My main plan is to extract a few seconds out of my lap times with the "driver mod" while leaving the car alone. I learned in my last track day of 2016 that the car has more in it, without any further modificatoins.
About the titanium brake shims -- my Brembo kit came with tapered shims. Meaning they look similar to the ones you guys have, but the lower edge is cut on an angle. I guess they are supposed to provide the heat shield and also compensate for pad wear or something. I have noticed that my pads wear at an angle but haven't put the whole picture together on how that tapered cut works with or against that uneven wear.
Have any of you seen that; do you know why they are cut that way? (I think I have some pictures somewhere . . . )

Good plan! Focus on the line. It's always nice to see what an experienced driver does different in your own car! Line mod (driver mod) is always the best way to shave lap time!
Yes, mine are the same. It's like the shim at the trailing edge of the piston is cut at ~30 deg angle. I'm still not sure why. Could be noise. Or it might be due to contact force on the trailing edge. You'll notice in calipers with 6 pistons the pistons are different size to count for torsional forces the pistons and rotor enact on the pads.
So covering it all makes sense to lessen the heat transfer...
But metals are great heat conductors, so why does this work again??
I would expect carbon fiber or some sort of polymer but straight up titanium??
But you know what? If you guys say it works I'll try it too

Somehow I missed this earlier!

Mostly I think I need to work on my nerve, to go faster than I think is possible and still keep the car on the track. Or somehow work on my ability to save it if things get squirly at high speed. When the speeds get up around 100 MPH I lose my nerve because I am not confident that I can save it if I get in trouble so I don't push the envelope. He was just plain going faster than me in some sections of the track; staying in the gas when I was lifting a little, in very fast sections of the track with minor curves and big rock walls . . .
About the shims as heat shields -- doesn't really make sense to me either. Maybe the titanium distributes the heat more evenly to prevent major hot spots. Metals are generally good conductors like you say, but I think titanium has relatively low thermal conductivity so maybe that has something to do with it. Or maybe a layer of anything between the pad and the pistons reduces the heat transfer into the pistons enough to make a difference.

Friday night project; I'll finish oil cooler install tomorrow :-)

^ Looking good! I assume you have an oil temp gauge in or going in as well?
Waiting for taxes to come back, then the rest of my goodies will be ordered! The additional track car set me back a bit too though... now I have 2 track toys and the Tahoe.

Installed new race pads with ti plates & brake flush over the weekend. TI plates installed without a hitch :-)

Just installed AutoBlip, let's just say my back and ribs are glad it's over :-) quick drive: won't engage until you press clutch all the way, rpm blip adjustment is easy. Can't say for sure until I'm out on track (COTA) but from my quick drive downshifts were seamless and in the powerband (no shock if that makes sense). Happy with purchase :-)

Passed tech inspection, car loaded, and packed, next stop COTA :-)

Nice!!! Please post pics and videos! Do you have Harry's or similar to get data overlay? If not, I'd recommend it! COTA will see some impressive numbers I think

Thx guys. We made it to Austin, passed COTA on the way to my friends house. I ready for trackday this Friday :-)

Sadly I was still dealing with over heating issues

Hey SGwick, nice lap! What a great track, looks awesome. And you got near 140 on the back straight.
Sorry to hear you're still having over temp issues. That blows after all the work you did over the winter.
Do do you have any temp data? I've been thinking about this also. The CAI and tune raise your redline by 400 rmp. Do you think that is a contributing factor? More rpm more friction more heat? I will be installing mine soon and I'm wondering if I will run into this issue as well. More fuel, more spark advance more power more rpm all adds up to more heat.
