Good on you. Everyone should eat right. Always amazes me what people manage to shove down their gullets, just no thought at all. Balance is the key. It can be hard to do sometimes, especially at the track or on the road where all they got is burgers and soda. Sometimes you have to plan ahead a little.

Seats - in my car, I used seats from an '80s Jeep Scrambler/Wrangler. I posted them here while back. They are very similar to A100 seats and look like they belong in a muscle car. Same kind of plain upholstery, fixed back and very light. My seats with S/S seat brackets weigh 22 lbs. each. which were slightly less than the A100s. Pretty comfortable actually and a little better support than a low back bucket.
