Alcoa 20x10 up front for a 2007 GT500


Recommended Posts

Wondering if anyone can assist?  I am looking at buying a set of Alcoa 20x10 that a fellow I know has for sale.  I am not sure if they will fit the front of a 2007 Shelby without issues.  Car has not been lowered or anything.

I have seen on other forums that they should fit fine, without a spacer, and if so, what would be a good tire size for the front?

Yes they fit Great, I have had them on my Super Snake for about 8 or maybe 9 years with no spacers or tire contact with 275/35's.

If the search is still available for older posts here on Team Shelby, in the 2007-2012 Super Snake forum I was the first person to experiment with 10's on the front when everyone was "swearing" there was no way they would fit!

At that time many years ago I had purchased a second set of Super Snake Alcoa's for my 2008 so I was able to do measurements w/o tires in the way. Once I found that the measurement from the disc brake mounting surface to the outer face/edge of the Alcoa was the same on both 9" and 10", I knew it would work fine to use 10" on the front from an appearance standpoint, and once I installed a 275/35 on that 10" Alcoa and then mounted it on the front of my Super Snake and turned the wheels from lock to lock with no tire contact issues..........THEN I knew the nay-sayers did not know what they were talking about.

^^^From that point I had the spare pair of 9's widened for the rear.

I found my original pictures after I had measured the 9" and 10" bare Alcoa's w/o tires and then decided to "test fit" my original rear 10" Super Snake Alcoa's on the front, with the original 275/35 Pirelli P-Zero's that Shelby had installed when my car went through Las Vegas.

It looked perfect on the initial "test" install.......

Turned lock to lock without contact.......

.......and rolled freely with no contact against my Shelby installed Eibach Pro Street-S coil over struts.......

^^^Those pictures were from approx. early 2010.  I have had 10" Alcoa's on the front of my 2008 Super Snake since that time, and what a Great upgrade to the handling when I press my car into a turn!! The increase overall diameter along with the slightly wider width provided a much more sure footed feel on the front of my heavy nosed 2008 Super Snake.
