The roll bar in my 911 prohibits for the most part, the recline feature of my DAD seats, so I may ditch them entirely and save some weight in the process. I've been looking at Kirkeys for some time, and may pull the trigger soon. For those who have Kirkey seats, what type do you use? What height are they (or is "it" for those 911s with one seat)? 15-inches? Taller? And how are they for daily driving? Kirkey doesn't recommend them for daily driving, but I want opinions from those who have them in their 911s. I spoke to a Miata spec guy who says they're very comfortable - but that's on the track. Any help is appreciated. Thanks.
