Eh, maybe should rephrase: lack of loss I guess? I'm going for larger wheels which mean larger tires, I did the math and it'll add about 2 pounds of rotational weight altogther if I go for the Michelin pss in 245/45/18 + some Volk Racing te37SL in 18x8.5 so it won't really help honestly, other than the enhanced grip and aesthetics... that I know of anyways.

Why are you looking for 18's over 17's? And yes, looking cool is a valid consideration.

I ask because, as light as an 18x8.5 RPF1 might be, a 17x8 RPF1 will be lighter.

It's my daily driver. I don't plan on tracking it any time soon so I'd rather it simply look great, as 18s look way better than 17s. The reason why despite that I want light is because I want it to look cool, but not take away from the performance. I looked at the RPF1s but 2 of my frs friends already have it.. I want something different than what they want.

Fair enough. I was looking at 18's for a while for just the same reason. I like the PF01's better than the RPF1's by the way.

They both look super sick, I totally respect your choice btw. What made you go with 17s instead of 18s then? Did you decide you wanted to track it? Or did you just want some better performance gains?

I'm still on OEM for the moment, although I did add 20/25mm spacers to look cool. Considering getting the wheels powdercoated glossy bronze.

When I do eventually purchase wheels, I will go with 17's for a few reasons. First, they're cheaper. So are tires. Wheels might not be a wearing item, but tires definitely are. Secondly, the ride is better. More sidewall = more cushion = better ride. My suspension is firm enough already, thank you. Plus there's that little bit of extra forgiveness to keep me from bending a wheel should I hit a pothole or curb or trick-or-treater or something. Lastly, they're less weight. Our cars aren't super powerful to begin with, so any additional weight, rotational weight at that, slows them down. While there are 18's that are pretty freaking light (TWS), most of their mass is still situated further out from the point of rotation than a 17, which is extra inertia you have to overcome with throttle and brake.

These cars look gorgeous on 18's. I'm particularly fond of Shiumai's and Jive Turkey's BRZs, Shiumai with 18x8.5/9.5 staggered, and Jive Turkey with 18x9.5 all around. They really nailed the sizes. It's just not for me.

2lbs is not a big deal despite what the internet leads us to believe. you might be able to feel it but i dont even know if the objective performance difference is going to be measurable. i know they tested that on an autox with a much more weight sensitive car and the heavier wheel actually posted the fastest time. not to say heavier is faster but its all within a margin that is pretty negligible

Bolded part of your comment because this important

The gains will never really be goon enough unless you are TA car....

A potentially helpful data point for you.

I've got PF01 in 18x8.5 with Hankook V12 225/40/18s on them and the wheel + tire weight is exactly the same as the stock tires.

The 225s are slight stretch on the 8.5 wheels, but not too bad. Once these are done my next set will be 245/35 which will probably be a little heavier but not enough to matter.

That's really good to know actually. Makes me comfortable at least that's for sure.

That's actually really good to know. The pf01 in 18x8.5 is like 18, right?
