Project EP3 Civic Si, Suspension Upgrades with Whiteline!
So everyone into Hondas just about universally ignores or even hates the dumpy EP3 Civic. The EP3 represents, to most Honda fans, the generation of Civic where Honda lost their brand identity and started to make cookie cutter shitboxes.
Who can blame them; the much loved sixth generation EK was the peak of the Civic's development. It was good looking, lightweight and featured excellent handling with 4 wheel, multi-link suspension.
The seventh generation EP was Honda's first step to decontent the Civic to make it cheaper to produce and bigger. The EP was supposedly designed to appeal to a theoretical early 20's, single, female, college graduate named “Buffy” who just got her first professional job. (Can you believe this is the BS the PR guys spouted at the cars intro?).
Well, it was obvious that Buffy was not a car enthusiast. The EP had dumpy, boring styling. McPherson struts took the place of the multi-links in the front suspension and flaccid handling and understeer was the name of the game. Honda Civic fans were heartbroken. To top it all off, the front steering geometry was designed for ease of fitting a steering column with no regard for bump steer.
As a result, the EP3 is the least desirable of all the Civics and probably why we got ours for so cheap. On the positive side, the EP is the least likely Civic to get stolen! One of the EP's worst traits is its handling, and we will do our best to improve it.
Previously, we have paved the way for better suspension by upgrading our EP3 with RSX Type-S parts, a 5-lug conversion, and bigger brakes. Now we are going to install some Whiteline bits to give our cars handling a needed boost.
The Whiteline bars are much larger in diameter than stock and add considerably to the overall roll stiffness. They also add more roll stiffness to the rear in proportion to the front to reduce understeer that the EP3 has in droves.
The bolts allow for 1.5 degrees of camber adjustment. We like to use the camber plates to set the steering axis angle and adjust that to minimize the scrub radius, which is critical on an FWD car. This is especially important for one with a lot of bump steer like the EP3. Too much scrub makes bump steer feel worse.
