It's held up pretty good.. I haven't really beat on it to much yet.. Just the odd jumping crash..only thing I've broke is I broke the shoulder off one of the steering rack bearings.. But easy fix by adding a washer under the head of the screw..
But one thing I noticed is you have to keep your eye on the hinge pins for the knuckles. They use a set screw in the arm to lock in the pin but at the end of each day they have started to walk out..
If you plan on gettin the kit.. Don't bother with the kit shocks, get a set of the proline powerstrokes, and upgrade the tie rod and camberlinks to something stronger.. After 1 race day it's pounded the rod ends out and the camber links are pretty sloppy now..
