The Boss is not a base Model... It is a Boss 302. categorized even by Ford...On its own.

my SRT4 is not a base model... Also categorized by Dodge ...on its own.

The cars are stock base models ...on their own... equipped as per the teams that speced them for their function. therefore not plus sized... They are stock.

Your car is basically stock for its model year. therefore... Your current custom wheels/tires should be considered plus sized for the stock application of your model vehicle. really simple.

If you pattern your Vehicle as I did... To be a sleeper with the same power Mods and suspension as a Roush then you equip the vehicle accordingly to be on par or better than the Roush. again really simple. They did the homework and already provided a package that is fitted for its intended purpose. for what would be considered their base model platform.

A 5.0 out the door is 100 HP more than yours. therefore a CS or Brembo or Premium package is OEM equipped. With 19's.... The appropriate pocket for that vehicle...since it is putting down 1HP per every 8lbs of car. again. Really simple.

power mods would increase the power to weight ratio and thus put it in a category closer to an SVT Cobra... Again another size fitment for that purpose.

if you need to further understand the concept... You'll need to upgrade your Mustang to the same power range or just get a 5.0 coyote with a better rear axle than the base 3:31.

again really simple concept.


Know the application then make the proper fitment for that purpose.

If you go by the homework you've done you can also come away with this ... the pocket they chose was plus1 and plus 2 over stock as the sweet spot. If this is applied to the current s197 mustangs from 2011 and up then that plus1 and plus 2 sweet spot is a 19 to 20 inch wheel/tire combo. Which again makes sense given the current factory power to weight ratios.

Or in your case you've basically remained stock for your model year on the power side. in which case for your stock application.... You should have stayed with 17's. But, since you lowered it... It can likely accommodate 18's and more power, however once you match that power/ torque and handling....you're no longer stock are you... No longer plus sizing over a stock configuration but instead "appropriately" sizing...aka "right-sizing" for your specific application. Again a really simple concept...get to work on that....

all in good fun.

I'm speculating here but the homework the big names have done is most likely plus sizing. I imagine they might stray from it to meet the needs of what they've done to the car. Can't really go wrong, the tuners pretty much know what they're doing.

Then I changed it to a 2014 GT. The results showed the stock size of 235/50/18 and now I could select View Optional/Plus Sizes. There are many plus sizes to choose from, including the 265/40/19 that are on the Shelby, don't know why they didn't include the rear tires from the Shelby. I'd venture to say that if you plug any of these plus sizes into a tire size calculator, they'll match the stock diameter or be close to it.

Looks to me like they went with a plus one on the front, a plus two on the rear on the Shelby.

After upgrading the suspension, I can't imagine going bigger, the ride got a lot firmer with the Roush springs and D-specs but at least I can tune it for a softer ride.

I imagine you'll dismiss what I've said but people have been using the plus size formula for years. How you choose or whatever size you choose to roll on, it's your choice and you're the one who has to live with it.

Thanks.


BTW...forged wheels would be preferred(lighter/stronger) if you can afford them. They are expensive though. If money is no object then you go with Billet formed wheels(very light/strong).

And yes as a bang for your buck the Sumi's definitely fit the bill, down in Fla..

Again..sweet ride.. not overdone, simply stated very classy and the only decal being the fade is just elegant without having to overstate the existing clean lines on the body of the car. Those Stangs with all the decals and marking.... seems very immature. Like someone screaming for their youth and hot wheels cars collection.

If I didn't have to pay for my Son's karate classes, inline hockey equipment/league fees and my Daughter's dance/swim league stuff, I could have a really nice set of wheels! LOL

Thanks for the props on my Sixxer! My goal is to make her look clean, classy and unique. I was a bit nervous adding the Saleen stripe decal and people thinking I was a poser. I just wanted some accent color to match the Cobra wheels, which I feel goes well together. I did not include any Saleen wording, so my Mustang is not being portrayed as a Saleen, which would be a poser move.

Cheers.
