Guys what's the pcd of the optra wagon 06. It's 4 holes. Tama ba 100? I'm planning on upgrading the wheels from 15 to 17-18in.

Also, I've read the threads about the ECU programming of the Optra. But I know that it's mostly for old model Optras. My question is, were they able to fix the ECUs already for the 06 Wagons or not yet. I bought mine 2nd hand so I don't know about the history. But from the initial run, it was about 7-9 kms on city driving, manual tranny.

I'd like to know if there is any club I can join so I can buy parts for the optra like skirts and spoilers.

Thanks!
