Hm. The 2 pots have a larger effective disc diameter, compared to yours anyway. For the 290mm rear folks (US/Cad/high-spec) it's aesthetic - which is why I haven't done it yet.

Yes, you only need piston area on one side with opposed piston calipers. And also yes, there is a very slight bias shift rearward with the subaru wrx 4 pot front.
EDIT: I'm wrong on the bias change, the rear FHI 2 pots shift bias forward. Front FHI 4 pots have no effect on bias. - Andy Last edited by Racecomp Engineering; 06-07-2020 at 05:27 PM. |

The brembos get you a much bigger heat sink, but more of a shift in bias. - Andy |

The FHI 4 pots have smaller piston area than the stock 2 pot sliders, using the same effective diameter - hence they move bias rearward.

Just switching to the 326mm disc should multiply the applied torque by 1.1 because of the extra distance from the point of rotation to the point of applied pressure. I wonder if our calipers would fit over a 30mm wide rotor? |

The OEM rear calipers should work. Ours is 290x18, a 2004 STi's is 316x20. Just need to make a bracket for the caliper. |

You will need the full assembly from the front of the LGT, including dogbones. I don't recall where the bleeder is, but you might have to swap the calipers right to left to get the bleeders in the right place. Both pistons should be the same size in the caliper, so no concern with flipping them side to side.

Also @gramicci101 you could do this: http://www.knsbrakes.com/c/caliper-items/2279
Nissan Z32 adapter bracket, Nissan Z32 caliper, LGT rotor. |
