I was browsing H&R's website and to my understanding from their application guide is that there ARE NOT any super sport springs made for the 2IS? Only the sport springs will work? Anyone have any info on this?.

Also, I heard from someone that putting on H&R sport springs will blow my OEM shocks within 30k miles?

 

I have checked H&R website and found the same; only sport version is available for IS250. But the sport vesion for our car is sufficientyly low for me already. If you want even lower than H&R then look at RoadMagnet.
