Ok I see we are thinking the same way, but wouldn't it make a better improvement with how light the ALCOA's are compared to stock or no? That's my problem I love the look of the 20'S BUT was waiting to see if we would could buy the 18's on the production KR to keep the wheel & tire as light as possible. Someone chime in with the 20's here how's the weight?Rotation weight if that is an issue for you. The bigger the rim, the bigger the tire, and more weight. Takes more HP to turn more weight. Splitting hairs I know but if your anal about the most performance than 20's would be an issue. I wanted the 18in razors, I called Shelby support and they said they would not work. I ask than how does my factory 18's clear the brakes and he said that rim was designed special for our cars and that standard 18in rims would not clear. I hate the words CAN'T AND NO. the most. Not sure if there is any 18inch rims that look good and will fit out cars ? My father raced a GTO back in the day and I drag raced motorcycles for a while so yes I am anal about performance...it is a curse that I can't shake. But the 20's look great don't get me wrong just I want 18's. Anyone have any ideas please post up.
Have the 20" Chrome Razors on mine. They are SWEET!!!!!! Get a lot of compliments on them...Just saw pics of a set of Razors someone had widened to 10.5. They say there are no clearence problems as of yet, but are still installing stuff.
I'll see if I can find the post on another site.
I've been waiting on silver 20" Razors since NOVEMEBER. Since I'm posting here, I'll say, SAI has 80 sets that they are sitting on and not sending to the parts side of the house. When I first ordered, SPP said that their shipment had been mis-shipped to SAI and it'd be a couple of weeks. That was Nov. When I called back in Jan. they said the wheels were never theirs, they were SAIs.
So I'm waiting on a new shipment to clear customs before I can buy mine from Discount Tire. I do not wish to comment on why they wouldn't part with one set after I had been waiting since November. And I never got a straight answer.
Discount Tire has done what they can, but American Racing has said they discontinued normal production for the GT500 and will only make them in lots of 60.
And my second choice, the CS67 won't even fit a GT500. What a great business decision. Make a Shelby wheel and it not fit a Shelby.
But I do love my car.
EDIT: Here's the thread on another site for the 10.5 widened Razor
10.5 Razor Wheel
I think for the most part, the more sidewall the better the ride. When you go to 20" wheels and mount tires to keep the overall diameter the same you sacrifice sidewall.I just discovered this thread after doing a search for 20" wheels. I just put 20" wheels on my car yesterday, and I have already noticed significant difference in the ride. I am not thinking it is for the better. The car appears to accelerate much slower, and the rpm's rev up extremely quickly.
I know that the 40th Anniversary and Super Snake packages lower the suspension. Does this alter the way the car drives, or is this solely for handling? I knew things would change a bit when I purchased the wheels, but I wasn't expecting anything this drastic.
