Hey guys,

Just wondering if anyone else is running low offset either with or without spacers.

My rear is +15 and my fronts are +23. thx

what widths are your wheels and factory offsets? what size spacers?
Also what tire sizes? I really like the way you have made more wheels more flush with the fender from the pics I've seen on vipstylecars.com

I'm trying to figure out what size spacers I'm going to need to get my wheels nice and flush
Picking up the 19x9 +42 and 19x10 +43 AME shallens that are for sale on here for my 91 LS400
I'll probably try 5mm front and rear to start with.

Hi,

Thanks alot!

My wheels are 19X8.5 in the front and 19X10 in the rear. Factory offset in the front was +28 and the rear was +35. I added a 5mm spacer in the front and a 20mm spacer in the rear.

I am running 245/35/19 in the front and 275/30/19 in the rear. I could use a smaller tire, but I like the aggressive look of having more beef in the rear as well as more rubber to prevent my tires from poping.

very nice 19x10 +15
I wish I had a bit better offsets

I'm gonna go with 235/35/19 and 265/30/19 toyo t1s. Small stretch but I think it will help a little for fender clearance. I may have to get some of those h&r's as well that your using both front and rear.

Either way keep up the good work on your car man.

Anyone else with low offsets thats wants to post up

Hey Bryan, I have been doing alot of research on spacer options along with a potential customer of mine. I have found that a spacer's size is not in direct correlation to the offset, its actually half.

So if you have a +28 and add a 5mm spacer, you now technically have a +26.5, and in the rear +35 with a 20mm spacer is a 25offset.

Offset is a measure of the wheel width from the centerline of the wheel to the outer rim. When you a add a spacer, its added to the center, so the extra width pushes the entire wheel out, not just from the centerline to the outer edge, thus dividing by 2.

This has been my finding, if another wheel vendor could chime in I'd appreciate the feedback/opinion.

If I ran a smaller tire, I would not have needed fender rolling and pulling. EIther way you can always roll or pull the fender if it doesn't clear.

actually d2. with a spacer whatever mm the spacer is will directly subtract that from the total...........usually most wheel shops most popular spacer is a quarter inch spacer.............an inch is equal to 25.4 mm so therefore a quarter inch spacer is 6.35 mm............ so lets say u start with a +35mm offset wheel and throw a quarter inch spacer on the hub..............technically your offset is now 28.65 mm

actually that's not true. if you add spacer, that's direct effect on the offset. coz' you don't change the center line of the wheel at all.

if you change the width of the rim without changing the center, that's when you change the offset by half.

i have done this before coz' i had the same doubt

rominl

yup i would agree with this, though i usually got lazy and just say 1 inch is 25mm, 1/2 inch is 12mm, and 1/4" is 6mm. sometimes it's easier on the math

D2-AUTOSPORT

Rominl and bluegs, thanks for the input, I was waiting for a few other wheel guys to chime in on this one.

I'm going to continue researching this topic. Perhaps it can be added to the fitment guide.

When you add a 20mm spacer to a +40mm offset wheel the offset is now +20mm.

I usually just use 1 inch = 25mm as well.
I'm looking at getting some h&r spacers for my LS right now.

jtanoyo1

This is quite a misleading question. Do you mean who's put the craziest offset for wheels on their car or who has deviated the most from stock offset on stock fenders?

Coz I can tell you right now, ONETONVIP has probably the absolute CRAZIEST offset on his many rides. He has put on everything from 0 offset to negative offset on his 12" wide wheels on many cars, not including his own wide-fendered cars.

For 2nd GS, I believe no one has ventured any lower than me which has +24 front and back on CL. And even that has stirred a lot of controversy and whatnot.

SoCalSC4

Henry is right on. Adding a spacer is like adding material thickness to the backpad of a wheel.
19x8.5 +40
Add a 25mm spacer
Final offset = 19x8.5 +15

What screws people up is comparing offsets within different wheel widths to each other.
For example, my front wheels are:

20x9.0 +35 has the same "frontspacing" (sits the same relative to the outer fender) as:
20x8.5 +28.65

or, the rear:

20x10.5 +41.35
20x10.0 +35.0
20x9.5 +28.65
20x9.0 +22.3
20x8.5 +15.95
All sit the same at the fender. You're just reducing the 'backspacing,' or distance to the inside.

I am surprised at LexAristo's set-up. On my brother's (Link 13) first-gen, I ran 19x9 +37 245/35-19 (perfect, same as 19x8.5 +31)) and 19x10 +37 285/30-19, and I had to roll the rear fenders. If Lex's numbers are accurate, I have to imagine his wheels stick out past the fenders.

Tire selection plays a big part in whether or not a wheel will rub- his present 275/30-19 Michelin Pilot Sport A/S are every bit as wide as his old 285/30-19 Dunlop SP9000s!!

thakns for the explanation bob, that's very detailed explanation

and i think it has to do with the camber too, i bet the camber on lex's car is very negative?

D2-AUTOSPORT

Bob, great explanation, the backspacing is a topic that I always keep in mind, but hopefully this will help potential customers understand.

Although wheel fitment seems to be a pretty simple thing, there are SOOO many variables!!! The amount of, "how come I can't run this, since my buddy with a G35 can" type questions I get are phenomenal! LOL

The good thing about this forum is different types of modders introduce people to different facets of wheel fitment. Like Jtanoyo's thread made offsets and bolt patterns a prevalent topic, same for chuckb and the hub-centric thing, or junction with the stretching, etc etc.
