XXR 527 18x8.75 or Enkei RPF1 19x9.0, i know it's a weight different but what it's the advantage and disadvantage

Just do a search about unsprung weight and it'll help you a lot. If you just want looks the xxr will be fine.

Are you looking at two sets of used wheels? Rpf1's are way better than xxr's as far as strength and weight go. I personally wouldn't run 19's. Your question can only be answered if you compared both wheels without a size difference mixed into the equation. The clear winner are the rpf1's.

19's will be to tied, i would go with a 18x9 rpf1

Your English is a little off.

crisdiarata

Why did you ask about them then?

There is no real benefit to running a 19" wheel. I would definitely run an 18" wheel in your specific width you're looking for.

And remember lighter doesn't ways mean better. There's other factors that you have to take into account, like deflection under load

crisdiarata

Yeah i believe 18 are just bigger enough, wondering if will be ok with RPF1 18x8.5 30 or 40 inset? looking to get 255/40 or 35 tires, also i don't understand why enkie web page says than 18x8.5 weights 18.95lbs and 18x9.5 18x90 35inset weights 17.10lbs doesn't make sense.

crisdiarata

What you mean with deflection under?

I hear than lighter wheel help you for a drag, but heavier will be better for high speed, i don't know if that right

The offset must play into the difference in weights on those two different wheel sizes. There would definitely be more material on a larger offset wheel. Or at least it makes sense to me that way.

And you should be just fine running a +30 offset wheel

crisdiarata

I just had tell than my FN01R-C 5zigen weights 18lbs so i wont make sense changed to enkei's, it's other brand lightest than this wheels at the same price?

A heavier wheel would help you at high speed stability just because of the inertia of the wheel, but basically a lighter wheel is always better in the sense.

He means that a wheel can be light, but not necessary stiff, meaning during lateral loading (high G turning) the wheel will deflect and bend, and it will change how the tire will stick to the road and steering controls. Stiffer wheels are better.

I guarantee that'd be case, highly doubt the website is incorrect.
Enkei makes some of the worlds best wheels along with BBS hands down... they are some of the worlds largest wheel manufacturers for aftermarket, OEM, and race.
