Correct.. the one piece (1XJ) is used for front and rear outer. The separates, 1XM is for the rear, and 1XJ for the front.
My guess is that the 1XJ / 1XJ combo in front gives 0º toe and 0º arm sweep in front. The 1XJ / 1XM in the rear gives 2.0º - 2.5º toe in? .. never measured it.
Unlike the TC version that uses that TRF/TB/TA mounts, the XV mounts give us limited suspension angle tuning.
