What is the offset or et of cupras?

What is the Offset / et of cupras? and what is the ideal et/offest? I've always assumed any 4x100 stud pattern rims would fit!?

Cos your a newbie il gie you one free answer, only once can i and will i do it tho lol.

ET38 is the standard offset. The lower the number the further out it will sit in the arch and vice versa for higher the number

will 9x16 fit with a 25 OFFSET

feck me.. sticky out wheels then...

 

[SupraDupraCupra]

i'm guessing that a no lol

then you are absolutely guessing wrong.

didn't think myki's answer was very difficult...

Normal ET is 38 (mine were 37 btw ) if you go for ET 25 then the rim will sit out further which on the mk3 cupra is really not a bad thing as the wheels sit in quite a bit, especially the rear.

Note though, this is only for a non lowered car. Obviously the further the wheel falls outwards (meaning lower ET) the less you can lower the car say on coilovers. Else the wheel arch will sit on top of the wheel which is obviously not good for either the tyre or arch...

Don't think I can explain this any better/easier

You want to go for a higher number offset if you want to fit 9" wide wheels. You will struggle to turn if you do as well I would think.

yeah but wudnt a 9inch wide wheel be naturally lower offset? so how could you get a wheel thats 9 inch with higher offset? its still going to be the same width the wheel ? or am i wrong?

what??

I just explained, the higher the ET the more it goes inside the arch!!!

that means if you get a 9" wheel you get a LOWER!!!! ET value. Else you'll be hitting you're suspension and can't make turns without scrubbing all over!

With 9" wheels though you will be lucky if you can fit leaving enough room for the suspension/steering components without the wheels hanging past the arches.

still though, low ET is the only way possible with those wheels.

look at all wide wheels on the market. they always have lower et value's

You're both kind of right, but looking at the problem from different directions. As offset is measured to the middle of the width of the wheel (as is track), as the wheels get wider, you need to decrease the ET so the inside edge of the tyre clears the suspension and steering. The downside of this is that it means that the wheel will stick out of the arch that bit further - and a wheel that sticks out further than the bodywork will not generally be looked upon sympathetically by an MOT man. So you'd be getting into the realms of having the arches pulled of wheelarch extensions.
