I am thinking about purchasing Volk SF Challenges. The sizes are

19x8.5 and rear are 19x9.5. Front are 21 offset. and rear are 23 offset.

I am not too familiar with offsets and such. Would this work for a stock 2006 non brembo 350z? Also, how wide is the lip of the wheels. I've found a nice deal and want to know if these will work. Thanks so much.

 

this is a pretty conservative setup, and will look slightly tucked compared to the normal 9.5/10.5 setup. The lipts will be smaller also, I think wired24/7 has a 8.5/9.5 challenge setup, search for his pics

 

That seems pretty conservative.

I run close to the same offsets on a 9.5 and 10.5 wheel. You probably won't get much rear-lip on the above setup.

 

19x8.5 +21 = 63mm lip
19x9.5 +23 = 81mm lip

that setup will clear bbk as well.. If you want a nice lip I would get 9.5/10.5

 

I have SF Challenges in the 19x8.5F 19x9.5R with the +21 +23 offsets... They're perfect if you're not going to lower your Z. When you get the larger 10.5... it looks silly if you dont lower it. It's hard to explain but you see more of the top tread of the tire. Search my latest posts for pictures of my car, you can't go wrong with that set up IMO.

Does TPMS work on SF Challenge?
