New ISF owner in Winnipeg Manitoba Canada

Hello everyone, Bought a used 2008 Lexus ISF last year and just started to really enjoy it this year. Just installed the K&N Cold air intake on the car and it's absolutely fantastic! Can't wait to get the Sikky headers and SRT True Dual exhaust installed either! Looking to upgrade the factory wheels to some aftermarket wheels but the threads I've been reading sounds like it's not going to be an easy task to find a good looking set of rims that will fit. Hope to gather alot of tuning information from the rest of you as I want to really make this car a force to be reckoned with here in Winnipeg. Great site btw. Thanks Ted
