New 928 Coilover suspension option!

[MarkRobinson]

I've been working on this for 1/2 a year now, have it all down, just fitting/finishing the rest of the pieces to make a nice product.

After owning 8 928's and performing suspension upgrades to most of them, I've determined the following:
1. Factory springs are horrible: soft, often failing, too large diameter for quick installs
2. Shock options are horrible: Bilsteins are too blah, Koni's are great for stock ride-height cars, but once the car is lowered a degree, you're dampening ability is compromised as the koni body is too tall, so the piston is already near the bottom. A 928 lowered 1.5" has basically very little suspension travel, maybe 1/2"
3. Factory spring perches are mostly corroded as the threads are too small, sometimes frozen, hard to manipulate, and even so offer only ~2-2.5" of height adjustability.
4. Factory upper mounts are heavy & contain too much rubber which compresses over time, making "quick" ride height adjustments virtually impossible.
5. With Koni's, the adjusting is a PITA and w/o any special tools, once you're set, you're set. I have the 928MS tool but haven't used it in 4 years as I bought the wrong one. Still, on lowered 928 its a moot point.

My design:
A. Eliminates heavy upper rubber mounts with solid light-weight steel upper mounts. No more settling issues. (pictured mounts are prototype and finished mounts are powdercoated & do not allow light to come through)
B. Uses modern street/track shock (manufactured by QA1 & Carrera) (circle track, sprint car, drag racing, street rods, etc) & features a 12-way external adjustability knob for compression/rebound
C. Uses modern, lighter 2.5" coilover springs for easier installations. Still testing what springs I'll recommend, but there will be many options.
D. Uses large-thread coilover collar nuts for finger-adjusability with 10" of total ride height adjustability.
E. Lifetime warranty on Porschesolutions Manufactured parts, and the Shock manufacturer offers an excellent 1year warranty & offers rebuildability as well. Every part is either anodized or powder coated for corrosion resistance & easy cleaning.

Looking for a target price of roughly $1400 for the entire setup ready to install. This *may* change but probably wont.

Here are a few pictures.

Looks great!

thanks! Course the idea was not beauty, but to make a better solution that's also lighter & still affordable.

If Koni's are 750/set + springs ($300shipped)< you're in for over 1100 & still have little adjustability, dampening travel, possibly corrosion-siezed spring perches, and failing springs & rubber mounts.
