The setup is a bit heavier than the stock setup I'm sure but the car grips and drives much better now between that no the alignment changes.

All I need now is more power lol

You're lightweight 18s need to be lighter to compensate for the larger diameter, and even lighter to reduce rotational inertia.

Someone might correct me but:

I = m × d²

yeah it would make a difference if there were no tires involved. wider wheel, wider tire. take weight off wheel, add weight with tire. offset of the wheel matters too along with the width, like someone pointed out.

I kinda understand I suppose. but would an extra inch really matter?

Why does offset matter? I'm curious and uneducated so please help me understand.

And that's true, how much do the stock tires weigh anyways?

lol. I wouldn't worry about the car losing it's handling characteristics. With that being said, much more grip over stock.

Acceleration will suffer a bit (trivially, really) with such a wide wheel (and heavier tire) but you already mentioned a much more conservative wheel size above.

With that being said, going from the slightly heavier Enkei NT03's I had in the same size, to the TE37's, the weight difference was definitely noticeable in my opinion.

oh and shameless plug, I'm also selling my set.

How much power does your car have? If you like the "tail-happynesz" of the car, you will not be happy with adding that much extra width, weight and grip to the rear.. The rims may be 2 whole pounds lighter /s, but the rubber to properly fit on them will make this set up weigh more than stock.

Offset is basically what determines how far from the hub your rim will sit. Higher offsets will pull the rim into the car, lower offsets will push it out from beyond the wheel well.

I believe the stock offset is around +48? I forget. and that is on a 17x7 wheel. So that is why the wheels appear sunken inside of the wheel well.

Nooo, that's not what I meant, I know what wheel offset is (thank you anyways though!), what I meant is why does wheel offset matter for how a wheel feels while driving.

Oops, sorry haha, keyboard is messing me up. My car is stock minus a tomei type80r, a lightened crank shaft pulley, and a trd performance air filter. It's not turboed by any means but if I'm throwing down the throttle around a turn I can feel the rear wheels take the car. I don't really wanna get rid of that to be honest. I realize adding more rubber will add to the weight, do you think I just get a tire that isn't stupid grippy so I can still have a bit of tail-happy?

I keep hearing about the Michelin pss! I went to Costco and the dude recommended the AS3s over the pss and upon coming to the forum a lot of people have them and like them, what're your thoughts? it's good to know you still feel the spin! Those wheels you're selling are mint, I just wish they were 18x8.5!

I would really recommend the AS3 as well.

Too Grippy? Is that even possible? I have MPSS 245/40/17s. I have a stock engine, and I can still spin em. I have an auto too!
