Just as a note on the shocks, and I know a few will disagree with me here, but maybe have a look into some Tein RS's second hand, then have them rebuilt (no longer in production, I don't think). I might look into this myself, as after driving Jack's car home from PI I was amazed at how compliant they were on the street, yet are obviously doing a good job on the track. I know they were modified by Racepace, so it's not just an off the shelf kit, but they were really impressive.
Sorry to go off topic, but thought it may be of interest.
