While those shocks do offer a "mild" step up in performance, the koni's and the tokico's aren't adjustable and are billed as "sport" shocks, not performance shocks. The bilsteins are good shocks, and fall under the "few" that are out there. Given the plethora of high-performance shocks available for the G3, I stand by my statement that there are very few "performance" shocks available.
I wonder why they don't just list the civic set as fitting the G2?
