Kit is installed, setup, and dialed-in.
I am running K-sport front kit w/their 560lbs springs. And K-sport shocks in the rear, with 550lbs GC springs in the rear. (Sorry, didn’t install the K-sport rear springs, which are 420lbs). I’m running 1” drop front and rear. This is a pic with the GC kit, but it’s identical with the K-sport setup.
Summary:
Love it, very happy with the kit. Works exactly as advertised... lots of height adjustments, good amount of stiffness adjustment, very balanced handling, no weird noises.
Height Adjustments:
You can drop from 0.75" to probably 2.5" (but you'll be rubbing all over the place that low).
Stiffness Adjustments:
The range is not from Lincoln Town Car to Z06 or Porch GT3... It's more like a little softer than FE4 to a little stiffer than FG2. Shocks have 6 full turns of adjustment (1-softest, 7-firmest). 7 is pretty firm, but not harsh… you can easily run 7 all the time, but I don’t see the point… save that for the track. I’m running 4 all around and it’s a little stiffer than the FE4. 3 is very close to FE4. I’d say 5 or 6 is FG2 (having driven WW's car a few times) 7 is definitely stiffer than FG2. I’m going to drive Calicadi’s or WW’s car in the next week… so will compare FG2s to these shocks back-to-back.
Handling:
VERY balanced… I’m very impressed with this car and the shocks… Caddy really has this suspension sorted out, you can go pretty stiff and not screw up the handling. At 4 or 5 you get basically 4-wheel drift…with just a hair of understeer, easily correctable with a little throttle. At 7 you get more understeer, but it’s still manageable with throttle (or run 6F and 7R)
Issues:
* Install is a pain. Not difficult, just tedious. Lots of raising, adjusting, and lowering the car to get everything setup at the right height.
* To adjust rear shock stiffness, you have to remove rear seat (8 bolts, not to bad, but still a pain)
* Can’t use Hotchkiss sway-bar.
* Some rear squat on hard acceleration, I think the FG2 load-leveling helped control this.
* I don’t think you can use Eibach race springs in the front, K-sport would have to change the top mount, and maybe the spring perch.
* Car could use much stiffer shocks for track use.
Answers to previous questions:
* Drag racers: No change in wheel hop
* Luna: No, this kit wont let you use 1st gear... give up that silly notion until you get the mini-tubs and put 315s or 335s in the rear.
* Urb: Yes, you can lower the car 0.75"
...will post install steps / tips in a couple days...
Actually, I substantially can. The 275s in the rear have helped a lot. However, I need to widen the rims, as 8.5" just isn't wide enough for the 275s...at least, in my mind.
