18x10 ET25 Fitment Question
Hello! I am considering buying some wheels and tires from an M4 racing buddy. He is selling 18 x 10 ET 25 Apex EC-7 with 275/35, RE-71RS tires. I am concerned they might not fit in the rear. I am on stock suspension with 3° camber upfront and 2° camber in the rear. What do you think? Thanks! I did search this already, but couldn’t find a clear answer with the stock suspension.

Calculator says the outer rim will poke out 6.3mm more than my current setup (18x11 +44) which seems like it would contact because my setup is at the limit to my eye.
I run that exact wheel/tire you mention up front, so I can test mount it in the rear and see but uh… not feeling confident. That said, with -2.5* or more of neg camber in the rear maaaybe it’s possible? I know the Team Schirmer E88s are more aggressive than what I run in the rear and they make it work so maybe you just need to want it Lol. |

I just walked out an eye-balled my stock wheels and 265 width winter tread on the back... it would be an extra 15mm over stock... really close.

Yeah, it'll be close. I sometimes run 10.5 ET36 with a 285/35r18 and that looked like it poked at normal ride height (but never rubbed under compression with -2deg camber). 10 ET25 will be another 5mm poke.

10" +25 is at the absolute limit with stock upper arms. And you'll need to run the max camber with slightly stretched tire setup to clear. But it is possible.
If you get adjustable upper arms, you can make it clear no problem. |

I ended up with 18x10 +40 square, and a 15mm spacer up front. Thanks everyone.

Also depends if you're running all seasons vs 200tw track tires. |
