Well, as to the suitability, you can rule out certain wheels from the above list at the very start.

The STi (All Imprezas actually) are 5 stud with a PCD of 100mm. Anything other than 100 will not fit at all.

The STi ET (offset) is 53mm, so you really need to look at the higher offsets available or you will have trouble with the tyre/wheel catching on the wing of the car due to the wider track caused by lower offset figures.

The problem then on top of that is spoke shape (between the back of the wheel and the front brake caliper body). There is no way that you can predict if the wheel will fit based solely on the specifications listed above!

Speak to the wheel supplier and ask them if those particular wheels have suitable clearance to not foul the (Enormous) Brembo front calipers?

Hi,

I am going to purchase the ADVAN RC2 wheels for my STI7 and to transfer them to STI8 after some time.

Looking to Advan site I found that they have the next sizez of wheels. I absolutely have no idea which sizes will be compatible with STI7 and 8. Pls help.

There are several available sizez of ADVAN wheels:

18×7.5JJ PCD 114,3 OFF SET 45
18×7.5JJ PCD 100 OFF SET 48
18×7.5JJ PCD 100 OFF SET 35

18×8.5JJ PCD 114,3 OFF SET 31
18×8.5JJ PCD 100 OFF SET 45
18×9.5JJ PCD 114,3 OFF SET 35

Pls help.

@nton STI7

Doesn't anybody know the sizes of 18' wheels and tires compatible with STI7/8?

@nton STI7

Here is available sizez again:

18 x 7.5JJ / PCD 114,3 / OFF SET 45
18 x 7.5JJ / PCD 100 / OFF SET 48
18 x 7.5JJ / PCD 100 / OFF SET 35

18 x 8.5JJ / PCD 114,3 / OFF SET 31
18 x 8.5JJ / PCD 100 / OFF SET 45
18 x 9.5JJ / PCD 114,3 / OFF SET 35

Àlso the question: does ADVAN produce strong, forged wheels?
Thanks!

@nton STI7

MIke, thanks for your answer.
But the situation is not still clear to me. Pls help to make it clear.
What is PCD?
What is the ET (OFF SET)? Distance in mm between what?
And which size is better for STI? 7,5 or 8,5?
P.S. Also I saw the Zerosports demo car well fitted with 18' Advan wheels and with Brembo.

Have a look Wheel Tech Info
Scroll about a third of the way down the page and the explanation is there for you.

The easiest way would be to find a supplier, (In Japan most likely) and tell him exactly what you want, he will do the rest.
