I think it may be my posting you were refering to?! re bolting and welding
I had my local renault dealer drop the front suspension and do the job properly! (Its not as bad or time consuming as youd think) In my case it was bolting it in. Modern cars like the clio are disposable, they havent been designed to be pulled apart and rebuilt - as anyone whos had the interior apart knows, its never quite the same....rattles and squeaks creep in!
Ideally you should weld the strut brace in, its the no compromise solution that will give the best results, I pondered long and hard and decided it was too big a risk to take, once its in its going nowhere and could prove to be a serious problem when working on the car in the future. I used the OMP brace on my Mk2 and found it did noticably improve high speed cornering and aided turn-in (but only in the dry!) On my cup Ive yet to decide on which brace to use, I may even commision someone to make a custom brace without the stupid adjuster which is definitely a weak point.
Hope this helps????
BTW, my local dealer charged 2 hours labour to fit both front & rear braces, full guarantee on workmanship no arguments.
