18x9 All around offset question?

Hi

Im thinking of buying 18x9 wheels all around to my BMW E90 Pre-LCI.

Car is lowered with H&R springs -35mm front and -20mm back.
I think its the same as H&R sport.

The wheels are Barracuda Voltec t6 and size

18x9 ET38 Front with 235/40/18
18x9 ET18 Rear with 235/40/18

http://www.barracuda-wheels.com/ba/d...ack_silver.php

Will those fit without rubbing even with full load?

Iīm worried about front will it clear suspension inside?

What about rear will it rub fender?

I want the wheels to be "even" with fenders and donīt want to use spacers.

Here is picture of the barracuda voltec 18x9 wheel on E46.

The rear will need a slight roll. The front is close on the strut side you might need a 3mm spacer.

Did you ever go ahead with this size? I'm looking at running 18 x 9 on all 4 corners but only using 225/40 tires

No. I went a little more aggressive.I have ordered Apex arc-8 18x9.5 et35 front and 18x9.5 et22 rear.Im going to use 235/40/18 front and rear.

Here is a example (not my car) at 18x9.5 et35 front. Its very close to struts inside.Wont clear coilovers unless spacers are used.

http://www.e90post.com/forums/showthread.php?t=478069

This red E91 has 9.5 et20 rear

http://www.e90post.com/forums/showthread.php?t=444796

You can definitely use 18x9 all 4 corners and 225/40/18.Offsets is key factor.

For 9 wide i would say around
et35-30 front
et20-15 rear

Allthought it depends how far you want the wheels to stick out.
I know that front 9 wide et 35 will clear stock struts inside. Canīt be sure about coilovers.

Those offsets above will set the wheels about the same point as those pictures.
You can use the forum own wheel offset calculator to compare.
