Orthojoe's track build journal
#212
Great driving and really good camera work! Just very good sensation for how fast you're driving! There is a thread about Chris Harris in this gt3 forum! Amazingly poor camera work compared to yours! I would like to see more of these camera angles and still keep a bit of his drifting! Just gets tiering to watch Harris drift around the same corner over and over again!

Orthojoe - really appreciate you taking the time and effort to document all this; I'm finding the thread very enjoyable and a good source of real world track-based information. Keep it coming ...

If you don't boil it at Laguna, then maybe OEM fluid with just a solid replacement schedule will work out just dandy.

On my friend's Audi, the dealer refused to warranty a faulty ABS valve unit because he was running aftermarket fluid. Oh, and on *my* Audi they refused to warranty the caliper piston boots due to me running aftermarket brake pads. So I guess I'm a bit paranoid now...

Yeah, they are stout with plenty of ducting. I wouldn't bother changing the fluid until it's time, and then switch to your preferred fluid

To me, the Cantrell bar looks more stout. Also, supposedly the bar is designed and made so it will actually line up to the mounting points without having to winch and pull. I'm still waiting to take delivery of it and will report back how the install goes

The Cantrell bar has cross-bracing in the vertical plane, which is the plane you want to strengthen in case the roll bar is asked to do its job in the event of a roll. The diagonal plane going back is there primarily to keep the vertical plane oriented vertically; it doesn't need to be especially strong, but no real downside to having cross-bracing in that plane, other than added weight.
The GMG bar has NO cross-bracing in the vertical plane. To my structural engineer's eye, that's a fail.
Compare with the configuration of Porsche's clubsport roll bar:
