I think I'm done with modifying the car until it goes to 100% track duty in a couple years. I'll either use zipcar or buy a 123d over there as a daily driver, depending on how much my job wants me to travel.
I got an Akra Evo system installed and while the sound is different the power's definitely there. The car's already a little scary with how fast it is and with the Evolve tune and the Dinan stage 3 suspension I'm pretty sure it's going to be ahead of my personal limits for some time.
Now if I can just find someone who can enable MDM on the traction control, the car will be perfect.
