Bilstein or the GR-2 KYB's will be great upgrades. I also like Koni's. As Josh stated I would do all 4 at the same time. As for springs...what kind of mileage are on yours? If you're not looking to lower the car you can probably keep your stockers. SFC's and a strut tower brace will be nice additions to the car as well. They will make your ride seem a little more "harsh" and not as smooth however, but you're actually making the car better. Everything will be a lot stiffer as you are eliminating the flex from the unibody which will translate into you feeling it more in the cabin but the handling improvement is worth it. If you decide you're interested in any Spohn parts let me know as I sell them for 10% off, or I believe Josh is a dealer for UMI as well.
