21 wheel question

Right now I have 21x9 35mm offset in front and 21x10.5 35mm niche Essen wheels. I now have oem m5 fenders in front which are much wider and my front wheel sticks in. My question is can I run the 21x10.5 35mm offset in the front with the oem m5 fenders without any issues or will it be too wide? I'm looking for a flush look

i think it depends on the wheels. i know ismet did it because he wanted deep concavity in the fronts but those AG's he had to order the same for the rear for the fronts. i'm not the wheel expert...remmib is! maybe he can chime in. what wheels do you have? i know the lower the offset the more it pokes so i'm guessing with 35 it will poke more than the 38
here's mine 21x9.5 30mm

Correct.

Lower offset means more aggressive fitment. 3mm more in this case.

Yes, you'll need spacers.
In the ismet thread, he mentions both having ET22 and ET29. For your ET35 wheels, that means 13MM spacers or 6mm spacers. (35-22=13 and 35-29=6).

Thanks for the response guys! But I'm confused lol sorry. So I go with the 20x10.5 et35 and add a 13mm spacer or 6mm? And do I have to shave off any offset from the wheel?

Shaving off the wheel will give you the opposite effect as putting spacers on, so no.
I just mentioned 13mm and 6mm because that's the difference to the offset mentioned in ismet's thread. And normally you only get spacers in 5, 10, 12, 15, 18, 20mm sizes.

It doesn't have to be exactly like his as long as it's flush so would a 5mm spacer do the job?

I'm not sure if 5mm will clear the inside of the suspension.
