Perfect offset for BMW E91 LCI ?

Hi !

Whats the PERFECT offset / et for BMW E91 LCI 2010?

I'm looking at
18x8 front and 18x8,5 rear

and also
19x8,5 front and 19x9,5 rear


I've heard that the LCI's cant handle low offsets like the pre-lci's?

It depends what your definition of "perfect offset" is...the LCI's rear track is 8 mm wider than pre-LCI...it doesn't translate into a huge difference in recommended offsets..

A conservative set up would be 8.5 ET35 up front and 9.5 ET45 in the rear. Or you could go more aggressive with a 9.5 ET33 in the rear. Really a matter of personal preference

i don't have the LCI, but the body should be the same.

i have :
M5 replica Wheels, "made in Italy" model (Forest Srl - PICT.244 / Replica 244)
Front : 8x19'' / offset (ET) = 37
Rear : 9.5x19'' / offset (ET) = 28

rear is very nice, i had my car lowred of 5cm.
the front should be smaller that 37 to be much more nice.

so, that's my experience, don't know if the LCI make a big difference

Perfect fitment for me is = Aggresive offset - but absolutley NO RUBBING at all.

When you wrote 8mm wider - do you mean 4mm each side or 8mm each side?

It's an 8mm difference in the rear fitment because of wider track width on the LCI. The fitment on the wheels are the same (even though the 18" style 287 is ET39 in the rear).
