Hi all,

I bought these springs to lower my car and before I install them I would like to ask some questions. Will I have a problem if I plan to install these on stock shocks/struts? Or will I need to purchase them?

Thanks

Nope...you will be fine. In for pics

I'm about to put a set on an '04 AP2. How do you like yours? I'll be using stock struts as well.

I have this on my stock struts, my 04. If you'd like some pictures, I'll post up if needed.

In for pics! I just bought Swift Sport springs and a spare set of ap1 struts to mount them to. I got the sport springs because they are slightly less of a drop, and more closely match the factory spring rates. My concern with the spec R springs was wear on the struts, and a possible bouncy ride.

Per Swift, the Sport Springs were specifically matched to an AP1 and the Spec R's to the AP2 CR. Has anyone done a review of the Spec R's for the S2000? I'm interested from a handling and ride quality rather than the drop.

I have an 04 AP2 and the Sport Springs look like they will move me closer to an AP1 setup than the CR. I don't want to increase over-steer over what I currently have.

So, comparing the "Sport Springs" to stock, they most closely match '04-'07 fronts, and CR rears. The "Spec R" most closely matches the CR front and CR rear, but is more over-sprung than the "Sport" is.

the sports will actually induce more oversteer, due to the rear bias, moreso than the Spec Rs...jm2c.

Thanks guys! Found a review here: https://www.s2ki.com/s2000/topic/933...t+spec+springs

Turns out the Forum search has issues if I put special characters like "Spec-R" as the parameters. Hopefully they won't mess up my AP2 shocks, would probably replace them with CR shocks if they did.

I'd just go with koni yellows if you're gonna spend the money
