Large 268 mm disc brake rotors from S110 or 280ZX can be adapted to B310 (Sunny/210) or A10 (Stanza/510) struts - and still fit over 13" wheels. These are from the rear of early 280ZX and are larger than the late 280ZX rotors. Swap developed by Doug Morrisun.

Overview
Works with stock master cylinder.
This setup fits over most 13" wheels. Wheels with inside diameter less than 11.7" won't fit.
Rotors: * 1980-1983 S110 (Gazelle/Silvia/200SX/240RS) * 1979-1980 (early) 280ZX rear Calipers: 1983-1990 Nissan B11/B12 (Sentra/Sunny) Adapter brackets: Morrisun Productions Brake hoses:
As these rotors fit over the hubs, it adds about 13mm to the total track.
B310 hub diameter: ~154 mm S110 rotor inside diameter: ~145 mm

Note: D275 is used by the factory Sunny Truck Disc Brakes, used with 208mm rotors to fit under 12" rims.
Machining
S110 268 mm rotor & caliper requires some machining. But it gains ventilated rotors suitable for racing applications.
Stock hub is too large to fit inside the rotor hat
Machine outer diameter of hub down about 1/4"
Now it will slip on
Adapter
Buy or fabricate caliper adapter bracket to fit the 130mm bolt-spacing caliper to the 75mm bolt-spacing struts.
Adapts the B12 Caliper to the B310 strut.

Brake Hoses
The calipers require banjo-type hoses. Many different hoses can be used. If you are buying new hoses, we recommend these common Nissan hoses:
1989-1994 Nissan S13/S14 "240SX" RockAuto.com $5 each
Additionally, this set allows the choice of running calipers either in Leading or Trailing positions. Switching position is sometime done with extreme lowering. This is done by switching struts from side to side for mounting calipers in Leading position.
Lug Studs
Since the rotors fit over the hubs, they add about 1/4" to the mounting face of the wheels. So you *may* need slightly longer Wheel Studs, which are common from a wreckers or buy them new.
