So I have a set of 18x10.5 +20 wheels right now.
I have a base 06 TL and I plan on running 235/40/18 on tires.
I am getting my fenders pulled and most likely gonna run -2 camber all around. will this fit/does this sound good? or how much of an adjustment will I have to make?

 

Why would you want to run improper camber in order to make the wrong size rims "fit"?

 

what's a wrong size rim?

 

you might need to go -5 camber to get it to work even with rolled/pulled fenders

I cant answer the sounds good part

watch out though for that size tire you might be riding on edge of your rim versus tire itself.. but you wont know until you do it

 

The wrong size rim is requiring the //-\\ broken suspension. A 10.5 +20 with a 235 will require way more than a pull on the front. Modify the fenders enough to run proper camber and proper tires ||-|| and thats fine. Handicapping your car for some perceived vanity is just stupid. A 215 on 10.5 with 5 degrees of camber is rediculous

 

Just curious whats the widest rim you can fit without having the fenders rolled with 235/40 setup?

 

Would depend on the offset

 

So what do you recommend me doing? I don't want to run 215's I would just feel safest running 235's.

 

I agree that you should be running 235's. in order to do that you will need to do some serious wide body fenderwork or get rims that fit properly

 

so after looking around some more... what do you think of this

18x10.5 +20

215/40/18 fronts -2.5 camber
235or215/40/18 rears -3/3.5 camber

i'm a super noob and I just really want help lol

 

I would say that you need new rims, why did you decide to go 10.5 all around lol..
The rears wouldn't be a problem if you cambered it out, but that's not my taste, having the wheels look like they're about to snap off.
The front might or will rub like a mofugga. With this set up, youre gonna have trouble driving anywhere, just sayin'.

 

If you want mexi poke rims with an unsafe stretch and compromised suspension geometry and prolly still rubbing.
