Finally done with my Alcoa project!! 10's up front, 12's out back..............
- Thread starter Robert M
- Start date
Reality check - It is all part of getting better traction, when there is real horsepower up front.
The choice is...........adding wider/heavier rubber and associated wider/heavier rim/wheel in an "attempt" to hook up better OR worry about the extra weight while the guy who is hooking up drives away from you.
Believe me, I know about the added weight, I lifted those tire/wheel assy's. up onto the wheel studs, but I also remember how much of a roller skate this car was with the smaller/lighter tires on the rear.
I do have a realistic weight comparision for the Michelin Pilot Sport PS2's that I have pictured above which I sold when I decided to go with the Dunlops.
The 275/35/20 PS2 weighs 27.70 lbs.
The 335/30/20 PS2 weighs 34.70 lbs.
Both weights listed above are tires only on a FedEx scale.

This was 2 sets of wheels (f&r)? Was is Weldcraft that also performed the services for smoothing the welds.
Looks great!
^^^This was one pair of wheels, rear's widened to 12" and smoothing the welds.
The fronts are the original Super Snake 10" rear wheels, no widening needed.
Thanks!

Your SS is now my new screen saver. Beautiful ride and well done. Really can't tell if anything has been modified from the original specs. Good job!
Cool!!:thumbsup: Thanks!!:thumbsup:
That was my goal, keeping it looking like an original Super Snake while also benefiting from more traction for the rear in a straight line, and also more front grip for the turns.

Beautifully done,and sweet ride man!
I apologize if I missed it somewhere, but which Alcoa did you have widened to 12". I'm curious because the offset is different between the 9" and 10" wheel and could be the difference between getting the rubbing I've seen on other threads.
Beautiful ride! Thanks for the posts.

Actually I widened a pair of 9's to 12" and then moved my original 10" from the rear, to the front. I had the opportunity to buy 4 spare Super Snake logo'ed wheels for my Super Snake and use them for the widening project, BUT all 4 were 9" front wheels. I knew this was not an issue since I had already done some homework and found that the measurement from the brake mounting surface to the outside was the same on the 9" and 10" Alcoa's and the 1" difference was to the inside only. This mean't that either a 9 or a 10 could be widened to my desired 12" for the rear.
After I installed the 12" on the rear did I realize through test fitting that there is enough room to the inside for a 10" fit on the front.
So in the end, I ended up with 2 9's widened to 12" for the rear, and moved my original 10" rear Super Snake wheels to the front, for now.
My near future plan is to widen my second pair of "spare" 9's to 10" (another $712), put them on the front, and put my perfect/mint original Super Snake wheels, 9's and 10's with Pirelli P Zero tires away in climate controlled storage.
Widening is now the easy part (except the $$$), the key was to find out what tire and Alcoa wheel combo's fit the best.
All I can say is that this tire/wheel combo works on my 2008 GT500 Super Snake.

So you didn't notice any difference with the 9" --> 12" on the rears with the different offset as compared to the 10"? I'll finally be back in about two months and will be sending off my Alcoas to be widened and was going to send out the 9" set.

Thanks for the update!
I started crunching the numbers after I had asked the question and realized like you pointed out the distance to the outside of the wheel was the same on both the 9 & 10 so it doesn't effect the result of widening the Alcoas to the inside. It looks like you end up with an offset of around 62.1mm widened out to 12" on either wheel.
I've got a 2010 that I desperately need more tire under so I've been trying to develop some working measurements. I like the Alcoas, but haven't decided to go that way yet.

With the Alcoa's the distance from the brake rotor mounting surface outward (to the face of the wheel) is the same on both 9's and 10's.
From the brake rotor surface toward the inside (back of the wheel), there is 1" difference, 9's vs. 10's.

I know this is an old thread...
Great info and thank you for posting.
I think for shipping savings I will just have them shipped from Shelby to Vaugn

I weighed the Alcoas VS the Stock GT500 rims. The Stock GT500 Rims and tires are HEAVIER than the Alcoas with tires.
op:Not sure what the difference would be after widening them.... :rolling:

Adding to your reply above..........
Yes, it would be like saying to the owner of the GT500 below........."I'll bet those tires and wheels are heavy".
**Reality check** - The oem tire/wheel set-up is marginal for even the original hp output, adding more power makes it worse. To even have a thought of getting a grip when real hp is added requires more rubber. More/wider rubber requires wider wheels, wider wheels and tires add weight. It is just a fact of life........
The option, keep the lightweight narrower wheels and tires and cry about no traction............

So...how'd they do in terms of traction? I never saw any comments about that
The 325's push the car straight forward, not the dance and slide around like it did with the original's. It will still spin them, but it takes a little more effort and the car does not get loose as quick as it previously did. If I were to lower the tire pressure it would probably help a little more, but I keep them in the TPMS range.

Looks awesome man.
