Ok...I keep bouncing back and forth between these two and wondering what the "real world" experiences are. I don't "plan" on doing any track days but do some spirited touring and would really like to go a little lower than M030. One major concern is that the specs for the X74 looks a bit lower than the PSS10 and lacks the adjustment. Whats you're experience? Thanks?

 

I have the X74. Love it. Chose it because #1 it is Porsche parts and #2 because it is non-adjustable. I track 3-4 times / year. It really flattens the car around corners. On the street it not harsh just feels tight. The height is not bad. Speed bumps and parking ramps need special care. Gert at Carnewal is where I got mine. Hope this helps.

 

i also prefer non adjustable suspension. otherwise i'll get all caught up in adjusting it and trying to perfect it. with the x74 you install it and forget about it.

 

I have got the X74 kit on my 2000 c4 and for the money it is an absoutely joy and improvement.

 

I love my pss10's. I like the fact I can stiffen them up for track days.
