Ive got apex 40mm. Ive had the 1.216v versions on both of my clios and have been impressed by the quality. 40mm looks nice and gives a much better turn in, in my opinion. The wheels sit in the arches nicley. The rides is obviously a bit more bumpier, but in turns of hanlding is much improved. Got my springs off the forum, paid £40 inc P&P, months old like new. They retail at around £80, so new they are not too expensive and are £50 less than the eibachs.
Gonna get some pics, fitted the cup splitter, looks sweet, even my mum noticed the difference which is saying something, wasnt difficult to fit, did it by self with yellow pages to wedge it in place whilst I screwed it on!!!!
