Need Major Advise 18x8.5 + 40 offset

[Composite]

I am looking into purchasing some wheels, I already tried the fitment calculator but I had no success trying to find the fitment I am posting about. The rims are 18x8.5 with a + 40 offset . Lug Pattern is 5x114 and the tires would be 225/40/18 . Does anyone know if this will fit correctly? Also I plan on getting a Sportline 1.4" drop in the future with these rims.

Thank you in advance.

To fit 5x114 you'll need an adapter. A number of vendors produce them; it's basically a bolt-on 15mm spacer with new studs in the larger size. It'll change your effective offset from +40 to +25, so keep that in mind when you're looking at the wheel fitment guide.

The linked thread says that an 18x8.5 +25 will stick out a lot in the front and a little in back. That may not be your best choice in wheels.

So I guess these are not a good fit? I am still new to rim sizing so wouldnt +25 offset pop out less than +40?

A lower offset will poke out more. 18x8.5 +40 would be a great wheel size for you if you didn't need the 5x114.3 adapter. That's what kills it. Is it possible to find those wheels in a 5x100?

My front is a 18x8.5 +42 and it fits great, looks really good. +40 would be good too.


find the wheel in 5x100 or find another wheel that has a similar look. Which wheel are you looking at?

Thank you people for the advise, I guess I will have to wait until I find another deal on rims due to the lug pattern. I found these used locally online and was going to jump on the buy but the lug pattern will not be a direct fit so I will wait for something else to come around.

Thank you to all ; )

18x8.5 +40 will work good on a stock FRS body but since the lug pattern is 5x114.3 you'll have to run a 15mm adapter which will result in +25 offset.


We are carrying some wheels that are 5x100 and the fitment is 18x9.5 +38 which works perfect on a stock FRS/BRZ body will also fit on stock or lowered FRS/BRZ suspension.

Just did some math with that calculator and it looks like your 18x8.5 +40 with a 15mm adapter (actual offset will be 18x8.5 +25) will sit in the same outer position as the Ambit Wheel RS18 18x9.5 +38 we carry.

Yeah, it's backwards to what we would normally think when we first encounter this stuff. Bottom line is what gramicci said:

Smaller Offset Value (including negative numbers) = Wheel Further Away from the Hub / Sticks Out More
