What springs should I buy?

[Sam Wood]

I'm looking for some 40mm lowering springs for my 1.2 54 plate Clio Extreme
Before anyone says I want 40mm so please don't lecture me on how it wont look any different etc

Ive seen a few on ebay but Im unsure which will be best

I want the cheapest ones possible, but still have to give a nice ride

Link me to some please

Cheers, Sam
