some close ups would be cool! Spacers in the front or rear?

I'm about to try something that I already know is going to be a huge pain.
18x9 +42 square with Nexen Nfera SUR4G (they run very wide) 255/35/18.

18x9 +42 square with Nexen Nfera SUR4G (they run very wide) 255/35/18.
18x8.5 +45 no spacers

Rears rub under compression on metal fender

Fronts rub slightly against plastic fender with high steering input

My ride height is lowered on coilovers so that is certainly affecting my clearance.

According to tire rack you will have a 0.7" overall diameter advantage with the 35 sidewall vs my 40 sidewall. Your tread width is 0.7" wider than I'm running so very curious to see how you make out.

ET42 will not work up front. You will need a 7mm spacer for an effective ET of 35. Be prepared to be able to dial in 2-3* of camber up front. You will also need to roll your rear fenders to avoid needing to run really high rear camber. ET 42 is too low out back (pokes out too much). You really need something like an ET50 wheel and run them with 15mm spacers up front. That would be ideal fitment for a square 9" wheel and 255 tire setup without modifying fenders. 17x9 ET45 rubbed a bit in the rear for me until I took a hammer to the inside lip of the fenders.

Already dialed in -3.3* up front. Already cut the rear fender lip. -2.5* out back currently. I'll run a 7 or 8mm up front.

We'll see how it goes!

Also, this will vary widely by the diameter of your front shocks which is super tough to know without trial and error.

I ran 255 up front but it was real tight, moved to some real wide 245s R-comps up front and 255 in rear.

This is true. I think Ohlins come with a very thick shock body. Most aftermarket coilovers also use springs that are too long and reduce wheel clearance (again Ohlins comes to mind). I needed 7" springs to clear my wheels. ET38 worked up front with stock struts, but now I need ET35 to clear the YCW shocks I am running.

I currently run 255 RS-RRs and 275 Z214 r-comps. This was the only way to balance the car out after widening the front wheelbase. The rear wheelbase was almost 1.5" shorter and the rear would rotate way too easily with a "square" setup that wasn't truly square. I hate running staggered due to cost of tires but that's what it looks like you need to do on these cars to make up for the rear clearance all being inboard. Got to set the car up like a Porsche or a drag car with 315 out back and 255 up front lol Or, hack up the rear fenders and widen the stance.

Yeah. I've committed to a 1M front-end.
