We are supposed to adjust for size only with the pedals, they move quite a bit. If you are longer in the body, the seat can becomes a factor.
The car comes with a fiberglass seat or you can get a "custom" Butler aluminum seat. The Butler gives a little more flexibility in seating position, but takes up more space.
I'm 6'6", 220, with long legs, my personal car has a fiberglass seat opened up a little in the hips so I can spread my knees out a little. I have driven a few cars with Butlers, but have yet to find one where I am not making at least some small concession to make up for improper fit.
Best bet, try sitting in different different cars, most people are cool about it.
At 200, you may need either heavy bodywork or a couple lbs of ballast to make minimum weight.
Hard to go wrong with Scott Rettich, he is kind of good at it.

Question for you, good sir:
I'm about to take the plunge, but have one safety concern. I'm 6'4, 260. The length is mostly leg, the weight is mostly torso. (I'm an odd looking human.) I've been in two SRFs now, both with stock seats and the pedals all the way at the nose. Fit was generally fine, BUT no matter how I shifted my legs around, the bottom of the dashboard rested flush against my upper thighs.
I know that, per the rulebook, I can't shove the whole thing upwards, can't bend the last couple inches back to give me some clearance, etc. I'm 98% sure I could glue on a half inch or so of dense foam to give me a little protection. But as a guy whose been through a few rodeos and CERTAINLY has it worse than me:
1) what do you do to protect your thighs from damage upon driver error?
2) it seems far more dangerous than, say, resting a knee against a padded piece of cage, because when energy starts being transferred, there's plenty of places for the bent leg to go. No matter what the nature of impact, energy is going to be traveling down through the top of my thighs, and the only damage I want to be doing to my femoral arteries is at Whataburger on the way back from the track. Assumming you've copped a reasonable hit at some point, how did your thighs hold up?
3) also assuming that, because of your frame, you're wedged in at one or two other unusual places too - what do you do for comfort on sessions that run more than 15-20 minutes? Foam? Subconsciously moving things around / flexing / etc. on straightaways?
Basically, if you could be my Giant Obi Wan and teach a big man how to make these cars fit, I would really appreciate it. (With an emphasis on the thigh vs. dashboard issue that is giving me nightmares.)
