Billy, let me understand your perspective. The NSX's OEM suspension was developed by Senna's input as well as extensive testing afterward by Patrick Johnston. Yes, that was some 20 years ago, and yes technology has advanced where "drivers" can improve on pretty much all aspects of any model year NSX.
Having said this, is your position that a driver like Dave with limited seat time, and quite a high level of being risk averse, is in a position to have reached the limits of the OEM set up in such a short time so much so to do all the significant suspension and alignment changes that you are recommending - even with a CTSC?
Dave's car is NOT a track car and he tracks on street tires hence a racing suspension, IMHO, is not an appropriate advice - perhaps the 91 alignment is if he is willing to accept tire wear. The OEM brakes are fine but we have already talked about any tracker needs better pads and I believe Dave has shopped for those before. We agree regarding baffled pan - but again let's not oversell this in its critical importance with street tires or tracks that are pretty flat. Some of us locals have tracked for 8 years and at least 6-10 tracks per year with the OEM pan with no issues - but yes there is a statistical probability that it might happen.
Dave, regarding tire pressure with your current OEM set up, the OEM tires like hot at the track no more than 33/40 psi. Try to to see how that works with your aftermarket tires and adjust by no more than 2 psi at a time (don't putz around during cool down lap if you are checking tire pressure - also check tire temperatures across if you have the tool). The tire pressures do make a huge difference in feeling planted vs. loose and greasy if they are too hot.
I still think for now, the best value for Dave is seat time (professional school is great if it is in the budget), toe link/rear bushings and sway bars. Baffle too :wink:
