Very high quality spring set that is ideal for touring and rally cars. Each color represents a differnt tension level. Blue=hard, yellow=medium, red=soft. Tamiya springs are of very high quality and their price cannot be beaten.
This spring set have 3 different tension levels and the colors are eye catching. The springs are standard in length, so the RC car ride height still maintained. This spring set is best matching with TAMIYA dampers like low friction aluminum damper set and TRF special damper set.
I bought this set and the four pairs set (53440) and, while these are good springs, the other Tamiya set is better. First, the white springs are a useful option for on-road and carpet racing. Second these springs are just better made and feel more consistent.
The colors from this set somewhat match the colors from the other set, but the springs are a little different in length.
On the other hand both Tamiya spring sets offer great value for money compared to most other springs.
