Hrant:
Thanks for replying this and previous posts 
The alignment was made after installing the Bilstein/Comptech suspension by Honda in Germany. So the toe/camber should be according to OEM set-up. Everything was made with the 18/19'' combo on the car.
OEM cold tire pressure is 33 psi front and 40 rear. Yesterday I just experimented with less pressure in my rears to see how this affected the rear lateral movement.
I just kept my front pressure normal level, as I know too little pressure in the front will cause more lateral front movement on grooved tarmac.
What you basically say is I should start my track session with cold tire pressure front 28-29 and rear 34-35 psi, which would equal around 33 and 40 with hot tires ?
I've only done 1 track session with the car, before this weekend, and then I felt the OEM pressures were too low. I got tire squeal and understeer in every turn....
I had a set of 17/18'' wheels (215 and 265 width) with me to the track. I filled both front and rears to 40psi cold tire pressure, and the professional driver testing the car for a car magazine, was very satisfied with the cars handling. Calling it "neutral, on the edge of boring"
Amongst the experienced track NSX drivers, the OEM difference in front/rear tire pressure (around 7 psi) is still maintained ??
How can I get hold of the collars from Al Terpak ?
