17x9 ET45 RPF1 fitment on IS350
Hi
I found a set of RPF1 in 17x9 ET45 locally.
Will they fit over the front brake of an IS350?
If I put 255/40/17 on them, will there be rubbing concern? ( I am on tein s-tech lowering spring)
Thanks

Only way to know for sure is to test fit the rim to see if it would clear the caliper...but 255/40 tire definitely wouldn't go on the front.

As mentioned in the thread, offset is 45mm (thus ET45)
regarding tire size, I know sportskid run 255/35/18 on his front without rubbing, and 255/40/17 should not be larger?

If it does clear the caliper its going to be REALLY close. I put a 17x9 et48 PF01 on my car to check, it rubbed on the caliper, and I'm guessing the RPF1 has a little less clearance than the PF01 I tried. My guess is you are going to need a 5-10mm spacer to make it clear, and I'm also guessing you'll need to roll the fender for a 255-40 to fit without rubbing.
If the wheels are local, see if you can do a fit check. Then please report back; someday I want to swap my back 17x9 et35s to the front of my car.

I think you're going to have rubbing issues with a 45 offset but I can't say for certain. As WylieKylie suggested, your best bet is to get a 5-10mm spacer to add additional clearance.

It may roll straight ok , but any turns with speed or slight bumps I think it will scrape.
The stock tire is 225/40..going 255 is a bit wider...like they say you may have to roll and fender pull, and still would have minor scraping I believe...but never know till its on, and under real life driving situations...

Do yourself a favor and do not buy 17" wheels. They will look soooooooooooo tiny. And quite honestly look a little silly. Are your intentions to use this as winter wheels?

Thanks everyone for the great information.
I am currently running 17" stock for winter and 19" vossen for summer
I am looking to get 17" lightweight rim to reduce the unsprung mass and also tire cost (255/40/17 is hell lot cheaper than 19 inch option for summer tire)
so my question is...
1. If the wheel have high offet (40-50mm range), where does the tire want to rub at locking turn?
2. If the wheel have lower offset (30-35mm range), where does the tire want to rub at locking turn?
Just trying to get idea on what to look when I test fit them on.
p.s. I want to avoid rolling if possible, and I do have plan to replace stock shock with coilover when the shock starts leaking in the future.

2. I'm no expert here but I think the fender is the issue with lower offset. This may also change depending on if you are lowered.

Many 17" wheels work fine on the IS350, including the OEM wheels (which some IS350s came with from the factory). I run 17" OEM wheels in the winter and 17" PF01s in the summer. For all those that think 17" wheels look bad, I have a really hard time seeing the wheels when I'm driving the car, and 17" wheels perform better.
