Here's a topic that has been covered before, but I have a different twist.   I'm trying to improve the brakes on a few of my project cars (OK, one might be a M-II....) -but- I don't want to go to 15" rims (I think the cars look too modern with 15"+ rims).   I have one car that has unique 13" rims only available on that option package so I want to keep them on the car.  I got P205/60R13 BFG Radial TA's from Coker Tire already, so the tire problem is solved.   I also have 14" turbine rims on my '72 Hatchback that I'd like to improve the braking on that too.   There's some drag race brake kits with 10 or 10.5" rotors - but they are light duty.  Wilwood has a 11" brake kit that they say will fit "some" 14" rims, but Racer Walsh has a kit that uses Wilwood 10" dual plane rotors and calipers - they say this will fit 13" rims.  This kit isn't cheap ($1500+) but looks top notch & includes everything from spindles to bearings.   Anybody ever seen this on a street car?  Any other ideas for 13-14" rims??

Do you have the stock 9.3” rotors?  Any brake improvements?   My 72 has a v6, brakes are stock and OK.  My V8 car needs more in the brake department.
