The only time that the 40s in the rear worked better for me was when I was running heavy rear diff oil. I later found that my car was easier to drive and faster with light rear diff oil and 45 shore Ipanemas in the rear.

I have used 45s in the rear before. However, it was very cold racing this past weekend (high temps did not get out of the 50s) with below freezing temps in the morning with 20mph+ winds blowing. The track took a long time to come in due to the cold temps and conditions. With 45s on the rear with my setup, the rear was sliding in the corners, at time, spinning out. So, I changed to the 40s and that did the trick (started with 45s on all four corners). When racing in Memphis, TN, I had to run 40s in the front and 45s in the rear. My car was on rails with that combo and I have TQ both races I attended.
