Going slightly off topic, the Williams relies on the full travel in its suspension to keep its wheels on the road as much as possible and hence give it its abilities over twisty and poorly surfaced country roads - so its best not to lower it IMO. Thats why Im not keen on lowering mine as although it will grip better on smooth roads, itll skip around on the B-roads I bought the Williams to drive on. My last two Clios were lowered and Id not do it again.
