S.Tech Spring testing on the 2010 Mazda 3 has been completed.

For testing we used currently available TEIN Japan High.Tech Lowering Springs (gold colored springs).

The final US Spec S.Techs will be available sometime in the Summer of 2010. The specification will differ from the TEIN Japan spec springs we used for testing due to the differences between the US and JDM model vehicle.

Expect the ride height drop to be: Front -40mm and Rear -40mm

The actual drop may vary by models due to the weight of different components (ie Transmission, Packages, etc.)

We take measurements at all positions of Compression and Rebound with and without the tires installed.

Above we have the tire installed and damper fully compressed to check for any clearance issues. Our products do lower your vehicle a considerable amount as compared to stock and we wouldn’t want any unnecessary damage to occur due to too low of a ride or too little clearance between parts.

Note: these are the Japanese Spec Lowering Springs, our final US Spec S.Techs will be Green.
