I know I need some adjustment but really satisfied with the result... I have some xxr 531 hyper silver with 18x8.5 (+35) on front and 18x9.5 (+35) on the rear with 225-40-18 on front and 255-40-18 on the rear

Not sure what you need adjusted, that's pretty decent fitment. Usually people go a bit too wide with XXR's and they don't have the offset right. Yours seem to tuck in quite well.

that's true but maybe I should go for 235 - 40 -18 on the front and 265 - 40 -18 on the back... no problem at all really tight fit but is working pretty well especially on these streets of PR... I should go to same style only a chrome one for auto show...

Can you guys help me size wheels for my supra? I don't want to roll fenders if possible and I think I want to stick with 18's all around (unless you can convince me to go 17's). I'm looking to get Cosmis Racing XT 206-Rs.

https://www.cosmisusa.com/product/xt-206r-2/

Sizes available:

17×8 +30mm 5×100 & 5×114.3 CB: 73.1

17×9 +5mm 5×114.3 CB: 73.1

18×9 +33mm 5×100 CB: 73.1

18×9 +33mm 5×114.3 CB: 73.1

18X9.5 +10MM 5X114.3 CB: 73.1

Thanks for the sizing help in advance.

This is my new wheel setup. You can judge the offset by the pics...

RTX Mystique Machined/Black ET38 (offset) | HB 73.1 | 18 x 8.0 | 5x114.3 Front RIMS
Falken FK-453 235/40 FRONT
RTX Mystique Machined/Black ET42 (offset) | HB 73.1 | 18 x 890 | 5x114.3 Rear RIMS
Falken FK-453 265/35R18 REAR

I found that the Falken has a rounded sidewall which allows for the 265 on a 9" rim. Any wider (275's) and I get pretty tight to the inside of the wheel area, so I opted to live with the 265's.
No rub, no roll, no pull. Fits pretty snug. The 235's on the front are wide enough to make the car ride road ridges (which is a bit uncomfortable) but gives me plenty of traction... (for street driving)

Car has ST Swaybars and HSD Coilovers with about a 1" drop (looks a bit more). This is a bit too low for my roads.. I tap with my front bumper.

(excuse the dust... no chance to detail the car ... lol.)

Agreed, the 18x9 +33 with a 255/35R18 tire will put you even with the outer quarter panel. (maybe just slightly past, but not visually). You will probably only rub on really big bumps. My old Work wheels were a +42 offset with 255's and the quarter panel lip would just touch the sidewall top portion if I hit a big dip at about 140 kph. Other than that, they never touched. (mind you... my suspension is a bit stiff)

Tires have different "shoulders" so on a rounded shoulder, you probably would never have an issue. My tires were sharp shouldered. Don't forget the hub centric rings though.

Fitment for NTO3+M's please?

Link to sizes: http://enkei.com/wp-content/uploads/2015/01/NT03-m.pdf

Sizes:

18x8.5 +38
18x9.5 +27
18x9.5 + 40

I'm running Eibach lowering springs and Koni Yellows set to firm.

I'd like them to look as much like Rodel's as possible without any fender rolling etc.

of those sizes, 18x9.5+27 is your best bet. that wheel also comes in a 18x10.5+30 size, but you'll have to roll the fenders for that one.

Ok, help.

I've read and read and still don't know what I want. I like the RPF1s, I think. Anyone know if they'll clear the AZP Wilwood brake kit? Also, I'm on ST springs (1.75" drop if memory serves, illumina II shocks)

I'm currently running some old Koenig Villains (17x8 front and 17x9 rear) and I had to get a 5mm spacer in the front to clear my brakes. I ran out of talent a while back and banged up the wheels pretty good, requiring some welding to repair one. They've never balanced right since, and I'm ready to replace them. I think I want to go to 18s, and I know I want more than my current 255 tire out back. I'm not opposed to rolling/pulling the fenders a bit, but would like to avoid a stretched tire or silly camber. The car needs to perform, not just look good. Can I run 18x10.5 15mm offset rears and 18x9.5 15mm fronts and make it actually work?

Advice is appreciated. Here's what I'm working with:

The thing about rubber is more of a Why? I have 265's on 18" rims in the rear with a +42 offset and they don't stick out. Plenty of room for BBK if I want. However, this means a stiff sidewall, so not the best for off the line take off because no flex. My wheels don't poke out but if I was at a 1.75" drop I would probably rub slightly on big bumps.

I actually just raised my car 1/2" because it was rubbing on the front bumper too much coming out of parking lots. Funny how the ride actually is now a lot more comfortable.

So to run 10.5" rims your going to poke out a fair bit. My 9" with the 265's give me about a fingers width clearance on the inside. I've seen 10.5 on a super clean Supra and the only ting I could think was ... why?

Talking to the owner, it was solely because he didn't realize how they would poke out.

So, aesthetically wide tires look meaty and cool, but I like mine to perform their function without damaging the car.
I think my total drop now is about 1".

My approach is to get as much wheel width and tire as possible on the road, as well as to accommodate a BBK. Eventually, I will change the 5 Zigen wheels that came with the car, but my set-up includes 18 x 8.5 +38 on Michelin 245/40/18 PSS, front, 18 x 9.5 +38 on 285/35/18 PSS, Tein Street Flex coilovers and the AZP 6-piston/14.25-inch, 4-piston/12.88-inch BBK.

No rolling or pulling fenders involved so far but, just recently, and after about 2,000 miles of driving, my front tires have hooked the inner lip on both sides going into very steep driveways. No damage, fortunately, but if I can find an expert fender roller that can deal with 26-year old paint, I will probably have them rolled. If not, I will probably raise the front end just a tad, as the car has my preferred mild rake and, hopefully, fix the problem that way.

Anyway, the extra meat on the road, courtesy of Michelin, ST sway bars, Tein Street Flex coilovers, the AZP BBK and corner balancing has made this the best handling MKIII I've ever driven. As these cars really benefit from wider wheels and tires, correct widths and offsets are critical to extracting all they have to offer.
