Not sure which to go with AVO are about £30 cheaper and lower the car 35mm.
I have just rang Eibach U.K who say the springs are £70 to trade and £116+ VAT to the general public, also that although they state it lowers the clio 30mm this is refering to a standard clio, due to the fact tht the 172 is already lowered as standard, you will only get a 10mm drop.
Think Im swaying towards AVO?
