All the parts of the lower end coilovers are manufactured from the same spec material, probably by the same manufacturers then distributed to Jamex, Jom, HotTuning etc for assembly.
For £160 with a 3 year warranty and delivered to your door you would be silly not to go coilovers, you have the option to raise/lower the car until you are happy with it.
I dont doubt that shock/spring set is a better produced option, but for a daily, coilovers all the way

Just an example of certain manufacturers using the same equipment, Ginetta cars use NON oem Ford track rod ends for some of their cars FACT
