Civic Suspension Work

Update by David S. Wallens to the Honda Civic SI project car
Jul 10, 2002

We’ve gotten a lot of work done on our Civic Si, and it’s starting to handle like a race car. We converted the springs to a coil over system from Ground Control with some pretty aggressive rates. How does 550 lbs./in in the front and 900 lbs./in in the rear grab you? We also raised the car approximately 7/8” in an effort to gain back some suspension travel lost when the car was lowered “to look good” The combination of the raised ride height and Ground Control camber plates has effectively doubled our available suspension travel. This, my friends, is noticeable.

During our recent tire test with a Neon ACR prepped to STS rules, our Honda acquitted itself well. We lapped the test track at Michelin 1 second faster in the Civic than the modified ACR Neon on identical tires. It looks like we’ve rid ourselves of the handling demons!

Per took our Civic to the SCCA Solo II National Tour in Peru, IN this past weekend. The Civic wound up in the last trophy spot in this tough 15 car class. There was some difference in the car’s behavior on concrete versus asphalt. What was a neutral car on blacktop became an understeering car on concrete. We’ll be addressing this issue before our trip to Solo II Nats (which is on concrete)

We’ve also ordered a battery relocation kit to get our cornerweights more in line with what they should be, and to move some weight off the left front of the car. The car seemed to turn better to the left than the right, as the car’s weight is biased heavily to the left with the driver in the car.
