I've been looking into upgrading my suspension. This is gonna be my first mod on my new 99 SH. I really would like an adjustable suspension like Koni Yellows but all the websites I've been looking at have Koni applications that exclude the type SH. In fact the KYB and Toyiko adjustable suspensions also exclue the SH. I'm guessing this has something to do with ATTS but I'm not sure. Whats the deal?
