fuhrius said:a reminder on the disclaimer that I'm just passing along what one guy said...a guy who I think is qualified...but just one guy. And I am coming into this firmly in the camp of of wanting to use an FIA-rated fixed back seat and 6-point harness.
re: HANS - it's an absolute MUST in my book. Apologies if I gave an impression otherwise. I was an early adopter on the HANS (for non-pro's, that is)...recall being heckled at LeMons events for being a wannabee. lol.
re: lap belt mounting - I see that many of you are mounting lap belts to the seat. why not to the existing seat belt mounting bolts?
and an answer to the question on full weld-in versus bolted-to-welded-feet...true you can just cut out the welded bar but that renders the bar useless. I'm thinking that being able to re-use the bar in another s550 is valuable.
Why wouldn't you be able to reweld the hoop and down tubes to new baseplates if you cut them off flush?
