I don't want to do any fender modification except maybe tucking the inner lip.
And though like 1-1.5 degree negative camber is fine up front, I think I like to keep the rear neutral.

I don't really get the hate toward them. They're lighter than all the other wheels in the price range and come in many mounting options.
The only other alternative I could find are RPF1s which I think look hideous on an FD.

Volks cost as much for 1 wheel as Rotas cost for 4... From what I can see, Rotas are pretty similar spec to the Spirit-R wheels but cheap. And I think the look nice on an FD.
I'd love a set of Volks, but they simply cost too much.

Hey Folks,

I've been trolling the used market for a square set of 18x9.5 +45 for some time. I've come across a good buy on a set of 18x9.5 +40.

Can I get some feedback on fitment with that slight variance beyond what has been discussed as the far limit of front fitment?

I noticed "jonahau" above is running 18x9.5 +38 but with 255s. I was hoping to run Advan Neova AD08R in either 265/35/18 or possibly 285/30/18 as an alternative.

Thank you.

Most 265/35-18 are too tall and will rub the inner fender near where you can see the fender liner under the hood.

Up front +40 offset will fit 265/35-18 with max front camber (~-2.4 depending on ride height) and a fender lip roll. +40 will fit 285/30-18 up front with max front camber and a fender lip roll with mild to moderate pull.

This rubbing would occur only on slammed cars or in a bottoming out scenario? I'm only on RB Sport springs and don't plan on ever going lower than my driveway will allow, which is about right where it is today.

Thank you. Any other tire sizes I should be considering that are friendlier? I guess 255/35/18. Would that help? Would that be too "stretchy"?

The rubbing from too tall a front tire happens anytime you turn the front wheels and yes, can also rub other places when you hit a bump and the tire bottoms before the suspension.

My experience was with 265/35-18 Federal 595 RS-R which are pretty short for 265/35-18 at 25.3" tall. These tires rubbed slightly where I mentioned on the plastic fender liner in the area you can see it in the engine bay when the wheels were turned and in addition my car has the factory mud flaps and the tire also rubbed these when turning. The problem subsided as the tires wore.

265/35-18 range in diameter from 25.2" tall (like Yokohama A048) to 25.5" tall (like Pirelli P-Zero Corsa).

My 295/30-18 are 25" tall and do not rub (in case you are not convinced it is a tire height issue not a tire width issue).

Thank you. But with the 295 (or 285), I would still need to work the front fenders, correct? I'd like to avoid anything drastic.

Any thoughts on 255/35/18? Seems like it checks most boxes, just not sure how the +40 still plays in.

Yes, but you will have to roll the front fender lip under for 265/35-18 on +40 offset as well.

Easier fit with +40 offset.
