So '14 came to a close and I wanted to try and run with the staggered tire setup a little longer. The problem though is I didn't want to buy wheels twice, so just opted to make the jump to a square setup that fit the Stoptech front kit. I had the stoptech kit sitting in a box, and wasn't thrilled with how the oem brakes felt, nor the bad pad wear. Getting 4 days out of a set of front pads blows, and on a square setup with more grip up front, they'd probably burn up even quicker. I've seen locals get 2-3 days on the oem brakes with a square setup, so I knew that the move to a square setup means a BBK is necessary for me. It's a safety issue for me and tracking on a square setup with oem brakes just doesn't seem wise (assuming you aren't just putzing around the track).
Finding decent looking wheels that didn't require rolling fenders only leaves you with a few choices. I thought about the TSW Nurburgings and the Interlagos. I ended up getting the Interlagos 17x9 +63 and a set of 255 Dunlop Z2's. I wanted to stick with the original Z2's so I could have a better comparison when moving to the square setup. I rolled the front fenders for safety, and needed a 3mm spacer to clear the Stoptech calipers. I found some OEMish looking center caps and used them over the TSW centercaps so the wheels look OEM to the average joe. I have been strongly against rolling fenders, but I opted to roll the fronts because I didn't want to have a mauled fender. It was pretty easy work. Just heat up the fender with a heat gun and roll it.
Wife's Christmas present for '14. It ain't no SOS turbo kit, but better than nothing like most years
Here's a shot of the car with the new wheels:
Here's a shot of the Stoptech kit installed. The wheel weights on the inside JUST clear the caliper, and by JUST I mean w/in a couple mm's:

The stoptech brakes and specifically the calipers are massive. Some will knock them for their heavy weight, but they're proven and affordable. Seeing as the car is still a street car and I like driving it on the street, the OEM spare is now useless with the stoptech kit, so I looked into a solution and found the DC5R spare fits.

The downside is that you need to keep the spare deflated and it still protrudes out farther than the OEM spare, and you need a large spacer, but it fits (sorry not pics of the test fitting). In a pinch I won't be stranded.
Setup wise I opted to buy some hypercoil 11kg/mm front springs, and keep the KWV3 rear 8kg springs and see how it does. In hindsight I probably should've just bought 12k/10k, but hindsight is 20/20. I also swapped the rear bar back to the OEM '06, so I'm now running '00 FSB and '06 RSB. The car felt good on the street, and turn in is amazing, but I had to see how it'd do on track. Putzing around on the street I also found that VSA now is completely useless. The car turns in so well now (with maybe the slightest hint of oversteer) that I think the VSA system plays it safe and kicks in on even semi-putzing on the street.
I've gotten used to turning it off as soon as I get in the car now.
I did install some Megan racing offset lower ball joints to add a little more camber in the front. I think I'm running about -3 in the front and -2.5 in the rear.
Summit Point- Shenandoah May '15
Here's a video from the event. Had a ton of traffic considering it's Yellow group. The square setup is awesome and I understand why people love it so much. Turn in on the car is absolutely amazing. On the old staggered tire setup you turn the wheel, wait a second for the suspension to compress and for the front end to move. Now it's almost instantaneous. You turn the wheel and the car just goes. The bigger tire up front makes for more consistent braking in the brake zones which is a huge benefit as well. Also when countersteering, the larger front tires makes catching the rear a lot easier since there isn't this "delay" from turning the wheel and having the front end respond. I can imagine though on higher speed stuff you gotta be careful with turn in because the increased lift on the rear could make for a less stable rear.
Running the PFC pads w/ the BBK, I found it easy to lockup the front tires and it took some getting used to. I had to adjust to the BBK by using less pedal pressure and pushing my braking zones later. With the old OEM brakes I had to use a lot more pedal pressure. As I get used to the brakes I can push the braking zones farther. Towards the end of the video I put in a new best time of 1:43XX. My last lap I missed a shift which would've been a good 1:42.
Almost caught up..
