Project Civic EF Racecar: Part 3 – Preparation For First MPTCC Race

  • ClintBoisdeau

,

Swift Springs supplied 14kg, 7 inch length, 60mm ID springs for the front coilovers.  During the Buttonwillow test, I ran 12kg springs up front with no sway bar.  This setup was on the soft side and a bit lazy during transitions.  With these 14kg springs, and a OE Civic HF model front sway bar I acquired from fellow EF Civic racer Tom Liang, the front end of Project EF should have sufficient roll resistance. 
Replacing the 10kg rear springs, are Swift 16kg variants in the same dimensions as the front.  During the test at Buttonwillow, the ASR rear sway bar had to be cranked up pretty high in it's adjustment range to get close to the desired rotation. My decision to significantly increase the spring rates in rear will allow the sway bar to be ran at a softer setting and not have to depend on it for the handling behavior I'm looking for.  
The external reservoirs in all their shiny anodized blue glory.  Such a design gives the dampers a larger heat capacity for more consistent motion control capability over a longer period of time.  It also allows for more travel internally.  
The adjustment knob for compression damping is located on the top of the external reservoir.  The adjustment clicks are clear and definitive.  Also the knob itself is large enough as to not make it difficult to adjust in case you have to mount the reservoir in a somewhat remote and hard to reach section of the car.  
The rebound damping adjustment remains in the same location on the top of the damper itself as it did in 510 series configuration.  Much like the compression damping knobs, adjustment clicks are easily decipherable by feel and sound for precise tuning of the suspension.
