I had massive offset rims on my series, but it won't make much difference to the turning circle - the swivels just don't have the range - you'll get a little bit, but not much - the balls on series are too big and beefy, where they meet the axle flange is too big and almost at the limit with standard bump stops (the ball seal will run in free air). If they went a smaller axle bearing and reduced the ball flange accordingly then yes - but no, lr thought the 5kg axle needed a massive 10000kg bearing to handle the load :eek:. the uni joints will handle the extra angle - but you just can't use it.
BTW - the little bit extra you'll get is worth it though :)
