I have a C5 Z06 lowered a bit on stock bolts (not much at all) and I am going to pick up some new tires before TX2k11 and was wondering if anyone has had any fitment issues with the Nitto NT05R Drag Radial I am running the 315/40-18. The only thing I am scared of is the tire height and hope this will not effect the active handling.

I really want to pick these up as a buddy that works at DT can hopefully hook it up for me. And they have really great reviews.

According to the tire conversion calculator the diff is only about 1 1/4in taller than a tire that fits good. So thats only 5/8ths of an inch closer to the fender/wheel well.
I don't have active handling so I'm not sure how sensitive that is.. maybe just a little larger front tire while your at it??

315/35/18 = 26.7x12.4/18

315/40/18 = 27.9x12.4/18

You shouldn't have any problems at all. I have the same size tire on my 04 C5Z. The only complaint I have is the ride quality.

Awesome thanks, this is the answer I was looking for.

Edit - I just reread your post. What size front are you going to run? This 315/40-18 is 2.6" taller than the stock 265/40-17 front tire which is a pretty sizable difference that the active handling/traction control might not like. I did a quick search and the rears need to be at least 1/2" taller than the fronts but not sure how much taller than the fronts you can go.

My front tires are 275/45/17

That's a 1.2" difference b/w front and back. I run a 1.1" difference between the two and I have no issues...I would assume you would probably be ok. I think if it does have issues you can just turn off traction control.
