The Shuttle's suspension is upgraded with the components listed below.  Here are the alignment specs in use.

• Tein HA coil-overs (24-way and I maintain them on position 8))
• Whiteline adjustable rear swaybar (See warning below!)
• Whiteline polyurethane bushings front and rear

Tein HA Coil-overs - The spring rates are 10 and 7 kg /mm, or 558 and 392 lb/in, front and rear, respectively.

Whiteline package: KGT4H

• Rear Adjustable swaybar
• 2 Poly D-bushes for the front 25mm swaybar
• Polyurethane Rear Trailing Arm Bushes
• Front and rear Camber Kits
• Polyurethane Bushes for all the front lower control arms bushes

Installation

Installation is quite a snap.  Instructions: Remove existing strut/spring assembly; install Teins. 

Rear - I installed these while also installing the ST205 brakes.

WARNING!!!  Installation of the Whiteline adjustable rear sway-bar onto a GT4 that's equipped with Teins will result in a conflict between the sway-bar and the brake hose mounts on the Teins, which can quickly result in ripping the brake hose mounts from the struts, which is obviously not good.  I caught this conflict quickly by noticing the metallic thump-thump during the first drive following installation of both the Teins and sway-bar.  As a result, I reinstalled the original sway-bar until which time I could render a solution.  So, look closely at the following two photos and you'll notice I've created mounts which reposition the sway-bar linkage, which builds clearance between the strut and sway-bar.

Here's an image of the rear strut adjustment.  The view is of the top of the strut tower, just below the rear tweeters.
