I have big 18s that are heavy with tires. I am wondering, should I sell those and buy some nice 15s that would be much faster and more fun to drive? I would also save money with the 15s and they would be great for the track. Any suggestions?

 

It sounds like you have made up your mind, get the 15".
You say they are nice, you'll be able to go faster and you'll save money. Whats important is that you'll like them.

 

The only thing is the 18s look so damn nice and sporty. I don't want to look cheap.

 

get 16s then..sometimes you have to compromise the vanity for the speed.

 

but i like to be fast. I think 16s would be to heavy.

 

Have you Reserch how much difference in quarter mile time if you go with 15inch against your 18's. If its 1 - 2sec. hell go with 15's!!Sell your 18's and buy more mods

Not that you dont have enough yet!!

 

Then how about going for looks and performance!!!!

Get some ultralight weight rims like SSR Integral, OZ Superleggera, Enkei RPM2, Volks gramlight, RH CP08 and the list goes on...... It all depends on how deep you want to go into your pocket.

 

I was looking at 15s that were around 13lbs. Do those compare?

 

You can get some 17s or 16s that have that same number of lbs on them. With you having 18s and looking ot go down it shouldnt go too much further into your pocket. If you get 16s they look sportier than 15s not so dwarfy either and still you can have a fast car Its just a matter of looking
