Melbitoast,
yes these increase handling and control and more importantly give you options to change your suspension in case you want to make small adjustments.
Spring Rate is the rate at which the spring responds to a given force. Think Stiff or Soft. Sometimes correlated with how a vehicle rides, but not completely true as shock damping plays a more measurable roll.. This more impacts how far the suspension travels and thus when you lower a vehicle the rate goes up so that travel us reduced to ensure bottoming does not occur.
Shock angle is the angle and more importantly the point of connection of the shock to the control arm. By moving it in or out you change the leverage of the shock and spring on the motion of the control arm. Moving out adds leverage (like increasing spring rate) and inward is similar to decreasing the spring rate because the arm has more leverage against the spring.
Camber of course is the angle of the wheel as viewed from the front or rear.
Negative camber would look like this /--\
Positive camber like this \--/
and neutral camber or 0 camber |--|
Other features like replacing a rubber bushing, which has slop due to the rubber being compressible, with a spherical bearing, which is ridgid, adds to the control and location of the suspension during travel. Think of it as the difference between wearing a shoe with a thick sole that offers no feedback on rocks vs standing barefoot. The thick-soled shoe offers more comfort certainly, but it would not offer the same feedback as your foot which could feel every fine surface. In the same way the spherical bearing also will conduct more noise and vibration since the rubber is not there. But this is a choice you can make to improve handling. The subframe mounts, which have a much more significant amount of rubber in them, will damp almost all of the additional noise and vibration created by this replacement.
I hope that answered some questions...now onto an update. Sheetmetal is here. Both versions are shown here. The Race version is approx 6 oz lighter per arm than the Entry Economy line shown without dimples which is what I will offer for the ISX50 platforms.
E^2 Line is MIG welded and ground the Race version is TIG welded and untouched. Race will also feature the top box brace that closes in the treangle towards the inner mount...shown later.
I will weld up complete assemblies this weekend, or what I have time for anyway. Hopefully making a dent in preorders so they will ship soon.

several setbacks on the manufacturing side. Hoping to get them next week. A little longer than expected for sure.

Verified today, so now if I can get the additional pages built it should release in the next few days. Lots of media and the install guide gotta come together. PM me if you would rather just paypal.

Here is the final outer clearance and the mocked up fitment (sway and bolts not connected/torqued).

No the rear sway endlinks will be a separate item released at a later date. These will work with the stock endlinks however and still give three preload options.

These are released FYI. I will extend intro pricing another month or until I am sold out of this round of parts. Toe links are on BO until mid next week.
