My girlfriend is going to order some SF Challenges for her '06 350Z and she wants the deepest lips without rubbing. She has regular OEM non-Brembos and is lowered on Tanabe GF210 springs.

My guess is that the following sizes will work and be the best for our goals, but I want to make sure before she orders.

Front = 19" x 9.5" +15 with 245/35/19 tire
Rear = 19" x 10.5" +23 with 275/35/19 tire

I am guessing that +11s would rub both front and rear correct? I tried searching, but it is taking too long and I have to run.

P.S. - I have a fender roller, so that is an option as well if needed.

 

9.5+15 would probably rub, but 10.5+23 won't rub

If you went 9.5+11 / 10.5+11 for sure you would need to roll fender

Getting the "deepest lips" without rubbing is kinda contradictory, but I know what you mean. Just get the +11's all around and roll the fenders if lip size is her main concern. If driveability without rolling is her goal, then get the +15/+23.

I personally believe in the "make it fit" attitude.

 

^^^Thanks! Can you even roll the front fenders? Would the fender liner still work?

 

I have 10.5 +23 in the rear. It rubbed with 285/35/19 but I doubt it would rub with 275/35/19

The fronts are ALREADY rolled. my fronts are 9.5 +28 and are just ever so slightly tucked in.

+15 is kind of agressive, I'm not sure if it will rub or not. Seems okay but I can't be sure.

 

Thanks!!! Do you have any pics of yours that are larger than your sig?

 

Found this thread that says +15s on the front wont rub!!!

+1 plenty of room up front

 

Looks like +15 Front +23 Rear is the way to go!!! I will post pictures when she gets them.

 

When lowered, my car rubbed over bumps on the freeway with 10.5" +22 275/35/19's. Rolling the fender will fix it though.

 

Rears will not rub with a little negative camber.

Fronts will rub without modding the fenders for sure, unless you run -2.5 camber or more..

Good Luck!
