Hey guys, I have a 2003 Lupo Gti and am looking to upgrade the suspension bushes to Powerflex ones. http://www.powerflexshop.com/car/volkswagen/lupo-1999-2006/powerflex-bushes-for-road-use-volkswagen-lupo-1999-2006?options=cart From here I am unsure what sizes to order for the Front Anti-roll bar bushes 18mm, 20mm or 22mm? and Front Anti-roll bar eye bushes 18mm or 20mm? Thank you!
