OK everyone lets talk reality here. For those of you worried about the slight performance disadvantage of 18" rims, maybe you all should be driving something thats not a Corolla. A Corolla Sportivo is not a track or strip weapon without some fairly costly modifications all round. They are a road car designed to give the driver the option of a spirited drive, should they desire to do so. For day to day use and the odd few squirts up to 8000rpm the 18's are fine. I've noticed very little loss at launch and can still land 1-2-3 lift. evl_50a - If you like the 18's, go with them! I havent seen a set on a Corolla yet that looked bad. However, if your trying to shave tenths off your quarter mile times, have a think about the cash your going to be forking out for wear and tear and general abuse to the car. You'll be spending alot more on that than the extra cost 18" tyres will demmand! Final note - no offence intended to any of you guys out there with earlier opinions, respect to you guys running your cars round the tracks and down the quarters! But really how long are you going to be able to use them for the daily commute if they're out being thrashed every weekend?
