Yeah mate 17"s all the way. I had 18"s on my VT and the ride was like getting yr spine ripped out with needle nose plires. It also didn't help that it had FE2 tho with the 18"s. I got 17"s on my magna and the ride comfort is the same as the standard 15"s plus u still get that look of big wheels. The tyres are also a lot cheaper too. Sometimes people mistake my wheels for 18"s! Plus they'll be better 4 loading up yr tray as they can take more weight (not much more but still) as the profile is higher. Besides, if you get 235/45 R17 tyres like mine, they'll make the car handle better (more grip) and you'll get the wide tyre look too!
