Testing Coil-Over Performance Gains

Update by John Rogers to the Mazda MX-5 Miata project car
Apr 26, 2010

Project STR now carves around corners.

Now that the KW Variant 3 Coil-Overs are installed and the car is realigned, we found a warm day to head to the track for a quick shakedown. KW provides starting recommendations for ride height as well as compression and rebound settings.

Using their out-of-the-box settings, we ran laps on the Tire Rack test track with the OE Bridgestone tires as well as the Dunlop Z1 Star Specs. Not surprisingly, our lap times on both tires were faster than when we drove with the OE suspension. We were a bit faster on the Dunlops, which is good news: We keep closing the gap to the front-running cars. Subjectively, the car now feels livelier and responds quickly to driver inputs.

Next up: bigger anti-roll bars.

Those tires look huge under the Miata

How much faster were the lap times with the new suspension?
