the difference is 18" looks normal, and 20" screams ghetto

You will turn an already crappy gear ratio (3.31:1) into an even crappier one. If the wheel/tire combo weighs more.. that's another hit to performance.

Using Drag Racing Math:

For every 100lbs of non-rotational weight you lose, you lose a tenth off your quarter mile. (this would be from removing a spare tire, a jack, a seat, ect.)

For every 10lbs of rotational mass you lose, you lose a tenth off your quarter mile. (this would be from lighter rims, a lighter driveshaft, ect.)

So with this in mind, if you add 10lbs of rotational mass, you will GAIN a tenth on your quarter mile. in order to find out how much you would gain, you would have to weigh your stock rims, weigh the 20s, then subtract the weight of the stock rims from the weight of the heavier 20s.

However, horsepower measured at the rear wheels will suffer only slightly in a V6 application as compared to a higher horsepower application. The main reason for the slower time is all the extra weight that your engine has to spin to get moving.

to op it is honestly personal preference. just take a look at different s197's with 20's and 18's and decide which you think will look better on your car.

I think if I had a GT, I would be ok with 20's.

I'd like to get the new 18's that come with the 2010 Mustang GT. And put some Pirelli P Zero's on them too. Will they sell me GT tires, by the way? Or will they force me to get the option 18's from the V6?

Also, what's the right amount to drop the V6 so it looks good? I hate it when people overdrop it to where it looks like the top of the tire is gonna rub the wheel well.

And is it the dampers or springs that need to be changed to get the right drop?

And do I need to get new brakes if I'm upgrading from 16's to 18's?

Thanks for answering my noob questions.

I guess I'm rolling in a ghetto mobile since i have the 20" shelby razors. So, iyo shelby is producing ghetto cars?

20s are not ghetto unless you leave out the body kit and lowering the car. Then I can see the ghetto-ness of it. If you are worried about performance....why? You're car can only go so fast. It's not like you race all the time is it?

Just get what you think looks the best IMO

Its not the rim size that fills up the FORD fender well gap.
Its the diameter of the tire on said 20" rim and the Revs
per mile for said tire mounted on said rim.
