[Roadsters] test drive and feel for scorch

[O'Farrell, Fergus P (AS)]

No, not just lucky, sorry, didn't mean to raise worries.

The other method is a heat shield, which basically is an interim surface which heats up (and has airflow behind it) and lets the heat disperse the heat before it radiates into something neighboring. 

If it is only touching the body in one spot, that is probably fine, maybe do an experiment and whip out the carpet in that area and take a typical drive (including an extended sitting period) and see how hot the floorboard gets to your hand.  Use the backside of your fingers, as palms are pretty tough.  If fingers can stand up to it, it is fine.

If it starts feeling scorching, then bending that heat shield so there is even the smallest gap is the solution.

Subject: EXT :RE: [Roadsters] body-to-muffler gapping, 1" required

my muffler has a heat shield on it and that is basically right up 
against the body. I have not noticed any issues and have sat in Chicago 
interstate traffic in this Roadster in teh middle of summer for hours 
barely moving.

Am I not having melting issues becuase of the heat shield? Seems awful 
close (touching the body in one spot) to me. Am I just lucky?
