Offset with wheel spacers?

Hello Everyone,

I just purchased an 05 92x Aero and so far i have been reconditioning it over the last several months making this into a fun car to drive. Anyway...

My question is that I have these OEM Lexus wheels from my other car that I think could help the aesthetics on the Aero. Some problems I am running into are.

1. Bolt Patterns are not the same
2. Wheel is much bigger than OEM, will it fit? (17" vs 16")
3. Cant find anyone who has done such a thing (probably for good reason)


So for problem 1. I have found that they sell a hubcentric spacer that is 25mm to cover the existing lugs while creating a new lug set in the 5x114.3 that my lexus wheel is. So theoretically, I could get the wheel on the car. (some people hate spacers, I get why, but this isnt really a daily driver, more of a project car. so spare the preaching if you can  tongue)

Now that being said, I have no idea how to calculate the offset and size of the wheel with the spacer. From wheel to wheel, there is like a 13mm difference between the two if the Lexus OEM mounted direct and would work if the patterns were the same. By adding the spacer how do calculate the new size? Do you add the 25mm spacer to the offset or do you subtract? If I subtract, it looks like it will clear the strut assembly but stick out 1.4" from oem. (which could look cool, even if I need to roll fenders, lol)

Saab OEM is 5x100 16/6.5 55mm
Lexus OEM is 5x114.3 17x7 50mm

Spacer is 5x100 to 5x114.3; 25mm thick

Thanks in advance!

Re: Offset with wheel spacers?

Offset calculator

The size fitment won't be a problem. The non-sport wheels were 16x6.5, but the sports were 17x7. I'm currently running 18x8 ET35 wheels as summers, and 17x7.5 ET35 wheels as winters with no spacers and a more correct offset. For a while I was considering putting an 8 or 10mm spacer on, but couldn't justify pulling the hubs to put new bolts in. The OEM wheel offset is 55mm, so my wheels are already +20mm without anything close to a clearance issue. With ET50 17x7 wheels with a 25mm spacer, you'd be working like an ET25 wheel. It'd be close to the lip, and could be a problem if your suspension is low. You would also need to roll your fenders (which you should do regardless).

To play devil's advocate, it might be worth the little bit of extra money to get a set of subie wheels that would fit without having to run a hub-extension spacer. I personally don't think that it'd be worth the headache to run OEM Lexus wheels. I'd probably spend the extra couple bucks and get some proper fitment wheels from the beginning.

Re: Offset with wheel spacers?

Yes, I figure as much, just had these laying around with the option for the Aero.

I am usually a strict modder when it comes to suspension setups. On the Is300 Everything is dialed in perfect. This being my "project/winter" car, I didn't care as much.

I dont care for the tiny 16x6.5 that are on the car now. They are better looking than most OEM wheels, but just doesnt fill the wheel wells that i would like. Thinking with the lexus wheel, they would be much more aggressive.

I was also looking into getting some 17x7 Tracklite wheels since they are pretty cheap to begin with, anyone have any input on these?

Thanks for the help!

Re: Offset with wheel spacers?

Traklite makes some nice wheels, some more aggressive than others. I'd also consider looking at Rota, as they're in a similar price-point and weight class, and can save you some dollars. Something else to consider when looking at wheels is your plan for brakes. If you're intending to snag a pair of STI Brembos (which are accessible and relatively inexpensive at this point), you will need to plan your wheel choice accordingly due to clearance issues. If you are, verify fitment by using a 2004 STI as the car type. (2005+ have the same calipers, but changed from a 5x100 to a 5x114.3 hub design). The reason why I ended up getting rid of my 17in OEM Sport wheels is due to these fitment issues. It ended up being a better decision to sell them, and buy wheels to fit instead of going the spacer route.

Re: Offset with wheel spacers?

Thanks for the advice. I usually dont run spacers on any car. This just seemed like an easy and super cheap way to get bigger wheels on. Easier to spend $120 than $1k on a set of new wheels/tires.

I used to run Rotas on my autocross honda del sol waaaaaaay back in the day, loved them because of how light they were, 16" wheel was something like 14lbs paired with falken azenis, what a setup!

Re: Offset with wheel spacers?

I have 25mm hubcentric spacers and OEM 2015 WRX wheels on my 06 Linear.

I have a 40mm sag block in the rear, and rolled fenders.  I RARELY rub in the rear, and never in the front.

The spacers put the wheels out a bit which is a look I like anyway.
