Track Torque in Tockwith (Near Wetherby) Are your best bet but not cheap!
They charge £80 for the first hour and £50 per hour thereafter but a Clio shouldn't take more than 1 hour, Just give everything a blast of WD40 before you go so that it's easier for them to adjust Corner weighting is an additional £50! They will be able to give you advice on what settings to use although you can also get that from this forum although everyone has slightly different idea's I used to run 30 min's of toe out (0.5 degree, roughly 1mm 15" wheel) 3.5 degree's camber and standard on the rear. The biggest difference I find is getting the ride height right and that is where you want to get a pro looking at itCheers Guys. Some good recommendations here.
