Best racing seats for me?

I am of the opinion that ANY item that improves your comfort and/or safety is worth the investment. I have a '72 Scamp with a bench. No support whatsoever. Like sitting on a park bench. Bucket seats were not available in '71 so I looked for a '71 bucket or one from a Duster. About $1k for 2 seats to restore. Aftermarket buckets make sense (and dollars). I would go one step further and install a 6 point roll bar. I was crew on a Dodge bracket car when the driveline let go at 1000 ft mark . Oil got on the slicks and the car rolled 4x and caught fire. The car was destroyed but the roll bar SAVED HIS LIFE. This was a high 11 second car. I have one in my 13 sec Scamp
