Burning Brakes
Interesting...... You need to get used to your D car. If it's anything at all about momentum, you will not want to use too much brake (IMO).
I just looked at some of my laps on the 3.1 as recorded by TraqMate. On average across several sessions at last October's DE, my entry speed just before a quick "tap" on the brakes (after the crest of the hill and just before turn-in) was 91MPH, after the tap (which was ALWAYS too much) I had pulled back to about 79-81MPH and that was just prior to turn-in. Apex at 79-81 and track-out at 83-84. So even though I thought I had only "tapped" the brakes, I threw the anchor out WAY too much and lost a lot of exit speed.

I have only 15 minutes with fading brakes in the new D car, and that was on the 1.7. So really I have no idea what to expect in that car on the 3.1. All my other experience is in the 993, where I didn't touch the brakes on the 1.7, but had to get on them doing the 3.1 as my approach speed was much higher. I thought most of the other later, faster cars were also braking harder due to the increased approach speed on the 3.1, however I certainly could be wrong.
I am anxious to find out all the differences with my new car compared to what I am used to. I'm sure it will be quite a learning experience. I have my Traqmate hooked up, so hopefully some of that data will speed up the process.
I'll be out of town on Sunday the 5th, or I would try to meet you out there and get some tips!

about downhill ricochet- in regards to braking force and how it varies from car to car...
I've been in a 944Turbo with slicks, S2000 with slicks, 996GT3 with slicks, 993TT with PS2 and yoko048, and followed all sorts of other cars through that turn.
the less HP you have vs tire grip- aka an S2000 with slicks vs a 570hp 993 on street tires- the less you're gonna brake because the tires can actually hold the line you want the car to make. In a car with AWD you're in a much better situation than RWD anytime there's elevation change involved. it just makes it easier- so in a C4 997 with Pzeros, PS2, etc- you're still gonna slide a little bit through the apex- but not as much as a 996GT2 would. This however is the perfect place on the track for a 4 wheel drift in an AWD car, if you're into that kind of thing...
if you've got R-comp tires such as hoosiers or whatever- you barely have to brake, just a little lift over the crest, a small tap to get some weight on the fronts, and bingo you're into the gas down the hill. but if you're on street tires with more than 350 or 400hp- you sure as hell better brake or get your line 97-100% perfect. it's not a place you really want to use too much of the curbing on the inside of the track- especially compared to rattlesnake.
check youtube for MSR 3.1 and see what comes up.

While I can easily feel the difference AWD makes going uphill (T5, T7 and T10 in the ice at Eagles Canyon), I don't particularly notice it going downhill. PSM has kicked in a few times when getting out of shape on a downhill section, but I've just never felt the front pull while on the gas at a downhill apex. Not that I'm ready to try MSR w PSM off, but could PSM be getting in the way of approaching ricochet in the manner you describe? Or maybe I'm just not taking the tires to their limit (I'm on Sport Cups).

Hey guys,
This is going to be my 1st PCA event in the GT3. Should be fun.
Dave,
Do you have time or another instructor to ride with me so that I learn the 911 line. I did a TDE event with the 3 a few months ago. Unfortunately it was a bit wet and I didn't want to take chances with my new baby. So I was barely pushing it.
