so my rear struts are starting to leak and its time to get new ones. i am going to upgrade them and i dont know what ones to get the KYB AGX Struts or the KYB GR2 struts. i am not going to replacse the springs. I do alot of autocross and i do tend to off road my car alittle. (putting subarus rally heritage to practice) so is it worth getting the adjustable strusts or not. and do i have to get new springs if i get the adjustbale struts. i would like any info u guys got so post away

 

If you got OEM springs, then GR-2's will save you coin and are about 15% stiffer then OEM ~ or, about the same as the AGX set at 2(F) 4(R). This is from KYB themselves...

 

If you autocross and go offroad, and have the little extra money, I'd say go for the AGXs-- you can dial them up for the track, then back down to 'stock-ish' for off-road and general street use. If the budget is tight, do what NW_OBS recommends and just get the GR-2, as it's essentially the same strut.
