Hi all,

I'm still concerned about rear clearance since my existing setup in the rear rubs a tad under full compression..

295/30/19 Michelin 4S on OEM 19x9.5" rims with around 1.8 Neg camber.

I don't want to order the Falken RT660's 305/30/19 unless I'm sure I can make it fit on either 10.5's or 11"s with a 45 offset.

My math is as follows:

OEM> 19x10" with ET 40 with the 295/30 Michelin 4S's.

Going to the Et 45 11" rims I'm gaining 8MM outside and 18MM less on the inside just for the rims.

Going from a 11.9" SW 295 to a 12.5" SW 305.

Its great that a few of you have fitted 305's with success..

Just worried about the math here...
