Hi just wondering if anyone can tell me the wheel offset for a classic shape impreza? Is it et42-et48?
Cheers
Craig

 

What model you got?

 

48-53.

Tony

 

It's a uk MY00

 

ET53, same as mine. They are 16" 6 spoke right?

 

am i right in thinking that the lower the offset the more the wheel sticks out??

 

Yeah

 

i thought it was the other way round, the higher the no. the more it is away from the hub,so ET48 would clear 4 pots whereas ET38 wouldnt

hmmm

 

Ive got 4 pots, I'm getting some new 17's but wasn't sure what he offset should be

 

No, the higher the number the greater the inset, whichd be a better name for it.

For every inch the rim width does up, you need to increase the new wheels offset by 12.5mm, in order to keep the centre of the rim where the manufacturer intended.

still confuzzled, but in short does that mean for argument sake that say offset et100 would be like a mega deep dish rim and et10 would be a flat spokey non dish wheel like the oz super t's?

 

If you have a classic with standard wheels with an et of 48 and you fitted wide arches to it, you would need to lower the et down to about et 15 to make the wheels stick out and fill the arches, hope this is easy enough to understand.

 

o.k,so as my wheels are ET48 and the spokes are a wafer bit away from my 4 pots,you can get 3 sheets of paper between the pots and wheel spoke,if i were to get say, ET 40 That would give more clearance ?

but what would this do the look/handling/camber etc, surely you can just fit any ET wheel to a car ???

cheers

 

cheers just what i was trying to say but not. i was looking at arch extensions so thought et25 would fill out the arches a bit more than getting a wider wheel us such

 

On a Turbo 2000 the wheels are ET53 and 7" wide. If you wanted them to stick out more you could either get new wheels with an offset that is lower such as ET40 or get spacers which in effect lower the offset without getting new wheels.

You can't just put any offset on a car, it all depends on the width of the wheel and still there are other possible problems such as tyre size/design and suspension.
If you got a 8" wheel on a Turbo 2000 and kept the offset of ET53, the chances are it would rub due to the space behind the wheel available. There isn't a lot on a Turbo 2000.

You need to compensate for change. If you got a 8" wide wheel you would need to say, okay that's .5" on each side of the original wheel, keeping in mind the original ET of 53 and a 7" width.
So .5 of an " in mm is 12.7mm. So for this 8" wheel to fit as your standard 7" did you would need to lower the ET 12.7mm to around 40.

My classic Turbo 2000 isn't lowered and i fitted 18" X 7.5" ET48 with no problems. It's about 2mm of the original positioning but fits.

^ That explains it. Typically, Classics will use 48-53, though you might get away with 45 on 7" rims without going WIDE on the tyres.

Prodrive PFF7s made for the WR1 are ET51 and 8" wide. They either just fit under Classic arches or require some manipulation.... I.e. Bending of stuff to fit.

I'd expect there to be issues with 8" wheels or if fitting taller/wider tyres than 215/40x17 or 225/35x18. Even the 225s can rub and that's on Prodrive specified rims.

No, the opposite is true. On, for example, a 10" rim, ET100 (100mm 'offset') would have the wheel face flush with the rim edge; whereas ET10 would have a "mega deep dish".

Thats why I suggested regarding it as 'inset' as opposed to offset, because when viewed that way the figures match what you get and it makes more sense.

 

a ha it all becomes clear. its like needing 40 sparkies to fit a lightbulb lol

 

Just because it's a low ET such as 10, doesn't mean it's deep dish. The point where the wheel bolts on will be "Deeper" in the wheel, but deep dish is a design.

 

...and also a product of rim width, but we know what he means...
