Default Wheel size ?

First of all I want to introduce myself: I'm the fresh owner of a Legacy sedan 2000 in that blue-isch / purple-isch color. I fill my days with selling high-end car audio and studiing half time. For the record, i live in Belgium and English is my thirt language, so please don't mind the typo's.

The fist thing i want to do is get rid of those ridiculous steel wheels and get me some nice looking replacements. Since i really LOVE large wheels i'm tending verry much towards 18's.

BUT ...

What about the width of the rimm and the ET value? I know the official ET value is 53 but i still have to find the first after market wheel with that offset. So, how far can i deviate of the official value without getting into troubles? And ofcourse, this goes hand in hand with the width of the rim. So wich ET/width combo will alow me to do the same as with the stock wheels? I'll be also lowering the car for about 1.5 inches.

Some calculating with the online tire calculator already told me that the circumferance can be kept the same as stock with 205/40/18 or 215/40/18. Stock i'm having 195/60/15. So thats not really an issue.

Since finding wheels in 7,5 x 18 inches with an ET of 53 looks imposible i want to find out how much i can deviate without getting into troubles. Hope you guys can help me out ...

PS: I DID use the search but couldn't find a completely satisfying answer. Only I got the id that deviation IS posible without to much trouble.

You would be FAR better off deleting this post and putting the same text into a post in the Suspension, Brakes, Rims & Tires

You can mostly follow the same setup as an impreza. See what 18 inch wheel and tire combo WRX owners are using

Try Rota Sub-zero 18x7's with +48 offset and 215/40R18 tires

Personally I think 18 inch wheels are a joke, the performance hit for what a small (yes small) group of people think looks good is not worth the trouble. The increase in rotational mass that this combo will produce is substantial.

18x7's with +48 offset and 215/40R18 tires
I'd agree with this if you're wanting 18's. Your ET will have to be lower at that size to reduce rubbing possibilities. The suspension you use also will make a difference whether you'll rub as manufactures springs/struts all lower the car differently. Also not all tires that are 205 are exactly the same, so you might have to try different rubber to find one that works and won't rub. If your going just for looks, go for the 18's; however, I'm with ciper in that if you want performance stay away from 18's. 17's are a decent compromise

I'm pretty sure both the 17" and the 18" Rotas are 7.5" wide, with an offset of +48mm.
