so i am looking into getting new wheels for my fc and i dont understand width offset to save my life .. i have looked around and still cant even understand how to read some wheels site. i think i am starting to understand it but for my fc i was looking to get some 17x7 with +40 offset and a 1.75 lip .. (the XXR962) is +40 offset bad ? would i need to do something to make it better ? and what would the lip size take effect in this equation x_x .. sorry if this is to noob for someone to answer but i really need to understand this xD thanks in advance guys =]

 

Those wheels are too narrow Get at least an 8 inch wide wheel! +30 offset should be enough, not too aggressive, not too tame.

 

+40 on a 7" wide wheel is stock offset for a TII
I have ran the stock tII wheels with 225's on them with a 32mm spacer (this lowers the offset and drives the wheel out towards the fender more) which makes it +8 offset and they fit nicely with coilovers and a good alignment for autox (~2* negative camber)
