I've had 3 sets of invos now and I'm lucky if they last 10,000 kays. I put a set of invos on the rear at the same time I put a set of atr2's on the front. The invos are now past the indicator and the atr's still have about 70% I'm not going to lie and say I'm an angel on the road, just the od skirt around a corner from time to time haha. Was thinking of trying a set of atr2's on the rear for the next set. Got quoted $150 each supplied and fitted at Ian differ in rockingham.
