Look what I found on Ebay the other week for $325.00. I'll start prepping them for SCCA next weekend and will show the steps. It will be my first time taking these apart, already have a good spring compressor but wish I had a table fixture.

Do you have a link? Those are most likely just the fe2 zok package. The fe2 zok spring is just a shorter stock rate fe3 spring and fe3 shock. They are all over ebay unlike the legit fe3 zok setup. Bought my same set as that for the same price last year.

The other way to tell is from the spring tags from the suspension usage thread. lt blue and lt green are le5 zok. orange and yellow tags are lnf zok.

Went to work, won't be back till Friday. I will look then, I was going by the 2nd spring perch in the photo and that's what I received plus the company has a 99+ approval rating. Still it will be an upgrade over my base suspension.

Factoryoemparts? Thats where i got mine from and they are indeed the zok option for the le5 and not the lnf. The title is missleading since it does say "Sky Solstice Springs Shocks GM Bilstein New Set Z0K FE3", but its cleared up through the rest of the ad. Im not trying to argue with you but thats what I get from your picture and the price you paid.

But the second perch is there on both setups. It was an option to be removed at the dealership prior to sale if the customer wanted. Was only there for clearance during assembly and shipping purposes as it put the car close to that of the stock height.

I agree with this as per what my books says, but only on the ZOK suspension.

Not trying to argue with anybody. I just got home I drive truck.
The parts I received are (shocks) C646/15901220, C648/15901221. Which the LNF/LE5 both share.
The springs, 15906532/15906534 are listed under LE5 ZOK. The LNF numbers are different. From what I'm starting to see, the one thing setting the LE2 and LE3 apart are the stabilizer bars, lower control arm bushings and crossmember.

Yeah, the LE5 ZOK package is basically a stock FE3 setup only a little lower. The LNF ZOK is where the good stuff happens and is all new stuff except for using the same FE3 shocks for some reason.

So if I bought the LNF springs and put them on my shocks along with the other upgrades I made I'd have the FE3 ZOK package. I still need the poly bushings on the lower control arm. When I get the ride height adjustment sleeves I'll put the other springs on.

Yep. Though Id be careful with the bushings if youre trying to stay in a certain class within scca. I dont know the rule book, just by what Ive read on the forums, so youd probably want to ask someone that runs it regularly. They would know what you can and cant do with modifying away from stock zok specs and not get bumped into a different class. Things might have changed from what they tell you in the solstice handbook.

There was a rule at the beginning of 2013, bushings can be of any material. Since the ZOK came with stiffer bushing in the lower control hence the different part numbers for the n/a and the GXP I would still be CS class if I did change them. Not worried about what class I'm in already moved myself out of stock by putting in adjustable stabilizer links....:lol:
