They look way better in person! These were for a dual spare setup and they actually look great and would buy a full set if I was in the market for a full set. The price was great as well.

Great looking wheel!

Put these on my 2013 Lincoln MKZ in machined grey. Got tired of the factory 19’s bending every time we hit a pothole. Went with an 18 on these and saved 7 pounds per wheel. They look great and the ride is better too.

I had got some rims like these ones before. So I decided to buy more. They’re very awesome looking the color. The depth of the rim is awesome. Looks great on my car.

Great to do business with

Great company to work with in purchasing your new wheels and related products. Initially, I was going to give only 4 stars due to the fact that the wheels I really wanted were actually on backorder despite being advertised as “in stock” on their website and the need to buy the last full set for the advertised price (which further implied the wheels were available). Initially blamed wheel manufacturer for not updating their supply which I believe is true but it’s also TFSWheels’ responsibility to maintain their own site. Nonetheless, TFSWheels was quick to respond and offered to refund my purchase. I decided to pick another wheel that they did have in stock. Throughout the exchange, TFSWheels (Jeremiah) was very responsive to all my questions or concerns. They even made sure if I knew my wheels would fit since I have an older Land Cruiser. Once selected, they stood by their pricing for the new selection and service was outstanding. Wheels arrived in great condition and now I am even happier after seeing my new selection. So 5 stars is the right rating and I would buy again from them!

Amazing Wheels

Love the style. Looks stock and classy, not too much. Clients love the exposed red brake calipers and clean look when pulling up.

Excellent service! Recommend.

Excellent service provided by Jeremiah. Great communication, went the extra mile trying to find a perfect fit for my car. The wheels were beautiful, great quality, fast shipping, but unfortunately not a fit for my vehicle. Would recommend TFS to anyone who needs new wheels!

I was very happy with purchase. Did have a bump with lugs. Jerrimah and worked through it. Just verify some Lexus use lug bolts instead of lug nuts. Very happy with end results

Delivered as promised for the most part.

Had a little back and forth on how many were actually available, but communication got us through that. Product is spot on what was advertised though. One piece of advice would be to look carefully at the color of the trim on your car if you are getting gunmetal. I love the gunmetal finish, but the silver (shiny’er) one would have been an even better match. No complaints on our S90L though.
