Hard to tell exactly how much gain there was, but it was so much better.
My best time on stocks all last year was a 2:34 in perfect conditions and driving at 10/10ths. (some of the trackdays, I was closer to 2:37's)
I got down to a 2:33 (theoretical 2:32 based on my best sector times) but it was very cold and I think most everyone was quite slower than their typical times (3-6 secs depending on the car/driver). I was also driving to 9/10ths learning the limits of the tires and playing a bit with their pressures.
Tires (Conti Extreme Contact DW) are fantastic in the wet, great in the dry with very predictable breakaway. The wider tires didn't hurt either.
The Eibach ProKit springs made a huge difference to the balance of the car, it is sooooo nice now with perfect balance (for me at least). Very good grip out of corners now with the softer rear springs (no more corner-exit drifting).
One thing I learned that was pretty surprised about was that it appears I have too much camber.
I am running -2.2 all around, measured tire temps and the inside of the tire was much hotter than the outside, indicating too much camber. Typically this would not be that much camber, but with the stiffer springs and our car with such a low centre of gravity, there is not much lean, so less camber is needed than your typical car at the track.
