Billstein PSS9's
 

Anyone have either the PSS9's or just the PSS on their Z/G? I want to purchase a set from Adam@Z1 + some other suspension goodies (front/rear spc camber kit, sway bars, arc strut bar) but I need some reviews before I can spend anything on them. :)

I'm actually ordering the PSS10's tomorrow from Adam. unfortunately that means i cant give a review yet.

no, no one has installed these at all. please search next time

You didn't get any hits with a advanced search narrowed to this section on the Pss9?

Their are many owner comments that exist, including my own review.

Or did you mean to say,........Pss10 review's don't exist because it's too new?

I do not know of any Pss reviews, though the same search that will bring up Pss9 review's, might bring something up for the Pss.

Link to my own review.

Cut and paste from other Pss9 reviews

thanks guys :) next time ill search...i was just being lazy lol. will you still be my friend zo4? ;)

I also have the pss9's installed and i love them.

i just got these coilovers yesterday from another Z owner. Probably going to install in the next 5 days. I heard pretty good reviews about the ride quality but yea, i don't see many people with them.

Ditto

Wish they could go a little lower in the back but thats my only complaint (and its not much of one).

Just caught this discussion a little late. I posted this in the vender forum for PSS10 earlier;


I've had a set of PSS9's on my car for over a year now and I couldn't be happier. I cannot compare the ride to other brands, but I can tell you the ride is a bit stiffer than stock. It's more controlled feeling though. Drop was 1.5 all around. Limiting factor wound up being the rear spring adjusters. (If you remove these adjusters completely, a 2" drop is expected).

I'm about to get into Autoxing soon. I wish I could comment on their performance at the track, but I haven't been yet.

I thought about removing the rear spring adjusters but I only removed 1. Felt like there was too much movement in the spring if both were removed.

Agreed. Exact same here. -- Don't think I would want it any lower though.

i just bought my bilsteins used about 3 weeks ago. Yea, my friend and i got the suspension on and were so frustrated with all the adjustments. yea we also removed 1 of the adjusters in the rear. i think it's at a good height. the front however, when we first got them on... it looked super high so we ended up taking the helper springs off due to miscalculation. but it looks like there's more than enough room for the helper springs so i will be putting them back on. overall i think the ride is pretty good. pics of the height (front was raised the day after this photo):

what do the helper springs do? I just finished installing my PSS10's this weekend and I'm going in for alignment tomorrow. To be honest I'm not dropped THAT much, I could definietly go another .7 or .8 lower in the front and my helper springs are almost FULLY compressed. Is that normal?

yes ^

Is it me or do springs need time to "settle" anyway?

There are at least 2 people from the Mid-A rolling PSS9's on their cars. I am one and I can say that the reason I went with the PSS9's is because the other guys car handled every turn and twist and dig and dive we went through. I cant give you seat time review as I haven't driven my Z since they were installed but I am definitly waiting to check it out.

I have heard that they need time to settle, my question is should I get another alignment after they settle?

the coilover springs will not settle...if anything, its the factory rubber mounts that recompress a bit once they are reinstalled, but that happens within 20-100 miles at most.

OMG thats like once around the island!
Just kidding. Good to know and thanks again Adam for the excellent support.

i believe the helpers are there to keep your springs from popping out of the seat. i dun know if they help any in performance
