stance gang couldn’t have enough alignment issues with their FR-Ss, gotta do the GRC next :rolleyes:
Happens with every sporty car and plenty of non-sporty ones. Might as well get ready to see it happen to the Rolla.

Not a fan of those wheels specifically, along with them being 19's which IMO are too big for the GRC. 18x9.5, 18x10, even possibly 18x10.5 will be the best sizes.
This guy in the FB group claims 18x10.5 fits easily. IDK about all that, maybe with some stretched 245's or something...

It's worth noting that adding more width with super grippy tires will add more strain on the suspension. If I recall, it might have had an affect on GR Yaris diff temperatures. So over gripping the GR Corolla may not be advised if it's not needed or if there aren't supporting mods.

Exactly! Hence different decisions were made with the Morizo Edition which wears the Sport Cup 2 tires, and it rides with different ingredients inside that coilover.

Yup! This is exactly why you can set a car up to behave anyway you want with the right spring rates, tires, alignment, etc. Decrease grip in the rear and you can definitely get some oversteer. The stock car is just what Toyota thought would be approachable to most.

I can't wait to tweak and tune mine.

I like to keep things honest and real with myself.

Wheels and fitment for me are purely first aesthetic. Meaty tire stance is what I need.

Over gripping as @KanmuriDavid mentioned is a very good point and one to understand if you are tracking, drag racing the car. Maybe even daily it as over time additional strain makes components fail prematurely or more routine maintenance is needed.

Oh for sure, but I was referring to street wheel setup. Most serious track guys who happen to DD their "track" car will have a dedicated set of track wheels and tires to go along with their street setup. Guess I should have been more specific.

Probably less of a concern for street use, especially if you use average tires, but perhaps a lower offset wheel can achieve the same thing without added width. Maybe changing the diff fluid more often.

Funny thing. I am trying to fit 17s over those brakes when I get mine. I need the extra meat on the sidewall for all those wonderful PA potholes. Besides, my wheels weight 17lbs at 17 inches which will likely be lighter than stock 18s. These same wheels did fit over the Lexus GS350 F Sport front brakes which on paper has very similar size to the GRC fronts.

If you get a performance pack/circuit edition, you probably won't be able to fit 17s. There wasn't much clearance on the stock 18" wheels when I saw the car a couple months ago.
