Wheel offset questions
« on: January 16, 2017, 02:07:25 PM »
I'm looking at finally getting some new wheels to replace my stockers.  I need new tires in the spring so I thought why not.  I have found a wheel that I like but still unsure on the offsets that will work for our cars.  I have a 2012 WRX, so I know that its 5x100, 17x8, with a +53 offset.  Here is the wheel I've been eyeing for a while now...

17x8  +35 offset
17x9  +35 offset
18x8.5 +33 offset
18x9.5 +38 offset

Now its got a lot of choices for sizes and offsets.  I'm fine with going up to an 18", or a wider tire if need be.  My biggest concern is that they don't rub, I would rather not roll my fenders.  FYI, I'm on stock suspension.  I also want them to sit right and not wear out the bearings prematurely.  Any help or a point me in the right direction to someplace that I can find my answers would be awesome.

These are good tools to help visualize and find the limits:

Enhanced bearing wear is going to come with the territory, though isn't a huge deal unless you've got tons of mechanical grip. Avoid sticky tires and lateral g's.

Is there a way to avoid or upgrade parts of the car to reduce or eliminate bearing wear when going wider?  Or is it just something you have to expect?

You could covert the hubs to STi ones to get the beefier bearings... but then you're talking a fair bit of money for something that's not necessarily going to be an issue.  Compared to the cost of slightly more frequent bearing replacements, it'd take some time to make up the difference.

So the worst thing you could do would be: full slick race tires on the widest setup you can run, in the dry, hot tires, and something like AutoX with fast and severe direction changes.

The opposite of setup of: running the smallest width that still appeals to you, running not-sticky tires like all-seasons, and driving very gently which is going to avoid wear the most.

I was actually asking about my WRX STI... which would hopefully still have STI bearings!  I'm asking because I didn't like the idea of Spacers for long periods of time and decided that a wheel with a slightly wider offset would be better.  Like... these Method MR501 wheels I've been eyeing for like a year now.
