Lol! Just saw this:

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 ...

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...

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

Thank you! As you can probably tell, I enjoy putting together these videos. I also find them very helpful to review and improve my driving.

Thanks, man! I'm glad others are enjoying this thread as much as me!

Yeah, I don't see a reason to change the fluid at this point. I can easily smoke the brakes on lesser powered cars with smaller brakes. The standard S brakes on a cayman or boxster I can smoke (it only took 2 laps at Laguna to smoke the cayman GTS brakes). However, despite the high speeds, the GT3 brakes never smoked. BTW, I would consider caliper piston boots a consumable item. If you're running hard on track, they will fall apart.

Sounds like brake cooling in this GT3 is good. I guess I won't change the fluid yet, but I plan to go with SRF when I do change it.

orthojoe

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

You stated you are getting the Cantrell bar. Was there a reason you chose them over GMG? I am getting ready to order one, but was not sure. Is it material/welds/fitment/finish?

Thanks!

orthojoe

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

Tosilog

Joe, when do you plan to change/bleed your brake fluid? How many track day interval?

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:

Thanks, I will call Cantrell.

orthojoe

Good question. Haven't decided yet. If the fluid never boils and the pedal feel stays solid, probably once a season. I hate doing brake bleeds....

Is there any other reason other than crash protection / safety for adding a roll cage? Required for racing? Txs.

orthojoe

1) protection and safety
2) the ability to run a harness

not required for HPDE, but recommended for a car as fast as this
