Seat?

[timo944]

What's the thinking about the strength of aluminum vs. fiberglass? I hear (from vendors) that Aluminum is unsafe, but then I think about it and Aluminum will give (ie bend) where fiberglass will crack. Also all of the stock car guys including, I believe NASCAR, use aluminum. I think the vendors like to up-sell to the fiberglass option.

FWIW I've used a Kirkey for years and really trust it but want to upgrade to a seat with head support.

I have nothing against aluminum seats, my 1st race car had a Kirkey but it was not confortable, I switched to Fibergalss even before I started selling them, my friend David Boles in Melbourne FL always used aluminum seates until he tried one of my fiberglass and now he only uses a fiberglass seat.
If you don't want to spend the money look at the Sparco Sprint 5 or MOMO Tframe ( MOMO is out of seats until 2010), it is a tubular seat FIA approved and very confortable, I had the Sprint 5 last year in my ITC car and loved it, great for endurance racing.
As for safety, I think I would rather have an approved FIA seat over a non approved one.

Actually composite seats are making a break through in NASCAR:

FIA composite seats are tested to standard, albeit not the best one ever. Not sure if the aluminum seat manufacturer's test their seat designs. I would think they would, but I haven't seen it advertised anywhere.
