Point

・Reducing the vehicle body roll delivers reliable and sporty drivability. Enjoy briskly driving feeling with a lightweight vehicle body.
・Lowering the vehicle height narrows the gap between the fender and tire to create better appearance.
・The front case length upper limit is the brake hose’s movable limit, and beyond its lower limit, the vehicle body may come in contact with the tie rod.
・If the vehicle height is increased more than the test condition, abnormal noise may occur when going over a bump in the road or excessive body roll is caused since the rear rebound stroke is short.
・Replace the 10mm collar with the provided 16mm collar to avoid unnecessary contact between the ECU and front upper’s shaft. After replacing the collar, adjust the overall length by 6mm. (Refer to the test setting data.)
・Before installation, adjust the adjuster thread length to approximately 200mm since the rear rebound stroke is short.
・This product is compatible with Mazda Carol (HB24S) FF model.
 
●Required Modification
The factory rear bump rubber must be cut and modified in order to install this product.
