I researched threads on here for an install for me, and I am leaning towards JIC because if the bump stop issue that some people have had with the pss9's. If I want to drop my car to GT2 dimensions, there may be problems. JIC does not have that issue, so it seems. I know a few people on here have not had the bump stop issue with the pss9, but from what I have read in past threads, there are many that have when dropping the car down.

 

I dropped about 1.25" on the front and 1.5" on the rear with the H&R coilovers. Ride quality on the street is great. No complaints and very happy with it.

 

No bump steer problems for PSS9's or PSS10's as long as you don't lower the car more than 1 1/2 inches. That is where JIC's have a clear advantage, plus they offer different spring sets for street and track.
