seriously though the sachs dampers are awesome for the trophy, you can always change the springs though if your wanting a lower ride height?!
its not really worth changing to the like of leda and bilstein unless u knacker the sachs and renault havent got any spares to replace them
rear strut braces only work if welded to the strut turrets so it just depends how hardcore you are, russ at gasperformance does some nice proper rear struts, the omp, k tec ones just bolt to the strut tops so dont really anything for handling as they move with the struts. they are more for aesthetics
the same goes for front strut braces you can get loads ie omp, sparco, ktec but to perform properly you need to bolt or weld them in and not use the self tappers they come with as these dont have much rigidity, look at demon tweeks or k-tec for them
whiteline do a front and rear antiroll bar, i now a lot of the aus clio lot have the rear one and rave about it but appartently the rear end likes to step out a lot more with these fitted. do a search for whiteline as there was a review from a guy selling them on here a while ago
hope this helps fella
