It partly depends on your wheel offset. And you state you are maxed out on camber, what is your camber #? What tire are you currently running?

I just did 325/30-19 Goodyear 3R square on my '14 1LE with the Z's DSSV struts. I run 20mm offset front wheels and used a 5mm spacer, effectively making it a 15mm offset.

But I also have Vorshlag camber plates at full in. As long as you have about .250" clearance between the tire and the strut you will be good. You may need a small spacer.

Take a look at your current clearance and make the call from that. If you are already near .250" clearance then you'll have to run a spacer.
