Hi everyone, I'm a newbie in this forum. I come from Singapore but is currently living here in Shanghai, China. Just had my 2.0L AT Foci for about a month now. Done 1400km. Changed my rims to O.Z 17" and fitted 225/45/17 michelin tyres. Now I notice that I've lost some pick up with this new wheel setup. What can I do to compensate for this? Will changing to a K&N filter or a new exhaust system boost up enough horsepower to counter for the loss? Is there any other chinese forumers here that can enlighten me on where to get aftermarket parts locally here in China?
