I have been building a car for some time now and the last obstacle was there was not enough room for the rear tyres,i turned them down bu then hit another probl;em,crown was touching down.After some thought i decided to venture a small crown and pinion set and it worked.The crown is 27z 13.7 diameter and the pinion is 9z for 1.5 dia shaft
