Plenty of wheels available for much less than $7K. BC Forged, Vossen, Velgen, Signature, Stance….all of them know the GT500 fitment. Of those I’d recommend Signature as @50 Deep does a lot of work to ensure proper clearances and is a huge supporter of M6G. You’ll be hard pressed to find fully forged wheels for less than $4K a set but if you want rotary forged or flow form wheels you can find those for about $400-500 per wheel.
Fitment for the 2020 up GT500 is not easy to find. I looked for awhile and the options are very limited because of the huge brakes. Most 20s don't fit because of the pad height and barrel construction. You can't look at gt or gt350 wheels and expect to find them for the gt500. I just went thru this whole thing looking for some on my car. No f-ing way am I spending 4k plus on wheels when 2 years ago I bought 4 wheels for my gt for $600 shipped lol.
Fresh photo after getting my CFTP springs installed and new wheels mounted. My tires are thirsty but they are getting some Dura Dressing applied this week…
