The Spoon Center Drive Civic: 2017 Changes


Here is a close-up view of the gusset Chris Eimer fabbed up to stiffen the front frame rail, which is largely just handing off in space.

Chris also added this 1.25″ chromoly tube coupling the shock tower to the front of the frame rail to provide more stiffness to counter torsion and aero loads.
The KW Motorsports shocks were revalved and the springs were replaced with softer 18 kg front and 24kg rear. Previously from Japan, the car had way stiffer front and softer rear springs, which didn’t make sense considering the rear suspension’s motion ratios.

With the new sway bars, spring rates and shock valving, the car was much better in the bumps and was more forgiving to drive.

The old Garrett GTX 35R was replaced with the latest GTX 35R Second Gen. This allowed the car to make the same 440 hp on 3 psi less boost, reducing the wear and tear on stuff. The second gen is basically the same kickass GTX35R but with a much-improved compressor wheel with more efficient, higher flowing aero.

The new Second Gen turbo also spooled fasted and had better response giving the car an advantage out of the turns. Another fix from 2016 was to install a 4.7 final drive gear, which put the car in a much better part of the powerband.

In an interesting bit of drama- 4th gear and the final drive broke during Friday practice, forcing the team to pull an all-nighter to install a 5.12 final drive and a new 4th gear. This actually worked out, and the car was still in the powerband, just using 6th gear more.


Up to now, most of the changes done to the car were just to fix things that were rushed and not done to the fullest extent in 2016. Now to get to the one area where additional speed could be found- the aero.

In 2016, Dai complained of a lack of high-speed front grip and understeer. Since this seemed like an obvious aero issue, the team focused on adding more front downforce for 2017. There was a caveat though. Since there wasn’t any budget to build an engine with more power or a transmission to take it, more downforce had to be created with as little drag penalty as possible as at 440 hp. The Spoon Civic has less than half the power of some of its competitors and more than two hundred less hp than the next closest car in the FWD unlimited class.
