Do everything in your power to "test sit" any seat you are thinking about buying. It will make a huge difference in your final decision.
Descriptions and personal commentaries are great, but it just cant replace a first hand trial. I know it can be hard to find the seats you want and be able to sit in them, but it can be done. Car shows are a great place.... just be polite and curteous and most guys will let you sit in their car for a minute... just be clean and dont start fondling the rest of the car
I have the Corbeau CR1's in the wide version.... I'm 6'3" 210 lbs and they fit perfect for me..... snug and comfortable but not too tight or restrictive for a street car.
