Current STi (05-06) hubs, although a 5x114.3 PCD, retain the 25mm upright to shock width. SVXs are 30mm.
However, my current thinking is to upgrade to pre-Brembo STi brakes. These were 4 piston fronts and 2 piston rears.
For the fronts, I plan to machine down the SVX disc to about 294mm in diameter (down from 301mm) then bolt on the 4 pots to the front as the caliper spacing is the same I think.
For the rear, upgrade to Lexus LS400 rears discs with the 2 piston rears bolted on again.
That's the theory...untested at this stage.
