More practical or less practical to get new wheels?

[boog]

I may be a new yaris liftback owner sometime soon...i test drove the car yesterday and i was surprised by how slow it was(i was impressed with the overall 'feel' of the car tho) and i was thinking about getting some 15" maybe 16" lightwieght wheels but i just can't see the justification in such a small car with so little power...what do you guys think? even if i auto-x'ed it, i think i would just go to www.vulcantire.com and order some Falken Ziex tires for the 14" steelies. That would get more desirable traction and then i could just get TRD suspension upgrades and be done with performance mods until an engine swap kit fro hasport or someone comes out......sure, new wheels would be a little wider for better traction/handling but it seems like the car would suffer too much from the added wieght of the wheels...how do you guys feel about this, are the steelies heavy?

here's a pic of my car right now...the little rotary motor runs great but the rest of the car has run it's course and it's time to get a cheap/reliable car: ; )
