Ok.....well then here's my question that I've gone around asking....why do people run + so so offset numbers (other than clearing BBK), why would you all run different offsets? I'm going for a track oriented setup and trying to find out which offsets would work best on a 1 inch drop. So far, i've seen hundreds of offsets that hundreds of people are using, yet no clear answer other than "clear BBK, aggressive look, because of the rim, etc", i've even looked it up online and yes it has said its for "clearance" on the inner and outer wells, but still why so many offsets that differ greatly amongst everyone? I know its a noob question, but I just can't seem to understand it, even by looking at everyones setups.

An easy way to look at it is a lip size for clearance. If you look at my wheels they hve no lip and slightly bow outwards which make for more room from the hub to the spokes of your wheels. when looking at rims with a 3 inch lip you are pushing the face of the wheel back making less clearance between the hub and the spokes. The offset will correct this. When you put a lower offset it will push the face out more making more clearance. This is why all wheels are different on how they will look and fit. I hope that helps you under stand a little more. Also to clarify on stock wheels you would need to run some pretty think spacers to make it flush.

Thumbs up for a badass Z!!
Thought I'd share my new set up!
Spring Boot Cut about 3/4" and Rear camber arms and toe bolt. Don't remember what the spec were set when I got it aligned.
Matte Black Enkie RPF1s
18x9.5 +15 F 255/35/ for now
18x10.5 +15 R 305/35 R888s
These Rub. Needed to roll and pull my fenders. Didn't come out as nice as I'd liked but it got the job done. No more tire rub.
Before Rolling and pulling fenders: Spring Compressed
After: Don't have any with the spring compressed but I may have over flared the fenders just a tad because when the spring is compressed I still have a good 1/4" space. Maybe 315s Now I need Coil Overs because the gap became larger after pulling the fenders.

So yea, been looking at a few setups and tossing around alot of ideas but I still cannot grasp the whole "OFFSET" concept. I've researched but I can't seem to quite get it. Pretty much i'm thinking about running 19x9.5 and 19x10.5 +12 all round with 255/35 front and 285/35 rear on stock brembo's. Would this mean I need to roll my fenders in order to obtain such "flushness" but be able to successfully track this setup and re-adjust for daily driving? Or would I have to go with different offsets or tire setups? I'm pretty much looking for function on a track but occasional drives to and from the track. If anyone could share their input, i would appreciate it, it would greatly clear up the confusion i'm dealing with.
They do if they (stock offsets) are on 10.5 or 11" wheels!

Ok I have a question. Do I need to roll the lip? I am getting 19x9.5 +12 front & 19x10.5 +22 rear. I am currently dropped on S-Techs. I am looking to put on a 255/35 front & 285/35 rear, but after reading I am looking at 265/35 & 295/35.

Depends on how wide the 285 or 295 realistically runs and how low you are, but very likely. Our 285/35 Bridgestone RE050A Pole Positions rub slightly on a 19x10.5 +23 wheel, and it's lowered on S-Techs. A slight roll would help, though I have not brought the camber back into spec (which will make it more prone to rubbbing).

Lookin for some advice...
Currently running 18x9 +3 255/35 18x10 +5 285/35
Thinking of EITHER going 18x10.5 x4 (+15 with a 15mm spacer, so will be at 0 offset) and just switching the tires over...but worried 255 will be stretched on a 10.5. I may run it for a bit until I can get new tires but what would be an ideal set up for a square set up like this? I haven't ran square before so I'm not 100% sure...OR 19x9 19x10 with a +7 offset (w/ the spacer) and I have NO clue what tire size would work.
I'm pretty low on bilstiens (pics are in this thread somewhere...let me know if that would help). Just lookin for some guidence...
Again, the offset is with the 15mm spacer included...I don't track the car (unfortunatly) and my rears are rolled. Currently rub slightly on turns but not bad...
Thanks for any advice!

That 255 may work the "poke" with the +0 offset 18x10.5, but that's not my area of expertise.

Thanks Scotts300
Yea I assumed the 255 would be too much stretch for my taste also. But again, until I get new tires I figured I could run it...
I was thinking 285/30 also, but was hoping to sit at 0...but then 265 is stretched. Tough finding the sweet spot of aggressive offsets and fatty tires!! Decisions!
Thanks again man!

but correct me if im wrong...
your not running really low... alot of us want to get as low as possible with fat tires... im even in the process of just saying F* it and just run more negative camber and flip the tires when i get oil changes...lol... just so i can run spacers....
nEWb probably hasnt figured out how to use the forum
