.

However, to get in the 12.32 range, your talking primo competition parts that cost big dollars. Like $3800 per caliper; http://wilwood.com/Calipers/CaliperList.aspx?subname=STR6 ,how bad do you want big brakes?

Not really. My solution to this problem Running big brakes under my 17's, then doing another easily swappable setup for when I want to use 15" race wheels.

Easily swappable is certainly in the eye of the beholder. I'd have to admit I'm too old and/or too lazy to want to swap out rotors and brackets everytime I wanted to swap out wheels.

But seriously, the difference between the overall appearence of a 12" vs a 13" brake kit is only .5" on each side. Does that much material make that big a difference in the appearence of a rotor? Guess my eyes need to go in for some re-calibration.

True. If it was just for looks I would say it wouldn't be worth it. But the only time I would be swapping them out is for track weekends. So, the difference would be worth it for me.

Your right in Nascar country....get a race shop to fab you up some mounts and put these babies on......these prob wouldnt work due to the rotor thickness reqd but you get the idea.....theres a guy I talk back and forth with who road races in V8 Stock Car....buys all his parts off Ebay
