bpracer said:Finally got to the track today (MSR-Cresson) with the larger rear sway bar to match the R springs and it does the work better as one would expect!
It was chilly in the morning and I wasn't trying to push the car too much, I really went to coach a friend that just picked up 2001 911 Turbo... But then there was another GT-350 there and it left me while my tires slid around.
The last session I ran I finally got the air pressure low enough to get the tires to stick. Overall the car felt neutral, with some lower speed understeer (but likely I was getting in on the gas to soon). The car had more oversteer on fast turns until the tires got hot. At that point the car seemed more neutral overall.
I must have been spinning the left rear more than I thought because it was 2psi higher than the rest when I finished.
My tire pressure gauge shows about one psi less on average than TPMS readings.
My next tire pressure starting point for this track will likely be:
LF 27.5 RF 27
LR 28 RR 26.5
I guess I need to take some tire temps.
The other things that was absent this time was some shuddering from the front end when pushed really hard. My only other modification was a Steeda G-Track brace. It seems to help tram-lining on the highway as somebody in the M6G forum stated that it "cured" that problem for them. I think it is slightly better, but certainly far from cured. It's pretty cheap, looks like it should do something to triangulate the front sub-frame and it can't hurt other than adding a little weight.
I'm getting more comfortable with the car but a little voice in the back of my head keeps telling me I have 50+ payments remaining.
Three questions: What was the ambient temperature? Which tires? What was the hot tire pressure?
