Tire fitment issues in the rear

These are Wedssport TC105N 17x9 ET35 with Yokohama AD08R 245/40R17 at stock ride height. It seems like there wouldn't be any rubbing at maximum compression, but the poke looks terrible.

The last photo is the clearance for the front shock.

How close is it on the inside? Enough room that maybe ET45s (17x9) could fit?

If that measurement to the front shock perch is accurate enough, you'd have about 0.20" of clearance (10mm closer = 0.394" closer). Adding camber might close the gap? I don't have a strong grasp of suspension geometry.

18x8.5 +45 Wedsport SA77R with the oem 215/45 Michelin PS4. OEM suspension/alignment.

Do you have any good photos with the wheels facing the sun? The fit looks good, I'd just like to see the design more clearly.

Looking back through the thread. Coilovers are required. If still on stock struts you'll need a spacer

I'm going to get some better shots this weekend and will share

Keen to see more pics. I think your size and offset is about perfect.

I have arc-8 17x9 et 45 with some skinny Sumitomo P03 245/40/17 tires and they fit on stock suspension with no clearance issues.

Pretty sure they are not 45.

you're right, they're ET42.

That's what I get for replying before coffee.

Thanks thats great info. Are you on stock suspension?

I was for a little bit and I had no rubbing, even over bumps and rough pavement, but as pointed out above I misquoted the specs of my wheels. They're ET42, not ET45. You can run a 3mm spacer to bump them out though and the effect should be the same. 3mm is about the most I would run with the stock wheel studs, as that would only give about 7 turns of engagement on the stud.

This is anecdotal evidence, but I ran a 1st gen hyperblue for 20,000 miles on 17x9 ET45 Enkei RPF1 wheels with a 3mm spacer up front and had no rubbing issues either.

So I'm thinking this is the setup I want to go with for stock suspension no chamber adjustment square setup.
18x8.5 +35mm
Michelin Pilot Sport 4 S 245/35ZR18
will this work? I used will they fit and to my eyes it looks like it should fit but I wanted some unbiased opinions on it.

When I was buying wheels and tires from Tirerack, my salesperson recommended that if I did an 8.5 inch wide wheel with 245/35-18 tires, that I should do a +45mm offset wheel.

hmmmm that's interesting was that for the all around or just front or rear? I got my combo from fitment industries I haven't bought them yet but they said it was within safe margins. What was the reasoning the salesperson gave for the +45mm? Would a 10mm hub centric spacer work on it? would changing it to 40r change that? im not questioning the sales person just trying to understand as i dont know much about wheel fitment.
