Hi, I'm fairly new to the supra forum. I bought a 1994 N/A about 6 months ago. I've always wanted a supra and now that I've finally got one, I plan on making it look as nice as possible. I found a set of wheels on the Internet that will look sweet on the car... The fronts are 20x9 +30 and the rears are 20x11 +38... my question is, will these wheels fit without any rubbing issues... Also my car is at stock height...

Oh yeah, and what size tires should I run on them.

They may not fit perfectly. I believe the oem offsets are +50.

On an n/a, traction isn't an issue. However, with that large of a diameter (20"), you'll want a very narrow sidewall on the rear to reduce the inaccuracy of your speedometer. The narrow sidewall will also help reduce rubbing issues.

pplllzzzzz do not put 20s on your supra

Why not? It can be done...especially on an n/a where you don't need to worry about rear wheel traction:

cuz it doest look right but there are some exceptions but not many
a supra is a sports car even if it is a n/a big wheels just take away from the car there not cadillacs



alittle more info V

Thankyou for the info... I think i'll look into a set of 19"..... 18's im a little skeptical about because i dont want to get a set of wheels and they look too small on the car...

18s wont look small im running 18s on mine they fit the car perfect
19s and 20 would be to big there where 19s on the car when i bought it an i thought they where alittle big

I guess this is a pretty subjective area. I believe this setup looks great::dunno:
http://i31.photobucket.com/albums/c4...re060small.jpg

but its a widebody
put those rims on a stock body supra and i think the rims wouldnt work to good and you would need thinner rims to fit a stock body

and also why doesnt the origanl poster of some of theres threads come back and post lolol

True, but they'd still be 20s in diameter... and besides, you can fit wide rims under fender flares - no need for a widebody.

:bow: this is the look I'm trying to get for my car... What size are these wheels and tires and what's the offset? I have to put my car in the shop to get painted soon, so if I have to roll my fenders to get the wheels to fit, I would rather do I before the paint job...I will post some pics of my car soon, I've just been responding through my phone and can't figure out how to post pics on this site as yet... I'll try again this weekend...

Pretty sure that's a widebody Mkiv. You'd have to do a lot more than just roll your fenders to get those wheels to fit (due to their width, not their diameter).

I'm riding 20s

Thanks for posting the pic - your setup looks great.

If you don't mind me asking, what is your rwhp (approx.), and how is your traction from a dead stop?

I only have a base, 5 speed manuel.

I like the look of 20's as well, but I would be afraid of the ride quality with that slim of a tire. I just bought 19's for my Supra the other day. My question to you guys is what tire size should I go with front and back? My fronts rims are 8.5 inch wide, & my rears are going to be 9.5 inch wide. What size tires do you guys recommend? I was either thinking 275/30/19 or 285/30/19 in the rear, & 235/35/19 in the front? I am also selling what I have seen in the picture below, PM me if your interested or if you want more information about them! I will also put an ad in the classified section for the wheels I am selling.


Oh & I don't want to roll the fenders, if that makes a difference. I am also installing TIEN coilovers as well,
Thanks guys! :rofl:

sorry about the blurriness of the first picture

love the look with the red accent! Awesome car man

What is your rwhp? This should be your starting point to determine your rear rim width. Since you say your rears are going to be factory-spec 9.5 inch, I hope you're planning to limit your hp to factory specs too (320hp).

I see. Traction isn't an issue then. Hmmmmmm.....

The current wheels I have on my Supra are 18's & they are 8.5 in the front, & 10 inch in the rear & I run 275 in the rear. HP came in at 350 last time it was on the dyno
Thought Im looking into having the rears widened cause I like them so much but they didnt come in a larger size, like a 10 or a 10.5 like i wanted.

If that's 350rwhp, then that's at least 28.7% more hp than stock (350rwhp /.85 = 411.76hp vs 320hp oem spec - please feel free to double-check my math). This means that your rear rims should have been about that much wider than stock...which is already about a 12" wide rim (11.5" would be fine, since that's the max that fits under the oem fenders). That'd be about 315mm-width rubber.

You can't run oem width rear rims and oem width rear rubber unless you're running oem rwhp. I know a guy that tried to run his stock rims at BPU on a MINT/PRISTINE <20K miles '98 Mkiv Supra, and within hours he ended up smashing it sideways into a big rock in a ditch. That's just ONE example of many. Every single component on the ENTIRE MKIV SUPRA TURBO has been spec'd and designed by Toyota to work together by highly qualified automotive engineers with decades of training and experience. You just can't go bumping up the hp and expect nothing else NEEDS to change. When you go BPU or beyond, one of the things that NEEDS to change is the rear rim+tire width. In turn, when that changes, the front rim width and front tire width must change together. It's like a symphony - you can't go replacing a violin with an amplified electric guitar and expect Beethoven's 5th to still sound right.

If the rims you think you "want" don't come in the right size, then don't buy them. It's that simple. There are LOTS of companies making LOTS of styles of rims that do come in 11.5"+ widths. Please let me know if you need help finding what you're looking for.

After you figure out how wide the rubber is that you need to run on the rear, then you can pick the front rim width and the front rubber width in proportion.

Ok, lets say I decide to go with the 11 inch rear wheel, what size should the front be? Would I then run something in the 300's for a rear tire?

Thanks

I used the tire calculator on discount tire site to help me determine the size tires I wanted. I wanted to say close to the factory spec diameter. I will also tell you the speedo change with the tire tire compared to what's spec. This will help you with picking a tire size that's close to spec. Hope this helps. Here's the link: http://www.discounttire.com/dtcs/infoTireMath.dos

http://www.discounttire.com/dtcs/infoTireMath.dos (Tire Calculator Link)

That calculator doesn't help calculate traction (i.e. width) - only diameter/circumference.

1) 11.5" width rims fit under the (trimmed) rear fenders just fine, and 315-width rubber is fairly common. Why would you go down to 11"?
2) Oem specs are 8" front and 9.5" rear. That's 84%. 84% of 11.5" is 9.68" (close enough to 9.5"). So 9.5" width fronts match 11.5" width rears.

...this was my first rim upgrade. I ran 9.5" oem rear rims in the front, and 11.5" widened oem rear rims in the back.

I dont want to have to trim my fenders, or roll them if thats the same thing,

if I can stick with an 11 and not have to roll my fenders thats what i am after,

If you don't mind me asking, why don't you want to trim the rear inner fender lips on your Supra?

I've done this mod on at least a dozen Supras. It's easy, the results look fantastic (i.e. practically invisible unless you know what you're looking for), it's just as strong (really!) and (of course) you can fit 315 rubber inside afterwards.

I also had the fenders rolled on my Supra (this is before I started doing the inner lip trimming), and the results were not nearly as good. Although 315s did fit afterwards, the process put so much stress on the fender that the fender panels got slightly bent. As you would expect, this really bugged me...so I eventually got it corrected. I'm just telling you about this so you know that 1) I really do have a lot of experience with this, and 2) rolling and trimming are VERY different procedures. Please let me know if you want any more info on trimming and I can tell you step-by-step how to do it easily and effectively with no need for experimentation or figuring things out on the fly.

hey,
 

what's the proper off set for a supra, these are what i'm looking at,
does positive offset mean they will stick out?

cody

Size
19x8.5 Front, 19x10 Rear

Bolt Pattern
5X114.3mm

Offset
20mm Front , 25mm Rear

Lip Size:
2.5" Front, 3" Rear

Color:
Chrome

Hub Bore Size:
73.1 mm

Quantity:
4 Wheels

Condition:
Brand New

I don't think they'll fit properly but I'm not sure. The proper offset for oem-width wheels (8.0" front and 9.5" rear) is +50mm.

Offset is all about the position of the hub mating surface relative to the center line of the wheel...so no, a positive offset does not necessarily mean they'll stick out.

Here's a diagram that may help:
http://recstuff.com/images/trailerfa...-backspace.gif

well they fit on the car fine, but they do stick out a little bit in the rear and a tad bit on the front. I don't know if thats bad or not, they rub a little bit on the arches but won't the coil overs allow me to correct that? Those are installed tomorrow. Here is a picture of the old & new,

Yes, most coilovers are height-adjustable. However, note that as you increase the height you (usually) also increase the preloading on the spring which may cause (for example) a bit of a harsher ride (among other things).
