Yeah but they are kind of heavy though. I have a few friends that had them and they weighed more then any other rims that I had to take off the truck at a track day. This is with tire on though. The weight isn't extreme though.

**EDIT- I take it back did some research and they are around 20 lbs each.. I guess they were just more then the other rims that I was lifting that day.

yo tim... so far in the rear, where i currently have my rubbing issues, going lower should make more problems with rubbing on the fender. the suspension articulation makes it look like the wheel moves out as it compresses, which will give me more room between the tire and strut. ill definitly have to look into rolling (maybe even pulling) when i do a suspension.

The wheel gains negative camber with wheel travel. So the wheels can tuck in and clear the fender. I'm not sure on actual numbers for how much camber gain for wheel travel, but it does tuck in.

for the front, i have 18x9. i was looking for a tire that slightly square or a barely pulled on the sidewalls. i definitly dont want bulge on the front. the 255/35 Bridgestone S-03's i have up front appear to be pulled/stretched so thats why i was thinking about going a hair wider. plus, the sidewall is so short compared to the rear, going the additional width could help fill the fender a little better. with the tire on there now, there is quite a substantial fender gap and it makes it look like i have to bring the car down 2 whole inches.

ideally, id like to get the top of my fender opening to sit ON the top of the tires, visually... or perhaps a one-finger gap.

255 isn't square enough on a 9" wheel? Maybe we just look at things a little differently, but a 255 should fit a 9" pretty well. Maybe I'm just used to big stretches, like 235 on a 10.5 and have a different perspective.

What's the overall height of the tires you have versus stock height. If you're tires are too short, it's going to lower the car and give you more gap around the fender. Same as if they're too tall. They don't have to be dead on, but it helps to keep them around the same overall diameter as stock, otherwise you will be running into a lot more problems when trying to lower the thing to a good height to look good. You will have to bring the car lower to get rid of the gap and the chassis will already be sitting closer to the ground because of the shorter diameter, so you will have less ground clearance for the same fender gap as a taller tire.

id think that you could get 275's up front with the right sidewall height and ride height. those 265/30/19's fit pretty well and the car was lowered. the tires even looked stretched on those wheels so i think a 275/30 would still fit on the same setup. but again, im unsure of how well itd interface when turning and going over bumps. i have a feeling that theres a good chance the tire could grab the fender on hard turns like driveways if i didnt take them slow enough. i had that problem on my RX7 and sean/2jzmk3 does too w/ his advans.

the 315 in the rear, im quite convinced there will need to be some pulling or going back to stock ride height. the 305/25/19 i put on the rear of my old car, was +50 and hit the strut at full droop. i had to put 10mm spacers to push it out and the tire STILL touched the strut. only after i put the car on the ground did the tire gain space... even then it was only a few mm tops. so basically, with the tire nearly Touching the strut and a 19x11 with a 305/25, it BARELY protruded past the body line. if i was able to run that w/o rubbing inside, i would have to do some fender rolling and a slight pull or mess with the camber.

Well I don't have much choice with sidewall. The tires are 275/40/17 and 315/35/17. So they're a little taller than I would like, but hoosier doesn't give you too many options. Maybe I'll just step it up a little and run 18x10.5s all around with 285/30/18 on them. That might even be easier to fit.

So we'll see when I start messing with trying to get them to fit. I have some work to do before then so that I can even use the wheels. The faces on one pair a lot thicker than stock, so the wheel studs aren't long enough for the wheels. So I either need studs for the hubs or studs for the spacers. It's going to be interesting, a lot of test fitting.

my rear tires are 26.3" tall, the fronts are 25.9" tall.

i undertand what you mean by stretched when you say 235 on a 10" wheel... thats REALLY pulled/stretched in my book, lol. but my 255 up front on my 9" wheel recommended to me by my tire guy who sells/installs lots of tires for Mkiv's and i told him thats what this set was for. so the 255/35 is typical for a lowered mkiv, im sure. so, compared to your defniition of stretch, my tire would be "Square" for you. i should probably stick w/ the 255 since the sidewalls look tight. going wider would probably make the fronts square/mushroomed. in theory, i dont think id even want a square tire up front just for the sake of steering response.

i looked at my car again today, and it Should come down about an inch in the rear and over an inch up front to look decent. i do have quite a bit of clearance under the car itself, at least 6" from the pinch weld to the ground. if i go too low, i may have to change my side pipes.

i really like your idea of 285's all the way around. itd certainly make handling alot more neutral without having to tweak all your settings. you dont mean getting long long studs to go thru spacers and the wheels do you? that sounds kind of scarey. i saw a 1300hp mkiv shear the lugs on his welds at the track. he was running 1" spacers... craziest thing ever but i guess its too be expected. maybe itd be safe to run the stock studs, bolt on the spacers that have the second set of wheel studs and change out those studs for slightly longer ones.

speaking of spacers, since i didnt buy those 19's, i have 1" spacers that i dont think im giong to be using now... what the hell can i use these things on now? lol

got a ?

here's my setup, f 225/40 18x8 35 offset and r 255/35 18x9 38 offset. can you fit 255 on 8" wheel? i want to run 255 in the front also but not sure it would fit.

I ran 255/40 in my old setup 17x8 in the rear and it didn't look much bubbled, don't know how it would look with the 35 aspect ratio but you maybe right about some rubbing issues though.

18x9.5 +12 in front and 17x10 +25 in the rear about -1.5 camber all around.

So is he just not running a front sway bar? Or never turning the wheel enough to realize that they'll hit?

Looks like I missed my queue. No, it doesn't hit the sway bar, it rubs the lower suspension arm. It's miles from the sway bar and anything else... clears the fender lining, fender itself, strut, ect. The sways would have large patches of missing paint if they were being contacted, and I assure you they don't.

We've discussed it to the nines and decided that since it only rubs very close to lock, oh well. The only time I need to turn that sharp is in a tight parking lot.

Adjusting the locks or getting new rims is on the list for the spring. The 9.5x17 +50 MkIV rims give a nice flush look on the front, but I think a 5-8mm spacer could probably take up the difference and make them not rub. I'm going to try that once she's out of the stable from the spring.

Boris, why are you running 2 different types of wheels?

Adam


Didn't you know. This was the style in th late 90s, early 00s. BorHor is taking it back to days. :naughty: Seriously, looks like theres gonna be a new trend in Supra MKIII wheel fitment: lower offsets??
