Project STi Part 2, We test and witness the birth of Our Suspension System

,

The bars are then cleaned in an alkali bath to prepare them for paint.
Next the bars are preheated in a giant oven to get them ready for powedercoating.
The part is positively charged and dusted with negatively charged plastic powder. The opposing charges cause the powder to be attracted to the part like steel to a magnet.
The coated bars go back in the oven. The heat melts the powder and causes it to flow and gloss over.
Completed bars ready for packing.
Bins of components wait kitting and packaging.
Here parts are kitted into assemblies.
Whiteline stuff ready to go.
The handling packs simple and inexpensive parts list goes a long way to improve the cars cornering prowess.

The Whiteline parts also cant the lower control arms forward to give the front suspension more positive caster. Positive caster causes the wheels to gain negative camber on the outside wheel in a turn, right when you need it the most, a good thing. Think of a parked chopper with the wheel flopped to the side. That’s an extreme example of negative camber gain with positive caster. When the wheels are pointed straight ahead there is no gain in negative camber, good for even tire wear. Positive caster also helps steering feel and straight-line stability. The Whiteline parts give ½ of a degree of positive static caster to the suspension which can run up to 1 degree of additional caster when the wheel is turned. We installed Whiteline’s Comfort version of the kit that has 70 durometer urethane bushings. Later when we get more serious with the suspension development, we will replace this part with the 90 durometer race version of the part which rides rougher but has less deflection.

Whiteline’s steering rack bushings should be mandatory for anyone who buys a STi. EVO like steering feel for only a few bucks.
