I've done my fair share of searching through this forum for owner RPF1 owners, but most posts from several years ago. Maybe some can chime in with a picture of their SC300/RPF1 setups.

There's one setup on here that I'm in love with from user buddapoi, but he won't respond. I'm wondering if he's running spacers.
F 18x9 35mm with 225/40/zr18
R 18x10 38mm with 245/40/zr18

Due to the offset of the wheels I'm thinking maybe 15mm spacers all around? What do you guys think?

 

I've got 17x9 +24 in back and they fit nearly identical as that picture. If those are 18x10 +38, they would be about half an inch out (13mm) based on extra rim width, and 14mm in based on offset. So, I'm gonna say they don't need a spacer to fit like that.

I have RPF1s, but not on the SC. That light of a wheel makes me a bit nervous on a heavy car, especially when going +2 tire size and having little sidewall left to protect it.

 

maybe do a little more searching/browsing in the wheel fitment thread. with that pic i dont believe spacers are used. here is another thread with rpf1 fitment:

I went with 18x10.5 +15 all around. No regrets.

 

I did go through that thread prior to posting this thread. If you notice in my first post I mentioned I liked a 'specific' user's offset. All the offsets shown in that thread didn't appeal to me except for maybe...just maybe MrFairLady's. I also messaged him with no response.

 

I was puzzled for the longest time how people claimed such and such wheel fits with only fender rolling, when my test fits with less aggressive specs clearly did not. I finally realized what your pictures sort of show: They don't fit in the classical sense.

As far as I'm concerned, anything that requires a stretched tire and camber to clear the fender does not fit. The wheel is beyond the fender... I realize my tastes are in the minority on that, but it sure would be nice if people qualified their recommendations with that rather important detail.

 

10.5 in the front is aggressive. There's this guy named Lonnie at the Supra Store that had a rpf1 setup with no stretch at all. Ive emailed them to find out, and will post his setup for others on here.

 

what size are your tires?

 

i think they are 225/40.

i actually have a 5mm spacer in the rear too.

 

I don't think the car in the first post is running spacers in the rear. If the front has a spacer its 5 or 10mm at most, but I don't think it has a spacer in the front either. Are you sure those tires are the correct sizes? a 225 on a 9 should have a minor stretch and a 245 on a 10 will have a noticeable stretch.

 

The RPF1 are such a nice looking wheel and extremely popular. We normally have specials on these all the time if anyone is interested.
For the SC430, a 5 mm spacer would be just enough IMO.

 

225/40 is stretched... if I can't fit a 295 on it then it isn't going anywhere near my ride so it does help to say fit with stretched tires etc.. but it is obvious from the pictures of course.

 

I've got a set of Supra TT's with 225 winter tires, and that's stretch city in the back. They're smiling at the thought of an extra 70mm.

I would say it's 50/50. Side shots and a lot of the angled shots make it look like they fit within the fender, because the tire being inside the vertical line makes it deceptive. It takes an almost straight on shot to see that the rim is jutting out. Then, of course, there's all the posts saying something fits but not having accompanying photos.

 

i'm 99% sure the original picture has spacers, there's no way 30-something offsets are that flush even for stock arms and whatnot.

18x9.5 +15 rear
and this is back when I ran almost 0 camber in the rear

 

Those 18X10.5s actually don't fit. Don't mislead people.
