Bought the local version of this from a local Auto Supply at 130 pesos (4pcs*130 only)

2 spacers opposite each other will approx lift rear suspension 1/2 inch, 3 spacers in triangular paths on the coil will lift 3/4 inch. Depending on your daily load, use only 2 or 3 rubber spacers for each spring. Remember to remove these modular spacers if your claiming warranty defects of the suspension.

Rubber Spacers will not last over a year, but for a hundred thirty pesos I can always change it every 6 months co'z it's till cheap. Many brand of cars have the same problem including top Japs brands this is the quickest remedy without you removing the entire spring assembly voiding the 5 year warranty.

Observation: Better than O-sulee in terms of price difference which share the same principle of restricting spring motion. Resulting rear suspension is much more sturdier and higher compared before.
