I have been looking at getting some Arizen racing seats for a while now. I just came by some threads on another website about seats made by Ronin and MAD Racing Concepts which from what I can tell are exactly the same as Arizen, but half the price. Arizen offers custom stitching and lumbar support, and custom seat dimensions, but all for extra cost. Just want to know if anyone has heard or sean these seats made by Ronin or MAD Racing Concepts. Thanks
