Wheel Offset

[SubaLegacy]

I know this has been discussed before but I couldn't find the thread. Anyway my question is... I found wheels that have an offset of +38 and they are 15x7. I think most suby wheels are +45, right. So would it be bad to go 7 mm to the negative? Are their spacers I could get? Any thing else that I might want to look out for? Peace.

What car, what size tire?

Stock subie offset is in the +53-55mm range.

I'm running +45mm on my legacy and did have to have a shave in the rear fender to get things to fit. +38mm offset for me did not work. That doesn't mean it won't work, but just letting you know.

Since positive offset moves the wheel further into the fender, you can't get spacers, only thing you could do is mill the mounting surface down to increase offset, but probably isn't a good idea.

Decreasing offset can create more loads on the wheel bearings and such.

For 7 inch wide isnt it 50-53mm on stock or 48mm for aftermarket? I thought 53-55 was for 6.5

[SubaLegacy]

Is there any reason I could not use a new MY Legacy wheelset on my '91?
How can I find out wheel sizes and offsets of newer Legacy wheels?

You will be fine using any Subaru wheels on your car. I've got '02 WRX wheels as do many other forum members.

So this means that i can go ahead and buy a set of wheels and tyres off an My03 impreza with a 53 offset even do the off set on my 92 legacy rs has an offset of 55 ???

[Legacy777]

yes

Cheers for that Josh

Go into your tool set and look at a 2mm socket (if you have it) The difference is small, your wheels will stick out 2mm on each side more than previous (assuming the same tire size).

[steeo]

So will this 2mil extra make a difference on handling or affect the geomotry (spelling) ???

[ciper]

"difference on handling" Yes,

Enough to measure, or matter? No

Just changing tire sizes will make more of a difference.

[steeo]

Cheers for that

I was onto the lad selling the wheels and should have them tomorrow afternoon

I've always used the factory recommended tire size which is 185/70/hr14. however, when i needed new tires, i tried out a set of 195/65/14's and noticed that my car wasn't as response as it was before in terms of acceleration. Can anyone explain this? It felt a little more responsive in terms of handling but less in the power department. Any info. on this would be great!

[mTk]

That is weird, the 195 were smaller overall diam, if anything you should accelerate faster.

i've always thought that if you get bigger rims or tires, you would accelarate slower but have a higher top speed. eventhough the difference in tire size wasn't significant, i felt my car weaker. don't know why? perhaps the width puts on more resistance

[Yukonart]

More unsprung weight = slower accelleration.

[J-MoNeY]

OK, so i have this set of tires i can but that are 17x7's with a +40 offset. Will they fit.

[kastrix]

Not very well. There will be some rubbing noticable on hard turns and driveways and such. But the biggie is the damage you are doing to your wheel bearrings..

45 will work ok i think...

[mTk]

More weight alone slows down acceleration, whether or not it's unsprung.
