New guy here. Just got a 2011 speed3 a couple of weeks ago. Today I did the Cobb intake and I would like to do 18x8 or 8.5 but not sure what is the best offset to get. Stock is 52 and I'm thinking 35-40 would look good without rubbing. Mild drop will be next.

Any experience on this?

Thanks

How low are you trying go? Also what size tire are you trying to go? Im running a 18x8.5 +38 with a 225 tire with no rubbing. Mind you I am dropped only an inch. Also Im switching up to a 245 now. Might have to get a lil fender work but to me the wider tires the better. I guess do you like to take spirited runs through a canyon or more for show? Either way you go I can help.

I'm looking at dropping only an inch. Same size tires for now but maybe 245/35's after the stock ones are done. Looks like ET40 is the way to go to be safe?

Thanks

To be perfectly honest, you're asking too open ended of a question. There is no miracle ET that is going to fit perfect and look awesome. It also depends on what tire size your stuffing(or stretching) to fit on your wheel. Wheel width is also going to play a huge factor. You might be able to run an 18x8 on the factory offset of 50 or whatever or you could go with 40 to be more flush. An 18x9 for example might need an offset of at least 45 or lower to keep the wheel/tire off of the strut.

To give a definitive yes/no as to whether the setup in question will fit, we'll need a little more information on the ENTIRE setup you plan to run with. Currently, I'm looking at 18x9ET45 with a 225/40-R18 which is a little stretched but Federal 595's run super wide and look sexy stretched just a little :D

How about 18x8.5's with 225/40 tires? Will 40 or 45 offset be better? By better I mean a little more flush with fender and no rubbing with an 1" drop.

Thanks
Dunston and Warlord (before he upgraded to a speed3) had 18x8.5 with 225/40. Same Tenzo wheels, just different offsets, finishes, and tire brands. I think Conti CSC2 for Warlord and Federal SS595 for Dunston if I remember correctly.

The 225/40 on the 18x8.5 has a very slight stretch to it (some would laugh at that being called "stretch") and is very subtle and clean looking.

Dunston and Warlord were both lowered 1.75" and Dunston had no rubbing with 48 offset. No rolled fenders btw.
On the other hand, Warlord had 42 offset so his stuck out a 1/4" more and he ended up trimming the lip on his rear fender to clear instead of rollling it.

Since you plan to only go down an inch and it won't be slammed, clearance and offset might not be as big of a difference.

However, when you end up with a lot of stuff or people and it get's FORCED lower, then you might have rubbing issues.

One other thing (at least in my opinion) is that overly aggressive fitted wheels on a more stock ride height looks goofy as HELL! Wheels can have poke/flushness on a slammed car and it looks great. Wheels that poke and you can still fit your whole hand in between tire and fender look like a damn 4x4 jacked up high with the wheels sticking out Jeep buggy style :stuart:

If you're only going down an inch, either the 40 or the 45 "should" fit. But the 40 is guaranteed to rub when you load it up. With the 42 offset, the fenders had to be rolled/trimmed. Dunston's 48 offset doesn't rub on the stock fenders and whatnot so 45 offset and being .75" higher than him, you should be fine.

That is a great answer. Thanks.

I'm interested in my wheels sticking out an inch or two and was wondering if you could give me advice
