Wheel Offset Guide, Unsure about proper offset? Look here first. Options

[WannabeGT4]

To reinforce 40mm being doggy doo doo on a lowered car, this is my first Celica on 17x7 et42. 2mm away from the magical number.

OMG I give up...

7" wide should be 30mm offset with a 15mm spacer (effectively 15mm of offset)

You're off by a whole inch that's why it looks so sunk in... Also why I keep re-iterating the importance of taking the width of the rim into consideration when considering offset.

[Con99vert]

I am looking at some 18x7 Konigs with a +45 offset I think I will probably have to get different tires since it has 225/45/18 installed now, but will the rims work? I do not want them sticking out past the fenders. I dont mind putting a small spacer to get them to sit more flush, but I dont want them to rub on anything either.

look at the picture of the black gar with gold wheels a couple posts above yours... yours will be 3mm MORE sunked in than that!

[Con99vert]

It looks like I am going to need some spacers. I am just wondering if the 225/45/18 tires will fit or rub. I would like to lower it too, but worried about rubbing with the larger tires when lowered.

Mount one on the front and then the rear. Best way to see what can possibly rub. Probably need a 5mm spacer though.

I am confused so much info coming from alot of people. I am about to buy some rims. They are pretty expensive so I dont want to get the wrong setup.
My car is lowered 2 inches. The rims I am looking at are 17 inch with a 35 offset and they are 8 inches wide. Will these work without a spacer?

you won't need a spacer, trust me, i have 17x8 +32 and was lowered 2 inches
rubbing will depend on the tire size, with 225/45/17 you will rub in the front when steering wheel is cranked
in the rear you will hit the fender lip if you do sharp turn and have body roll OR hit a big bump
with a 215/45/17 it shouldn't rub ever, but depends on what brand of tire.

I had 17x8 with a 35 offset, lowered on tein s-techs. They fit great without a spacer! only rubbing I ever had was in the front on full-lock steering with my 225/45/17 tires

[mk7celica]

Rims i just got





35 offset 17x8 i am glad they will fit cause I just bought them. I will run a p215 so I dont have to worry about rubbing.
My old rims are 42 offset so these should be closer to the fender?

[Harold_Fastwaker]

Yes they will be closer to flush then what you had.

[BonzaiCelica]

all depends on the width and offset, my 7.5" and 32 offset is still clearing the fender rim. If you are not thinking of dropping the car too low, you can get much wider rims. Local shops will be able to calculate that for you for the celica specifically.

oh ok well i already understood the difference in offsets. I know that +35 offset will fit on the celica just fine even when i decide to buy megan coilovers and drop 2.5-3 inches i should be fine, right TRD....

ok now my question is this when manufactures determine wheel offset. is the center hub closer to the center/middle of the rim or do they make the center hub deep. im not making any sense am I... I mean some rims have that sucked in look and others have a flat look. Lets say that you compare a Advan RCII wheel that has +45 vs +35 offset. Will one rim have that sucked in look over the other, like the rim has a bowl look to it.....

[Harold_Fastwaker]

The lower the offset if the wheel is designed for the sunk/bowl look then it will have it. Some wheels no matter what your offset will maintain the same look. If you want the bowl look then the lower offset will give this.

35 offset is 35 no matter what wheel you buy.

[Promasta]

it is called concave
i have yet to see a deep concave wheel on a 6gc
its an amazing look tho, i would rather have huge concave than a huge lip
really the only 5x100 wheels i have found with huge concave are the 17x9 +30 rota torques
but i don't want to be the first one to do 17x9s in the front
so if i can sell my wheels i have now i'll run staggered, 17x8 +35s in the front (with flat face) and 17x9 +30s in rear (deep concave)
i've seen this look on some s2000s, pretty awesome

[Promasta]

Advan RCIIs are beautiful, but discontinued. There was a used set of 5x100 17x8.5 +45s going for $1200 a couple months ago. They have a bit of concave as seen here.

Lower offset allows for a deeper concave or larger lip, but as Harold said, it depends on the manufacturer, with companies like Work or 5zigen, 7-8" wide will have flat face, 8.5-9" will have semi-concave, 9-9.5" will have deep concave, so it depends more on width, not offset.

Well harold has like 9" or 9.5" at the front, if your worried about anything...

[Promasta]

harold has 8.5
don't think anyone has done 9 front

[Harold_Fastwaker]

I did 9.5 up front as a test run with my rears to see if I liked the lip or not. I plan to change spacers and run et23 offset upfront or possibly et15.

You will rarely see a concave wheel set on a celica since nobody wants to run higher than 8s all around with high offsets.

If I truly gave a crap I would buy a set of TE37s in 9.5 front and 10.5 or 11.5 in the rear for the celica. But I am trying to get a project FC or FD going so I really dont want to keep dumping money in this car. It is my DD so I am trying to not make it look to outrageous for theft purposes. But I am considering a future turbo setup just to make my commute a bit more fun.





I know this is what you are looking for in the end. But as you can see, you need quite a low offset for it.

ya i love those advan rcII i plan on getting those in 16x7 in white or gold. Anybody know how much they weigh??

now my question is this. I know that sti's and evo's have high offset. Why is that. So if we put low offset wheels on our car they will clear our brake calipers right?? what the offset on a gt-4????

[96stgreendemon]

ok question, i have 03 gts rims on an st, what space will make them look flush?

[95CelicaST]

Go find the flush wheel fitment thread. I believe 7th gen GTS wheels are 6.5" wide at +39.

Flush front wheels at 6.5" is 0mm, so you'll need a 39mm spacer.

Rear flushness at 6.5" is -15mm, so you'll need a 54mm spacer.

And good luck with that. Flush 6.5" wheels will look silly. You need more width than that.
