But if I was doing a matching set I am going to do 325's in the back like the 1LE and 305's in the front.

Besides the wire harness in the driver side rear I think your good with stock suspension but from what I have read you might have to either use a spacer on the front or grind the suspension down in a specific spot once your add some camber or lower the car.. I could be wrong but I believe it's something along those lines.

There’s not a ton of options like you said. I was planning on the NT555R2 as well. Seems like the most street usable tire out there for high power. It was also recommended by my tuner. I would prefer the 325/305 like the ZLE, however idk if that’s enough to not die on the street lol. I haven’t hear about the spacer/grinding situation. I’ll have to look into that, I hope that’s not the case. Though I am on lowering springs so maybe that clears it?
