FI guys who track-What are your wheel/tyres setups?
I've been using my stock wheels and R-spec tyres as my track wheels but I'm now looking for a wider set-up in order to get a little more traction.
I'm thinking:
18x8.5 with 255 tyres front
18x9.5 with 265 tyres rear
I'm interested in knowing what wheel/tyre set up people are finding good for the track.

I run a set of 5Zigen FN01R-C. Availability was limited a couple of weeks back, but they migh be available again.
17x9 +35 Front with 255/40R17 Toyo RA1
17x10 +35 Rear with 275/40R17 Toyo RA1
I like the setup. Some prefer to go with 255 all around to reduce the understeer. I run half a tank of fuel to keep the rear "livelier" (275 should fit with this setup too, do NOT get the 17x10 for the front, they will not fit).
I have a Track Z (w Brembos) and Koni dampers (to match the R-comp tires)
There are other options. Do a search in the AutoX/Road forum and you'll get tons of options.

I am running 285/30/18s hoosier A6 tires all the way around but I am an autoxer... When I go to the track I just use my streets which are 245 in the front and 275 in the rear...

I do have a Z that is FI and do track my car at Road coarses. My car dynos at 440 rwhp and 400 rwtq.
I use Pilot Sport Cups with 265 front and 295 rear. I am really happy with the performance and the life of these tires!! With an FI car, you need a lot of grip on the rear to be able to lay all that power down in the middle of the turn, yet you don't want to go to big in front or else you add more unsprung weight and rolling resistance.

18"x 9.5" +30 all around with Michelin Pilot Sport Cup or Hoosier R6 285/30/18 Front 315/30/18 Rear. The 315 is not ideal for the 9.5" rim, but it does work. The best setup would be a 18"x 10 or 10.5" wheel in the back, but I can't find a single one with a +30 offset.
Pretty sure the WedSport SA-70 18x10 has a +30 offset and it's only 20 lbs and sells for about $380 per wheel. These are the wheels that I want for the track but I want to run the 18x9 up front and they have been on backorder for quite some time, I'm hoping they are in before the end of the year. Oh, these are distributed through TireRack if you want to check them out.

EDIT: Did some research, the closest they come in is 18 x 10" +32 and 18 x 9" +35. That front wheel kills it for me. I would need to run a 2mm spacer in the back and a 5mm spacer in the front. I will probably just end up widening the rear Nismos an inch.

350ZNV and I have learned that the same set ups cannot be run on the Z and the G, the wheel wells etc and just different enough, especially in the rear that the limits (without getting into pulling/rolling the fender wells on the outside or tubbing the inside) are different.
On the G we are running 9.5 Enkei NTO3+M wheels with 27 mm offset in the front and 10.5 with 30mm offset in the rear. Then, with 3mm spacers, we put Nitto NT-01 tires on, sized 275/35/18 in the front, and 315/30/18 in the rear. (The actual treadwidth measure on that tire in the rear is 323mm).
We discovered that we could fit the rear on the G, with a very slight trim of the inside metal lip, and the entire set up tucked nicely even for hard running and cornering. It gives HUGE grip in the back. It just will not work on the Z....close, but no joy with that big a Nitto. However some other tires in 315 do fit.
So the advice is to be precise with what your set up is, and what somebody else's is, to get as much advice from experienced tracksters as you can, and make sure it is ABSOLUTELY precise. You do not want to have a blowout due to a potentially hard to detect inside rub problem because you just happened to overlook what your rear camber was as contrasted with somebody else that had what you thought was the answer! Seeking performance enhancement is lots of fun and not hard to do when you are excited at the prospect, and in a hurry. Understand the difference between performance enhancement, and pushing the envelope to limits commonly encountered. If you don't immediately understand where that is, in any area of endeavor with respect to your car or your driving, SLOW DOWN what you are doing and think and find out before you commit to something. The consequences at the edge can be as extreme as the sought after returns.
Safety first. "More" is not only not always "best", but in fact ultimately always bad. "Balance" among capabilities is what you must seek. If you do not, you might actually degrade overall performance of the platform. And when you push the performance of one aspect, you will almost always have collateral consequences. For example, if you go this type of sizing of rubber, you have unsprung weight issues that you must consider, mandating light and strong wheels with different offsets and , differing camber adjustments, possibly greater brake needs, and you must get a powerful cooler for the power steering. Think through all the dimensions of your change and what that will do, not only for this step of improvement, but others you may make later.
Good luck.

Hi Mike!
Out of commission for a bit. The last 60 days.
Summer cuts back on my track days. The car can take it, but I cannot!
I hope to get back at it this fall in earnest.
Second week in September the car is on the cover of Nissan Sport Magazine, so be sure to grab your copy. It is a new iteration of the old Sport Z, but much bigger, probinding, lots more articles, totally slick.
Next week meeting with a TV reporter on the car, maybe get some coverage there which could be fun.
Then in October the car is possibly slated to be in a TV advertisement for a new video game, to be run at Laguna Seca. So even though I have not been able to see you at the track garage, I have been doing something productive with my life!
Loading up the G now to take it to Irwindale to deliver it to M.A., who is there for a drifting event, and he is going to take it to SD for a little TLC. Got a couple of small fixes to address, and I just do not have the time or facility (yet) to deal with them.
But the new wife has me hopping all over the place. Cleaning up stuff, reorganizing every drawer in the joint. Taking stuff to storage, to charity, moving her stuff to the house. It is all long overdue and all good, but no track time.
And working with architect on remodel that in addition to combining some bedrooms into suites and adding bathrooms, is going to add about 2,000 feet to the old homestead. The good part is that it will also include a new four car garage with a lift and parts storage and work area! And a pad for the trailer and tow vehicle. Yippee.
Keep in touch with your emerging track schedule for the fall and I will try to hook up with you at one of the circuits.
Cheers.

Congrats on the marriage, Ed! My wife and I just had our first child on Aug. 14th, so I have been kinda busy myself.
Hope to see you and Mike B. at a track soon.
I'm planning to go to Buttonwillow with Speedventures at the end of September to try out some new aero and carbon fiber parts. Maybe I will see you guys there.
Quick question for both of you guys: I would also like to run a 315/30-18 tire in the rear. Specifically, the Falken RT-615 (since I need to run street tires in the Redline Time Attack). I have a set of SSR GT-2 wheels, 18x9" for the front (275/35) and 18x10.5" 43mm offset for the rear. Do you guys think these will fit on the rears? I have tried but I can't find anyone who has attempted this combination yet. I know that the 295's will fit on the rear using these rims (someone else locally has these), and if the 315's won't fit, that is what I will have to go with.
Thanks.

Congratulations on the baby! That is fantastic. Little short on sleep? Maybe?
I have not tried the Falken in 315 so do not know if it will work. When you get it that close to the max it really is a try and see situation. Sorry I do not have the experience with that specific tire.
I cannot make the Buttonwillow event due to a business trip to Chicago, alas. Life on the track will not return until October-November for me.
May change out the coilover set up to something more custom with our friends at VRT.

Yeah, she is getting my wife and I up 3 or 4 times a night. I'll be glad when she can sleep through the night. But it's all good.
I expect that I may need to either use a spacer or roll the fenders or both with the 315. It sounds like there is room in there if Mike B. is running that size, but as we all know, the tread width and cross sections of tires from different manufacturers can vary quite a bit. At least I have skinny shocks instead of coilovers, so maybe they will fit on the inside and I just need to roll the fenders.
I agree it is a "try and see" situation. Luckily, Brian ("arizzee" from this forum) has agreed to buy them if there is a fitment issue, since he plans to roll his fenders or do what he has to do to make them fit. I also have a very friendly tire guy who will order the 295's if the 315's don't fit. I'll be sure and report back on this forum whether it works or not.
Hope to see you later this fall. Take care and enjoy married life!

Wow Ed, you have been doing a lot! Congrats! And congrats again on your new baby Steve!
As far as the 315s on a +43 offset go, I am not sure about that. My 315s on the +30 rubbed on the JICs just a hair. Do you have longer studs? If you do, try some 3-5mm spacers if its a tight fit on the inside.

I don't have longer studs at the moment. I will certainly need them if I put any spacers on. I'll order some Nismo 60mm studs and some 5mm spacers and hopefully that will solve the problem. (It figures - I sold some nice H&R spacers with longer studs a while back since I didn't think I would need them.) I really don't want to go bigger than 5mm on the spacers. If not, I'll just be stuck with the 295's - that's still a decent size footprint, plus the tires are less expensive.
