which ones are they? are they cheap cheap ebay ones, Jamex, or CMC ? My van has been lowered before i bought it and the ride is terrible, really hard on the rear end. I'm sure my old van on CMC 60mm shocks and springs was much better( well i think from what i remember ). So I am going to invest in new springs probably T4RUS or CMC again but i want to know what they are before I potentially make the same mistake if it turns out they're already CMC or T4RUS. Do any of them say anything on them as to what they are? All i have seen so far without proper investigation is they're red..
