MY 04 sti 225/45/17 35 front 33 rear (feels good)
iebachs,
ecu tech
whiteline anti roll front and rear with linkage

 

That's what i've had on both my 17's & 18's.Experiment occasionally with 36F 34R but find 35/33 a good balance.

 

I just use 33 front 31 rear, although lately i've had them at 33 front and back so the rears last a bit longer...doesnt really make a huge different to be honest, except being a bit more tail happy when wet.

 

Whatever you desicede make sure your checking pressures from a cold tyre..

The difference from cold and, even two steady miles down the road, is about 3psi and >6psi if you've been giving it some..!

Use a good gauge also goes without saying.

FWIW my 225/40 18's run a cold pressure of 36/34 (f-r).

 

Another 35f 33r here, although there is no difference in 36f 34r.
