You can also check THK motors sa Banaue Q.C. I changed all of my shocks for my galant MMC and saved PHP 2,000 worth of parts (total costs for all shocks is 10,400 all KYB - liquid and gas for F/R)!

For Services, you can check PRIME MOTORS, just after Buendia in SSH (they have also parts there, but more expensive than THK). These guys are really experts in Mitsubishi Cars. I've been relying on them for the past 12 years (including our old car back then, Galant colt '76).
