Ok... Well that's wheel fitment. To address your original question, tire fitment is dependent on lots of factors... Do you want stretched tires, meaty tires? How much negative camber are you going to run? What are your suspension specs? Have you or will you roll your fenders? What kind of duties...
Ok... "Functional" I suppose is a subjective term as well but I'd imagine you're picking up what I'm putting down. Keep up the solid work man... Always admired your tenacity.
Hate is such a strong word brotha... I'm just more of a functional kinda guy... I like my cake and I eat it too, there's no reason it can't be purpose built and look good.
Since you're doing a teardown might as well go big... I say widebody the damn thing then you can actually fit some wide wheels with meaty tires... Is you in or is you in?
You go to any track event and you're almost guaranteed to see some early model Mazda still being utilized for dedicated track duties... There's a reason for that. I feel like Mazda is trying to head in a new direction while forgetting where they came from...
In hindsight Mazda has never...
That grill looks like an Erebuni... Basically some knockoff aero company that I'm not even sure if they're still in business. Hopefully not, the industry could do without.
