Well...its definitely a valving issue. After a short track day (3 20 min. sessions) and so street driving i'd say 90%-95% of the bounce is gone. It doesn't matter if its sport or touring valving for what we are paying it sux. It finally rides like an M should in my opinion. That being said if i could do it all over i would have just purchased a used set of coil-overs and had them dynoed and rebuilt before installing since that's what i ended up doing except my set was new.
