Question
Hi . Dan, Thanks for the response. Just a double check because im confusing myself with my tyre defonitions.

O.S.F (nearest centre of track positive camber)
N.S.F (negative camber)
O.S.R  (positive camber)
N.S.R   (negative camber)

mid = middle of tyre
i/s = inside of tyre closest to car
o/s = outside of tyre furthest from car

Tyre temps

N.S.F  o/s 136
      mid 127
      i/s 137

O.S.F  o/s 99
      mid 118
      i/s 125

N.S.R  o/s 105
      mid 116
      i/s 126

O.S.R  o/s 93
      mid 109
      i/s 112

 Thanks for your patience.

I stood next to jackie stewart in the pits at silverstone once..  still remember it... cheers mark  

Answer
Yes, your negative and positive cambers arre all correct.

From the temps.
you should add just a little air pressure to the NSF

Reduce the pressure of the OSF but just a little

The rears seem to be alright though I might reduce the pressure in the NSR just a smidgen

You're welcome for the patience, I actually enjoy this- - does wonders for my ego. Let me know how you're doing amd feel free to use my real e-mail , DNLDDY@AOL.com

Best Wishes

Experience

I have been racing for 20 years, I have been the Central Florida SCCA Regional Championship points for 5 years running, and won the championship in my class 2 times. During my first start in the 60's I won many solo awards and the State Championship Drags. I serve as a senior instructor for SCCA, and have taught in Mercedes AMG events at Daytona, and Dodge Viper Days at Sebring International. I have been in the thick of the competition for all of my career. At one time or another I have driven race cars at speeds nearing 195 MPH. It's quite a ride !
