Has anyone tried putting 20's on their V6? I'm curious why Ford made the wheel wells so damn big that, in my opinion, you need 20's in there to really make it look like a tight fit. I think there's still too much wheel gap with 18's. And I currently have 16's, so you can imagine how happy I am with mine.

But back to the 20's, is there not enough power in a V6 to make the 20's worth it?

the diameter wont change a whole lot, it needs to be lowered but the weight of the rim will obviously increase. I have driven a stock V6 with 20s and I notice the difference. You could counter the loss with a CAI and tuner later. IMO V6 doesnt look good with 20s unless you have a body kit or something.

sure... there's enough "power" to have 20s on a sixxer will there be a noticeable difference in drivability... undoubtedly yes. if you think 20s will look best then i say go for it. cuz personally i think they look good and you DONT need a body kit 2 have 20s on ur car.

Here's the thing and natural kind of hit on it but putting 20s on will not shorten up the wheel gap. In order to do that you need to put lowering spring on but I also agree that 20s on a stock v6 mustang don't look too hot jmo though.

There's hardly a noticeable power difference at all. I'm on stock suspension and I don't think the gap is bad at all either, lowering isn't a necessity.

I have the GT front bumper and rockers though which make the rims look a lot better than the stock v6 body parts IMO

whenever 20's are mentioned on our cars everyone brings up performance. is there any evidence on how much power is loss? other then the fact that someone saying "you can feel can the difference".

Wheel selection has allot to do with it. I was JUST about to say that 20's generally look ghetto-fabulous...but Amort's car looks quite good.

18's are the best of both worlds WRT a balance of looks and performance...but you will still to drop an inch to lose the gap. I personally dont mind it...has a muscle car look. Afterall, this isnt a Civic.

theres no statistical evidence i know of regarding the loss of power. however power was a question of concern posed by the OP. and as u stated theres no evidence so in order to answer the OP the only thing i could say is yes you CAN feel a difference of some sort...

there was a member in the 3.8 section who picked up 27 rwhp on a dyno going from 20s back to stock 15s (i think his name was SAI or something?) they weigh alot more, and they usually are slightly taller but that depends on tire sizes, notice i said usually.

only things id recomemnd are a drop, cause it will look like an explorer, and upgrading the crappy *** stock 7.5 with either detroit/eaton or upgrading to an 8.8

Yes there is. Get exact wheels and I can calculate the difference...it is not too hard to reproduce.

Here is an easy task if you have a set of golf clubs at home. Pick up a wedge and a driver (a modern driver, not something from the 80's).

Grab them at the grip and begin a full cycle in 360 degrees.

Now repeat with the wedge.

Lets pretend they are the same weight (they will be close FWIW). Feel the difference? That is wasted torque as the overall wheel diameter is the same between 20's with 35's and 16's with 65's. Add in an extra 7-12 pounds per wheel and the problem gets even worse.
