Just picked up a set of 4 rear 370z wheels (18x9 +15) for CHEAP. 2 tires are trashed and 2 are pretty fresh with 245/45/18. I am trying to keep a good enough ratio to not set off the VDC. I would ideally like to put the current 245/45/18's on the rear so I guess that would make the fronts 225/45/18? But I hesitate to stretch 225's over a 9 inch wheel. Would a 235/45/18 or 245/40/18 be within the ratio to not set off VDC?
I'm still figuring out tire sizes/stagger ratios so forgive me if these are dumb questions. I found it difficult to find much information on 18x9 wheels. I am guessing I will need to roll the fenders a bit, especially the fronts but hopefully I wont have to pull them. Currently on stock suspension but will eventually lower.

PS: passing along a PSA: 370z wheels REQUIRE 370z "shank style" lug nuts.

 

• 245/40-18 Front
• 245/45-18 ReaR

Same OEM ~3% VDC ratio

 

Thank you @MicVelo.

 

Should I pull the front fenders and/or roll the rears with this setup?

​​​​Front: 18x9 +15 | 245/40/15
Rear: 18x9 +15 | 245/45/15
Stock height for now. Planning on lowering an inch in the future.

 

no, nothing needed

 

You are no where needing a "fender roll,"

 

$350 for the wheels. $80 to swap TPMS and 2 tires from old set. Ended up selling the old rims/tires for $250. Not my favorite look but can't beat the price.


Last day in LA photo shoot

More lower? .5" drop in rear already.


What if La Mans Sunset?
