Ron, your numbers sound reasonable.
Wes is right. I look like I'm about to roll my car over compared to Kevin's suspension...

Aftermarket suspension:

Good data points, Ryan. I wasn't following what Karl was running that closely.
So, comparing myself to Karl, it looks like I have up to 3 seconds in driver aptitude since I was running the Hankooks which are similar to the Azenis, provided Karl was giving it all there was to give on Saturday but consider if he has suspension mods and weather differences between the two days.
So, no votes for just working some more on the driver (data acquisition)? Did you get a chance to use that data acq device over the weekend, Ryan?
It sounds like I could find a little more by improving the nut behind the wheel but not as much as I think. I just keep visualizing the Top Gear episode where Sir Jackie Stewart "educated" James May...and keep telling myself, it's in the driver...it's in the driver...but bolting on some parts for quicker laptimes definitely has its appeal.

My "aftermarket suspension"
KYB adjustables: F @ 7, R @ 5
Springs: F - 440 lb/in, R - 275 lb/in
Sway Bars: F - 7/8" Adco, R - Stock '93
Tires: 225/50/R15
I ran the above with 14" tires. I found it difficult to have confidence in higher speed curves with the car...and it WAS slower. Going to the 15" tires made a BIG difference in the car's handling and resulting confidence it gave you. One of the best changes I made.
At this past weekend's TestnTune, Karl Shultz thought the car was still rolling a bit more than it should. He suggested a bigger front bar, 100 lb stiffer rear springs and no rear sway.
I agree with the front sway, but won't know about the rear changes unless I try them.
Ashraf, you need to get some GC Coil Overs and stiffer springs. Lower the car to about 12.5 in the front and 12.75 in the rear. It'll make a big difference.
