What Wheel Spacer Size for Flush Fit Options

[Harold_Fastwaker]

I am trying to flush my "new" set of wheels on my celica. I have a list of measurements I just took and I am unsure if I did this right or not. I am also trying to figure out what tires I need but figure I will wait till I have spacers in to test out how the fitment will be. Then I will figure out what tire to wrap it with.


I have seen a celica running 19x8 +35 on the front and 19x9.5 +35 on the back with a fender roll and slight pull and it fit.


So here is my measurement list:

Currently I have 17x7 +40 with 225/45 R17 tires (all 4 wheels)
I have 1 inch spacing between the inside of my current tire and my strut housing.


I am trying to mount 17x8.5 +56 on the front and 17x9.5 +56 on the rear. From my measuring it seemed almost like I needed close to a 2inch spacer in the rear but that would definitely be alot lower than a +35. I figured I needed a 1 inch spacer in the front.


Anyone able to help me solve this issue.

there is a reason why H & R / eibach don't make spacers with studs already on them, they do make bolt pattern convertion kit like that, because there is no way around it, but a wheel spacer should not be made like that for one simple reason,

when you bolt the spacer to the hub, and then bolt the wheel tio the spacer, you can't see the nuts holding the spacer to the hub and if they were to come lose, you would only know it when is too late.

and just FYI, there is no Track grade studs, Studs are either the proper grade or are junk, so if a wheel spacer's stud is not good for track is also not good for streets.

IF you are really set to go with spacers that big, find a company that makes a spacer with holes and it and long enough studs to go with them, and HUB CENTRIC, don't get those with studs atttached to them, they are not safe, and the bigger the spacer the most pronounce would be the effect of off axis rotation, so make sure you get hub centric spacers. yes a lot of people have them with no issues, just like a lot of people have Ebay racing seats with no issiues either, if we are gonna learn from other cars, let's learn the good stuff.

As for track grade, that is not what I meant. I implied that on my daily driver I have no issues running 2inch spacers. If I was to track the car, I would run proper fitting wheels with an offset that do not need spacers.


I am buying hub centric spacers for the hub side and the wheel side is turned to the proper center bore and hub centric for my new set of wheels. Everything is done to the proper MM, trust me I do not intend on half assing this whole thing.

Spacer bolts are done just like lug nuts. 80-90lbs pressure, there is no reason the bolts should just come undone. Same thing with lugnuts, if they come off, you either have the wrong thread or didnt bother to tighten them properly.
