Absolutely stoked with the products!
Ordered the D shape race wheel in suede! Was on back order but when the wheel finally arrived the quality was so worth the wait. Don't waste your money on a cheap autobarn or supercheap steering wheel. you'll be disappointed you didn't buy one from these guys! Cant recommend enough❤️
