Al! Didn't know you're on this board! Guys, don't let this guy fool you with his 924S: at last week's DE at Lime Rock, he OWNED several high HP cars, including an air cooled 911 Turbo, and a pair of 996TT's! It was fun to watch you drive!
See ya tomorrow at Pocono! Sure hope it doesn't rain ALL DAY! How's the 944 project?

Re: the JGRIFF installation. On my 944, the center bracing was bolt-in, yours looks welded in, also the roll bar looks like it installs closer to the front seats than mine did. It also had a diagonal brace. Those look like factory sport seats. There is a problem with the factory seats as the headrest wants to spread the shoulder straps off your shoulders. I got a sternum strap that connects the straps (at the sternum, duh!) to cure that. I have now on order some aftermarket seats (Corbeau) with proper slots to correctly solve the problem. Too bad Porsche couldn't have specified seats to accomodate harnesses, considering the use the cars get. Probably lawyers to blame.

While not ideal, harnesses can be used with stock seats (sans holes).
- If you have a long (~75") shoulder belt, it should be the "H" type. This is for C-pillar or rear seat belt type mountings.
- For B-pillar or rollbar mounting, you would use a short (~48") shoulder belt.
- In addition to each of these, you could add a sternum strap. This will join the two straps together at the chest. There are mixed feeling on the use of a sternum strap, but it is an alternative to the worry of "jiggling" free from around_the_side shoulder harnesses.
Whenever I think about safety, I like to imagine myself barrel-rolling or somersaulting down an embankment with trees at the bottom... maybe throw in a pond-landing or engine-fire to make sure you can egress quickly too. Cars never end up on the roof in a very gentle manner... there's sure to a lot of rockin-n-rollin before you "come to a complete and final stop". I can also understand why so many folks think we may be over-thinking the threat... hell, it took me actually getting shocked before I stopped playing with the outlets... and I was 30 when that happened
Good Luck (and be safe)!

They do in some of the latest "sport" and "racing" models. The 968 CS had these available... as does the current Turbo, GT2, and GT3. I guess you could extract from this that Porsche has a lot of faith in their roll-over protection.
