How much do Sport Seats weigh?

[bmuser]

Hey guys, i gots me a '91 318is with the sport seats. I like them, but, im trying to throw away as much stuff as i can, but still have it bareble for a DD, to save weight. I took out the turnk lining, working on getting some Team Dynamic rims, 15" wich weigh a little over 13 lbs each, lighter tires such as Falkens (dont remmeber the model) that weight 20lbs.

Now im thinking of a sport seat. I like Corbeau's, not too expensive, and the sport ones weight 27lbs.

How much do my sport seats weight?
Whats the best sport seat for the money?
Whats the lightest?

thanks
