IMHO if your just buying regular gas shocks and Not coil overs, the Best thing to do is buy a set that is a "Matched" set of shocks & springs because any company who sells their own springs, their shocks are valved to match and this results in better ride and performance.
I seen where you were thinking of the 17" TTT wheels, Keep in mind that those are some Heavy wheels! Less rotating mass the better!!
IMHO if your going to coin up for some fancy one piece wheels you might want to just save up a bit more for a good 3-piece wheel (You get what you pay for). In the end these should be the last set of wheels you will buy for the car. Three piece wheels can easily be sent back to the manufacture to be re-hooped for a different BackSpacing, Narrow the wheel or what ever you need and Most company's will even do this for free since you bought the wheels from them.
This eliminates being stuck with a certian wheel or having to buy two more because you made changes to your car and now realize they don't work!
Just my thoughts..
