Large 268 mm disc brake rotors from S110 or 280ZX can be adapted to B310 (Sunny/210) or A10 (Stanza/510) struts. Swap developed by Doug Morrisun.
Contents |
Overview
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) 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
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.
Adapts the B12 Caliper to the B310 strut.

Specs

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.
