I have, from pavement to wheel:
Falken Azenis RT-215 195/60-R15 on HX wheels, 35psi front, 40psi rear
Ground Control Coilovers (250f/350R I believe), car at 4.5 inches
Tokico Illumina Shocks, 3 front, 5 rear
The wheel and rack are stock, but I do have a smaller Momo 300mm wheel I need to get a hub for. I really want to get it in, I'm getting a good workout with the Si wheel being so large. Also, with the Falkens, if you have the opportunity to leave between runs, go heat them up in another parking lot. They're good for about a minute hot, then they feel really greasy. This was perfect today, the best times were just under a minute, I ran a little faster in my car and a fun run, but the tires were heating up a lot more in the last few turns.
