18's or 20's
 

So I found these wheels but they only come in these two sizes. I Didn't want the 20's cause of them slowing the car down. But do y'all think the 18's would be too small? Thanks for your input!

Why would the 20's slow your car down the wheel and tire aren't that much more heavier than the 18's.

The larger the radius the more power it takes to rotate the wheel completly

Hmmm those look heavy in any size, what are the specs?

This may sound retarded but aren't tires for 20" rims thinner than tires on 18's? Tire thickness will offset any radius changes due to rim size won't it?

18x9 18x10, 20x9, 20x10. I can't get any info on weight. although the front lip is 2 in. and the rear is 4 in.

The thinner the tire the less tration you put to the ground. Also sthe thinner the tire the harder the composite

Find the weight and offset, those are key before proceeding any further.

Will do!

really typical wheel style. if they dont have the size and offset you want, then just get a different brand.

I can not find any weight info, and the specs they do have do not show the off set I want. Even though discount tire gave me these specs. I really wanted some bronze wheels but I can't find any suppliers the wheels that are on here are 3 piece forged, way out of my price range I don't want to spend more than $1500 on my wheels.

that is why I wrote this, the difference is very small.:tiphat:

Ku but if I did go with the 18's would they look weird?

This is only true if you don't correct the tire profile, other than that overall weight from the tire/wheel combination is what matters.
