i think it looks good, but why not run 20s or 19s all around? seems like the rear is sitting a little to high, it wasn't to be lowered on the rear it seems.

cuz i wanted to maybe run the GT500 wheels on my 5.0 when i get it, but I'm not sure if i want to get 19s or 20s all around, just not sure if i like the 19s and 20s combo.


i would lower the rear a bit anyways, so it might look good with 19s all around, but if i do 20s all around the front wheels might look to big?

 

2 reasons why rears are larger, usually wider too.

1. so you have more traction as a RWD vehicle
2. with so much HP when you accelerate the front will lift up, so u can still have view out the front

 

Always wondered that as well. And it is the reason I'm not pulling the trigger on a local set of SVTPP wheels

 

I'm sure the engineers found while fine tuning the suspension that the combo gave the best handling and traction.

Maybe they liked the sidewall compliance characteristics of the 19's better on the front over a shorter, stiffer sidewall on a like diameter 20.

 

I know that a 20 on the rear can clear more suspension pieces and be wider than a 19.

Sometimes I think that a wide 19 with tire still might hit the shock dust boot but a 20 buys a few extra mm as the larger circumference puts it further up and away.

I think. But that might not explain why Ford did it because they still haven't put a really wide tire on there yet.

 

This.

 

If you're not buying them, then hook a brutha up, man! I dream of those things!!

 

It looks better IMO

 

^^^^i too don't understand why they haven't gone with wider meats for the Shelby's, especially more importantly for the coming 2013.

 

The head of SVT explained that already.

 

Umm, uhhh... Jamal Hameedi uhh kinda talks about it in uhh, this clip.



He answers the question indirectly- saying the car can't turn with bigger fronts. I think they just got lazy... He says to look at competitors in this HP/track class- I did, the cars have big rears and compatible fronts...

IDK what he's talking about. No biggie tho.

 

"I think they just got lazy" I think you nailed it.

 

He is saying that the steering precision and turn in are affected by the front tire size and overall handling of the car affected by huge rears and smaller fronts. A lot of the current cars considered to be the top handling cars have comparable tire sizes

2012 Porsche 911 had 235 fronts/265 rears

Svt is trying to shed the gt500's reputation as a straighline/drag car and try and make it a better handling well rounded sports car (which is tough). To the OP I am not sure what the 19 front and 20 rear does. I just added the svtpp wheels to my boss. Will let you know if it feels different.

 

Respectively, you can't compare mid mount/rear engine to a front.

Front Engine, High HP, seen on track and drag, and noted for handling:

Viper ACR
Fronts: 295/30/18
Rears: 345/30/19

SL AMG Black Series
Fronts: 265/35/19
Rears: 325/30/20

ZR1
Fronts: 285/30/19
Rears: 335/25/20

ZL1
Fronts: 285/35/20
Rears: 305/35/2-

All I'm saying is they increase HP solid, but stick with a tire that barely contained 550hp. And opt out for launch control rather than "engineer" new capabilities for tire ratios.

 

Respectively 1 to 2 more inches of tread isn't going to do jack squat.

 

Not street tires. It's gonna take some DRs to lock down that power just for street use.

 

I agree those cars are way different class of cars, was just saying they are considered world class handling and that is what he was saying in the video. Maybe they need to come with a nt01 tire lol

 

alls I can tell you is those two ladies at the bigining of the vid are pretty Hot
the taller rear tires can handle a little more tq before breaking loose

Now, I have to go look. I'll be right back...
