been alot of debate about them on the clio.
To be honest, i have one, and i cant say its made any difference...but i had it fitted at the same time as the H&R's so i dont know how much is purely H&R and how much could be strut brace if you see what i mean.
Realistically, if you want it to work, dont bother buying ure run of the mill K-tec and OMP kinda ones.... get something a little stronger, and its gonna have to be properly bolted, and possibly welded on as well for it to really have an impact.
Same at the rear, K-tec one looks good (i have it) but i really dont think it does much. More for the looks
