Thanks guys. With the stock height and "thin" 285/30 tires, the F.I. mufflers are already suffering some minor scrapes. Christian mentioned Swift springs, which offers a 1.2" drop for the front and 1" drop for the rear.
With that in mind, this is what I gather from your responses:
Easy: 245/40 & 285/35 (1.75mm wall difference)
Ideal: 265/35 & 305/30 (1.25mm wall difference)
Extreme: 275/35 & 305/30 (4.75mm wall difference)
Any of these setups will offer more sidewall than my current setup. For 265/35 tires, I need to look for something whose price and performance is comparable to the Hankooks.
I still have my sights set for Stage 1 TT with minimum 5-6 PSI for daily driving and 7-8 PSI simply because the boost controller offers a high setting. I park next to a GT500 at work, and I see the rear tires are 285/40. Wow! I think the owner mentioned that he can roast the tires in 4th at 40mph. Of course, that's not what I'm aiming for with a force fed daily driver haha.
[EDIT] I've decided to settle for 245/40 & 285/35 due to availability and the increased sidewall will allow for 1" drop using Swift springs. Thanks all, rep!
