We all know to use spacers to decrease wheel offset and get the wheels to stick out a little more. But how about in reverse. Some of the wheels I've looked at a little too aggressive for my taste and searched the web to try to find a solution. Anybody heard of milling a few mm's off the back of the wheel to increase the offset? Unsafe or safe? I'm talking about 5 mm max. What do you all think?

 

It really depends. The hub area has to be thick enough to prevent cracking/breaking under severe load, especially where the lug nuts go.

The problem though is the more you mil on the hub-facing section, the thinner the portion that the lug nuts are holding on to.

Personally, i wouldn't do or recommend it. Get the proper sized/machined wheels if possible.

 

You can contact Weldcraft Wheels Wheel Widening Wheel Repairs Wheel Restoration to see if they can help you.

 

Some manufacturers manufacture the wheel like that on purpose to allow for a few mm's room for milling. Eric@GetYourWheels offered to trim my wheel mount down a few mm's when I thought it was too aggressive. I opted not to however.

What width/offsets are you going for?

 

if its a multi-piece wheel you can get a new barrel, or if its 2 piece welded you can have them remove the face and have them change it to the offset you want.

 

I have heard of people milling a couple mm off but 5mm may be a stretch.

 

Thanks for the replies. I figured it would be mixed bag and really depends on the amount of material between the back plate and the lug seats. If only the sedans didn't have such high offsets.

Sam, I ideally want a 8.5 +35 in the front and 9.5 +45 in the rear for my sedan. But no more than a 9.5 +40. Very conservative I know, but I'm not dropped, and if/when I do drop it, I want to run as little camber as possible (-1* to -1.5* in the rear). And I don't mind having the wheels tucked a little bit. Some of the wheels I like are 19x9.5 +35 in the rear, just too aggressive for me. Looks like I should just save up and buy some custom wheels to get the offsets I want.

 

I have 9.5 +38 all around, with the camber now back in spec (since last week) it sticks out ever so slightly, an extra 3mm probably won't hurt. The car is conservatively dropped on BC's.

 

Thanks, your car is kinda how I came up with wanting no more than a 9.5 +40 cause I'm thinking 275 in the rear with a 9.5 instead of 255's like you have. Or go square 8.5 +35 with 245 tires? Just trying to figure it all out so I can set aside a budget to start saving towards.

 

I am leaning towards your thinking. I have some vertini wheels. I was afraid they were the wrong offsets when I test fit them. Actually called Eric and sent him pics of my test fit. He assured me they would fit better when the car was lowered. I have since lowered the car. Although it looks great. I would rather the rim/tire did not protrude beyond the body. I still get slight rub on rough surfaces on the outermost region of sidewall. I am contemplating with getting diff offsets in the same wheel.

 

I'd suggest against doing that. That area of the wheel takes a lot of stress. Start shaving material away from that area and you'll compromise the core of the wheel.

 

With in-spec camber, i think 275s will be tricky. Here are photos of mine looking from the top down with the camera offset to the outside just a bit to give you a point of reference as to where the fender ends and how much the tire/wheel extends out.

This is of the rear, point of view is of me right behind the taillights facing towards the front of the car.


Here's the front, point of view is of me in front of the headlights, facing towards the back of the car.



Again, this is with these camber settings and 18x9.5+38 w/ 255/45s (soon to be 265/40s). I may dial in a bit more camber for the new tires, as of now i'm just trying to neutralize the uneven wear i've had on the tires after the last pre-camber kit alignment.

 

I hate to bring a thread back from the dead, but I've searched and searched and can't seem to find an answer to my particular question.

I have a 2010 G37x with 225/50/18 all around. IIRC, the offset is +43 in the front and +45 in the rear. I'm coming from the RWD world and have an RX-7 as my garage queen(bought the G as my daily), so this whole "3%" thing is new to me. In my search for wheels, I believe I am going to go with Enkei Raijin 19's, either 8" +40 or 8.5" +35. The tires would be 245/40/19 to stay within the 3%. Here's my question that I'm REALLY hoping somebody can help me with:

I'm looking for a setup that's as flush with the edge of the fender as possible. I would rather have the wheel stick *slightly* out than any amount in, but I don't want anything to look goofy. I'm not sure if it's just that 2mm difference in offset, but it looks like the rears stick in a lot more than the fronts. Based upon my two wheel options, what type of setup would you recommend? 8" +40 all around, 8.5" +35 all around, or 8" +40 in front with 8.5" +35 in rear?

Thank you very much for your help!

 

Coupe or Sedan?


G37 coupe AWD OEM is 18x8 +43 and aren't staggered.

Out of the choices you provided the 19x8.5 +35 will push the wheel out the most, 14mm more than OEM to be exact .

 

Coupe, my apologies.

Now that 14mm, will that push the tire out past the front/rear fender? And based upon my original question, which of my 3 options would you recommend?
