The K-Sport I bought are Effing Solid, light weight and totally adjustable.
Here is a review I did elsewhere,
I recently upgraded the suspension on my Protege5 from Tein-SS to K-Sport.
TEIN SS $1400.00
TEIN PRO
-Survived 160,00 KM without Issue
-Almost no signs of Rust
-Easy to Setup
TEIN CON
-Steel Construction means HEAVY AS ****
I seriously did not know how heavy they were until I took the K-Sport out of the box
-Only Adjustable for Spring Height and Rebound.
-NO CAMBER PLATE
(Deal Breaker) had to reuse OEM Pillow Mount and Bearing.
-Good Solid but comfortable ride.
K-SPORT Dampener $900 - $1000
K-SPORT PRO
-Lightweight Aluminum Construction
-Camber Plate on 4 Corners Included
-Threaded Shock design means universal replacement is easy
-Separate Shock/Spring height maintains full travel when running a lowered car
-Fantastic Ride
K-SPORT CON
-More deliberate setup as there are more variables possible.
Use a Micrometer or count threads to verify that the Left and Right sides are IDENTICAL before they are installed.
- End links required some more creative thought.
