The Spoon Center Drive Civic: 2017 Changes


In 2016, there was some confusion with the driver and crew about feeling which knob to turn to adjust the hydraulic bias and the mechanical proportioning via the balance bar and how to distinguish the knobs by feel.

The knobs were offset and the correct directions written on them to avoid mix-ups!

All of the small details made a huge difference in how the brake performed and for the first time the brakes worked correctly, and Dai had no complaints. Some minor bias adjustments were made by the crew after some minor rear wheel locking was observed in some turns and due to the high temperatures the rear brakes were generating.


The stock front swaybar was replaced with a 2-way adjustable part special ordered from Australia by Whiteline.

The Whiteline part has about 60% more roll resistance than stock in the rear hole and 110% more stiffness in the front hole. In testing, the front hole was chosen to attenuate some high-speed oversteer without having to resort to increasing drag by adding more rear wing.


A Whiteline rear bar was used in the rear. It is three way adjustable.

It is about 180% stiffer than stock in roll at the rearmost soft position which is how the car was run and about 280% stiffer in the stiffest front position. You cant see the sway bars here, as they are mostly hidden by the car’s flat bottom aero.

Running stiffer bars was part of the strategy of getting the car more driveable and to find more grip on rough US tracks. The car was sprung extremely stiffly as it came from Japan. Japanese tracks have a very smooth surface and special high Mu asphalt. On bumpy US tracks, the car would skip and hop on bumps.


Spoon Japan had told us that in there testing it was found that the front of the stock unibody was not stiff enough forward of the shock towers for torsional loads, and it would also start to bend from aero loads.

Eimer Engineering added this gusset to brace up the front which was subjected to a downward bending moment from the spiltter.
