Hello, I'm replacing my front anti roll bar (body to bar bushes) very soon with a kit. The bushes i need are 20mm dia. What im confused about is why does the kit come with the long bolts ? shown is this link http://cgi.ebay.co.uk/AUDI-A3-TT-FRONT-ANTI-ROLL-BAR-BUSH-KIT-/220537482801?cmd=ViewItem&pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item33590eee31#ht_900wt_704 The kit im buying is a Febi (great quality, German built). This just comes with bushes, brackets & bolt for bracket. Why does the ebay one come with the long bolts & nuts.
