Tire fitment issues in the rear
So apparently Subaru and Toyota changed the shape of the rear quarter panels in such a way that some of the tire/wheel combos common on 1st gen cars no longer fit.
@trippinbillies40 has posted photos of 255/40R17 tire poking out of the fender on 17x9 et45 wheels. You read that right, poking on 45 offset wheels, meaning the typical 35–40 range wheels will poke even more. He's still on stock RLCAs at ~-2.0º camber in the rear after lowering, but by my estimation adding 0.5...1.0º of camber in the rear will only give you a couple of millimeters of extra room. It looks like it's going to be a challenge to fit big tires on identical wheels front and back. I anticipate some people will end up doing some cutting and wide body / fender flares in the rear to keep using the tires/wheels they used on 1st gens. Some people might want to stick to 215 or 225 tires for a while until a more appropriate solution is found. What can a proper solution be? Shorter rear upper control arms? Fender rolling? Aftermarket hubs? Subaru and Toyota, why would you do that to us?.. We'd be better off with the front suspension optimized for ~40 offset wheels, rather than the rear geometry optimized for 48 offset wheels :mad0260: I'll let @trippinbillies40 and @CSG Mike provide more details, but wanted to start this topic in case someone is about to put down an order on a 2022 car, or take a delivery, or something; and this information is critical to their decision. |
How much poke are we talking? If the tire is significantly stretched 8.5 ET45 could be a decent alternative for running 245-255 tires.

Is it a poking only issue or rubbing issue?

This one from Japan shows the damage to the rear

That sounds like 245/40/R17 on APEX ARC8 ET42 will not fit in the rear as well.

Really would like to hear more about this. Hopefully some light modifying will allow go to wheel sizes to fit.

Look like a lot of Gen 1 wheels will be on sale. Sucks if It turns out that square setup doesn’t work. I am OK if it just solved with rolled fenders

Skip the 17's and 18's, grab up some nice 16's and life will be good:party0030:

The rear looks pretty low to my taste, so I thought the owner just didn't set up the bump travel correctly (see video below), and the tires were hitting metal first before the bump stops were fully squished. Well, it might still be a valid explanation, or at least a partial solution? If only there was one language used everywhere and Japanese folks shared their findings on this forum, that'd be great for everyone... :( https://www.youtube.com/watch?v=oocnORiEXfw |
