Anyone help me on the new PI springs I just aquired. They are supposed to lower the front 35 and rear 30mm. the guy who sold them to me didnt seem convincing that they where for the 172 model, if this is so will they lower my 172 (35/30mm) or is that drop for the standard clio. As the 172 is lower any way will the difference be noticeable if i put them on.Any replies quickly cheers guys!!!!!
