Thanks for the input. As I mentioned, so far I haven't run into brake fade yet--I'm still not pushing the car quite that hard, but am slowly getting there.
My plan for the ducts is to get the OEM Boss302 (nee California Special foglight) bezels that fit in the lower corners of the bumper. Blowfish Racing has a nice bracket for attaching a 3" hose, then finish off with the Vorshlag disk backing plates. I already have 11' of 3" hi-temp hose.
I do have plans for an oil cooler. I don't run a front plate at all (yes, I know, but only one fix-it over 3 cars & 20 years and this car never got the bumper drilled), so the lower grille is free for this. I am looking at a Setrab HE, a sandwich plate at the oil filter & a thermostat there. I think it's about $1400-ish for all the parts.
I know a tow hook is overdue. Again, plans for that. The Blowfish front which will require minimal cutting on the grille. For the rear I am considering a hidden hitch setup for an eventual tire/tool trailer, then have a tow hook insert for on track.
See? I've been paying attention and reading a ton here. Then doing a lot of thinking, planning & research. I've got a long list of mods all queued up, just need the time & funds to make it all happen. Safety mods are at the top of the list, more go-faster stuff is lower down; the loose nut behind the wheel needs some adjustment & to catch up with the car as it is first.
For the track, I'm not as worried about 5--lots of runoff there. Same goes for 2 (whole oval back straight). Turn 9 is the scary one. The car is already under some lateral load from the 7/8 chicane and there is not much runoff before that wall. This is one of my main focus points for this weekend; I need to change my line there. I think it was Dave who mentioned I need to straighten the line between 8 & 9 (I'm tracking out to the edge & following the curve like seemingly everyone else does). One other place that keeps my thinking is tracking out onto the front straight; I'm not thrilled with the transition to the banking & am not sure of the best way to get there--track out right away & get it done with, or hold the car in a little longer & transition closer to pit in where it's a little smoother.
I will certainly start a new thread after the event. It will likely take most of the week to get to editing the video down--though my overall process is getting better. I've played more with the tools I mentioned earlier in the thread & have a better grasp of them now. There's even single-lap lightweight analysis on the serious-racing.com site. For example, here's the fast lap of the event I posted this thread about:
ACS 5-3-2015 Session 2, lap 2 - 2:02.26
Oh, BTW I skimmed the thread a bit. I messed with that faux-brake-pressure idea and it has potential, but on the data from this last session it's useless. My cheap phone mount is fine for street driving, but is too shaky for the track. So I invested in a RAM Mount holder that so far seems rock-solid. I hope to get cleaner accelerometer data from the phone this time.
Any more aggressive & you'll be completely airborne! That's just a bit more aggressive than I've been running.
