Looking for some advice - prepping Z for first track day
Hello everyone,
I am in the midst of preparing my 2012 370Z Sport Pkg for my first open track day with it next month (planning to run at Buttonwillow Raceway configuration #13). I have been running AutoX every month this season, but as we all know circuit racing and parking lot runs are two totally different animals. The car is pretty much bone stock with the exception of short ram intakes and Bridgestone S-04 tires (245/285). My question for all you guys that have gone road racing in your Zs is what are the must have parts that I will need to make sure I don't kill myself or my car on the track day? I daily drive this thing as well, so it needs to stay streetable'ish. I know that '12+ cars come with an OEM oil cooler of sorts - is that going to be enough or am I going to want to upgrade that to something aftermarket? The general consensus from what I've read on the forum is that cooling is the main issue these cars have when running track days (even yesterday on an 80 degree day of autoX my temps were creeping past 220F). I've also heard that anything less than a 34 row oil cooler is a waste of time/money... Anybody care to chime in on this? Should I upgrade to a colder thermostat as well? What about something like the Motul MoCool radiator fluid additive (claims to lower temps by 15-30 degrees) - is this something worth looking into or using? In terms of braking I am planning on upgrading to drilled/slotted rotors, SS brake lines and RBF600 brake fluid already (Z1 upgrade package). Who can recommend the ideal set of brake pads that can deal with track duty as well as daily driving (if there is such a thing)? I've run Hawk HPS pads on other cars in the past and liked those. I will be running the aforementioned Bridgestone S-04s on track unless I get my damn tax return money back in time to buy a set of dedicated track wheels and stickier tires. Is there anything else that is an absolute must-have before hitting the track in this car? Thanks for any input! |

I also have a 2012 Sport, and I had to agree to my wife's terms that I could only put something on the car if she didn't notice ;-). Other than the exhaust, I have been trying very hard to be clandestine with my modifications. Since I am doing the One Lap of America next month, I definitely had to make some. There is a great thread on track day prep/practices that you should read...but here are mine in what *I* feel are the order of necessity...
1. Oil Cooler - Plain and simple you have to have it if you track your Z. The 2012 OEM "cooler" is more of an oil warmer...garbage for track days. 2. Brake Fluid/Clutch fluid - DOT 4. Motul RBF600. Just do it. 3. Brake Pads - The OEM pads will...work? But they will fade fast. Carbotech XP8's all around, and they can be changed at about 5 minutes a wheel. 4. Alignment - You autocross so yours should be good. Recommend 0 toe front, and 1/16 in per side rear. About -1.5 to -1.7 camber in the rear also. Other things you can do such as front swaybar, brake cooling, and Road Race pump...but you don't absolutely NEED those. Your car will like you for the first two, and you will fuel starve under..say...3/4 a tank without the road race pump. Tracy Ramsey |

You really don't need to do anything you first track event except a fresh brake fluid change. You need to top off your gas tank at least every two sessions. It wont be until your second or third event that you get fast enough to start running into cooling issues and you can make changes as needed. You will then need to start topping off your gas after every session.
IMO skip the rotors and SS lines. Good pads, like the Carbotech XP10f/XP8r and Motul RBF600 are all you need. Just swap in the pads when you go to the track and go back to stock when finished. You will want to put in good diff fluid and tranny fluid as well. You don't need a huge oil cooler until you get more advanced. A 19-row would work well enough for a novice-intermediate level driver. |

Ah yes, the fuel starvation issue... I thought that really only got to be a problem at under 1/4 tank? So you're saying I should pretty much make sure to keep it topped off the whole day to avoid that problem? For AutoX I make sure it stays somewhere between 1/2 to 2/3 tank and haven't had any issues... But again, cone killing and track driving are totally different so I defer to you guys who have actually been on track with these cars.

Fuel starvation really depends on the track configuration. Do you have any long right hand corners? If so you probably don't want any less that 3 dots from full.

34 row oil cooler is not even enough, but you will be fine for a few days wo it. Just watch your temps. If you are going to keep tracking regularly, you will need a 34 row cooler and a real racing radiator. I have the CSF triple pass and a 34 row Z1, and cooling is no longer a problem. Lots of guys have said that a 34 row alone doesn't cut it. I would steer you away from hawk pads and pointed you either at Project mu club racers, Endless MX-72's, or really anything besides hawk. I have never used them but the general consensus I hear about them is they chew through rotors pretty bad. Use a good synthetic oil. Change it frequently. The MoCool thing works, but be careful with the water you use, use only RO/DI water. We just had a discussion in some other thread on this topic. Basically, people use tap water and MoCool/water wetter and then complain when their radiator corrodes. You have to use deionized purified water(just like itsays on the bottle) -anything else and you risk doing somoe serious damage to your engine insides.

If you have a stick. Wrap your clutch line down by the tranny with insulation. This will help with some CSC problems that pop up. Yellowstuff pads, you can DD with them too. When you get more speed. Then you can go to a different pad then.

You don't NEED anything and yaaaa OEM oil stabilizer with suffice if u take breaks between. 34 is overkill unless ur Turboed/SC Go with 25 row ($50 more than 19) from Stillen. Setrab upgrade is overkill too. Make sure u do the oem oil stabilizer delete other wise it'll cancel out ur new cooler. Everything else will work fine but if ur gonna do track alllllll the time then ya upgrade brakes ( posi quiet, min dust and noise n great for DD) SS premium Z1 lines, and mogul 600 oil. I also run redline motor oil and a purolator filter. Some Stillen sways might be an easy upgrade but that's up to u. Don't worry bout tires unless u NEED them. Run what u brought.

That being said, you probably won't be putting in times fast enough to warrant a full 34 row your first few track days. I run the OEM loop, the CSF triple pass, and full 34 row. It has yet to see 260 since, but I have not been in 100+ degree heat yet with it so we will see. Lot of guys out here run two 34 row coolers with fans just to maintain temps. AE Performance at one point mfgr an 88 row oil cooler, and it is completely not out of the question for SoCal/Vegas track conditions. My honest opinion is that the CSF triple pass is really the answer and the only reason I am able to get away with a single 34 row. The CSF triple pass is a beast. ButtonWillow 13 is unfortunately one of the worst fuel starve tracks you will encounter. There are at least two spot that will starve you out-cotton corners and the buttonhook. Bring your own gas if you can, but they have pumps at the track as well.
