( i think the offset is +20 ) but am very uncertain. thank you!!! ps will i need to roll fenders because im dropping as low as i can ( have coilovers )

No rolling needed.

thanks much Jay...

what's the camber should i expect on this set up?

No way to predict that.

[Mystikal]

So I'm trying to roll my rear fenders but there is some kind of lining that wont let it fold all the way back. Anybody have any idea what this is and can it be removed? I saw on a thread on another forum about some e46 guys having the same problem and that it was some rubber lining.

Hardcore undercoating? That didn't come from the factory.

How bout 16x8/9 et 20 on 215f 225r/40/16...?

Perfect. I'd go 205/45 on the front though.

Racing hart type c.
17x8

Will I neeed to run spacers?

Yes, 15mm all around.

Brock b1's 16x9 all around et-15 will i need spacers and if so would 1/4 be enough also debating on what tires to run 225/45 or 215/45 and how much fender rolling i will need.
Thanks!

225/45 won't work very well, and even 215/45 requires a very good roll + linear spring rates (coilovers).

ok, stock fenders. 10" wide rims... meaty tires. possible?

It's barely possible with 8" wide.

i just bought some 16x7 et 20 m68 reps for my e30, wanted to know if there will be any fitment issues on offset and if i can get the same offset as i have on my 14" bbs et 30

hey there. front wheels are 17x7, rears are 17x8.5 both are et25. car is lowered about 2" all around, early arches. i was thinking 205/40 and 215/40, but i dont want the stretched tire look.. what would be a size bigger? any fender work? thanks!

4x100 M68 reps? Interesting. They'll fit fine, even with 225/45 tires.

215/40 F 235/40 R. Rolled rear fenders, nothing crazy.

[MC Hammered]

Yes, +23 will clear with a flat fender roll.

Bump it up to +28ish for a 245/40.

Thanks for that info! :D

Just wanted to clarify since you said "+28ish"... so a 17x8.5 ET30 wheel with a 245/40/17 tire will fit in the rear without issues or fender work?

*crosses fingers*

17x8.5 et15 with 215/40 and 17x8.5 et30 with 245/40 would be a nice combo.

[dmoney(AB)]

how bad of spacers would I need for these?
also what would be the bet tire size for them

17"x7.5" F +33
17"x9" R +40

You *might* need to grind some material off the little protruding seam on the trailing arm (inside clearance). No biggie.

You want flush, big rubber, or something in between?
