Track/Course Driving on NCCAR Track

[friss]

Took the Stinger out for some laps around NCCAR. First time on the track with g-loc R10 pads all around which were decent but definitely throw A LOT of dust.

Ended after that session due to the tires looking like this afterwards

nice!! that looks so fun!! I need to get out on a track.. autocross at least

The stinger is a lot of fun on the track, highly recommend!

How were the pads? I got G-Loc 12s, based on recommendation from KNS brakes. Were your tires already chewed up somewhat before the track day?

how many miles did you have on those tires before you went to the track?

They were pretty good didn't have any fade. They do like to get a bit of heat into them first so need to know to work up the stopping power. Still better than stock cold though.

I had 5 track days already on them before doing this day (Charlotte Roval, VIR, NCCAR) so > 30 sessions out on the track.

I never got a track focused alignment on the car beforehand and for this day I went out before airing the tires down which definitely didn't help. NCCAR also eats tires more than other tracks due to the pavement.

Thanks for the info. I've never had track pads before (except for when I did an Exotics Racing with a pre-prepped car). How bad will G-Loc 12s be cold, driving on the street? I need to bed in the pads, and also decide whether I can drive to the track or if I need to swap from G-Loc street pads to the R12s at the track.

I've heard all kinds of warnings about "you can't stop at all with cold track pads", yet you said they're better than stock when cold? I just need an idea if I will panic the first time I step on them, or just "press a bit harder / longer than with street pads" the first time?

This is kind of my last "unknown" to cross before I go to an HPDE - I have SS lines, Prospeed RS683 fluid (put in last year, but barely driven - hoping it'll be ok for a few beginner laps), Mando ECS10 suspension adjuster, sways.

What suspension mods do you have? I'm thinking of just setting the Mando to something like "75% hard" to start with, and see where that gets me. I've driven that on the street, and it's stiff, but not insane. I think my mechanic got crossed up and did my sways backwards (stiff on front, soft on back) - I think most people are doing soft on front, stiff on back? Will need to maybe adjust those.

Thanks for any info. It's hard to get much info for what works on the Stinger on the track, since there are only a few doing that yet.. Seems like everyone's doing dragstrip.

Should be fine to drive to the track I just suggest you give the brakes some test runs so you know how they will act cold by just driving around your neighborhood As long as you aren't trying to stop from 100 to 10mph first thing you'll be fine. You
may need to stop earlier or apply the brakes harder but they'll still stop you putting around town.

Your fluid should be good but recommend keeping up with changing it more often if you will be tracking it more. These cars are heavy and will build up heat for the fluid.

Here's my list of current mods
- Eibach sway bars front and rear (soft setting)
- K&N Intakes
- VT Intake Snorkels
- BMS Intercooler
- MBRP Catback exhaust
- JB4 Tune (map 3)
- Michelin Pilot Sport 4S
- G-loc R10 Brake pads front and back
- Motul 600 brake fluid

I was going to try firm settings on the sways but decided to just test out the new pads this go around.

For your HPDE just remember to have fun and work your way up. The Stinger is a rocket on the straights but you may be slower than some cars in the turns and be sure to let those cars by.

Thanks for the brake pad experience. That's good to hear.

I'm a total beginner for track stuff except the Exotics Racing thing I did where I drove a 911 Turbo, 458 and Gallardo Superleggera, so I plan to take it easy - definitely don't want to go off-track my first time!

Have done a couple of auto-x, but it's too much waiting for 5 minutes of actual driving for me. I've also done a bit of winter rallying, but that was totally different. I plan to run the jb4 at map 0 for the first session until I feel more comfortable. And get an upgraded intercooler at some point.

I have yet to go off with my Stinger but have had many offs with my Evora heh

Intercooler upgrade wasn't really necessary for the track I got mine for the drag strip since I was having lots of heat soak.

Your wheels! Your wheels!

Meh most of it is just brake dust but there are some scrapes due to being dropped on the face in the driveway during wheel changes. All the damage to my stinger has happened in my driveway.

Evora - sounds like fun! Maybe someday, if I end up doing a LOT of track days.. Right now, Stinger does double duty: dropping the kids off at school / going to work and having some fun on the track (well, I plan on it, anyway). We already have 3 cars for 2 drivers, so can't really add a 4th..

Well, that's a good thing, I guess. "Meh" is not a word that attaches to any aspect of my Stinger. But clearly your enjoyment ethic includes USING the car and not worrying about attrition much.

Went out to Sonoma with Nasa Norcal on Sunday. AMAZING is all I can say. ps4s + AWD kicked ass! The R12s, my biggest fear because I've never run "race" pads, were a nothingburger. As good as my "street" pads when cold (aka 60+ degrees - love Bay Area weather!), and amazing hot. No fade I could detect. Less "ringing" than street G-Loc pads as well (I get a metallic ringing / squealing - not grinding - when backing up or lightly applying the brakes with the GS-1 pads). I may drive them permanently. Don't care if it eats up rotors a bit faster.

Last run of the day (4th session), tires were getting a bit gummed up from debris, and slipped once or twice, but MAN, the Stinger is a beast. I ran at jb4 map0 (i.e. STOCK) just to avoid overstressing it and to not overpower my abilities. map2 (I was running 91 octane) would have let me pass a few more people in the straights, but would have made the corners more tricky. Of the three: power, brakes, tires, I would say I stressed them to the limits in this order, from least to most: pads (GLoc R12s), engine (stock, drove in custom with "relaxed" throttle to get smoother, because my instructor kept complaining), tires (Pilot Sport ps4s).

Probably newbie confidence, and I know I messed up the line a LOT. But I'm definitely thinking the first thing to upgrade (if I do) is more tire. Brakes and power is plenty fine - and I could always switch to map2!

Edit: Also set the suspension to ~75/75 for both settings using the Mando ECS10. Can't really say how good of a setting that was, but it wasn't obviously bad. Car felt pretty neutral, but maybe swapping my sways around (front is hard, back soft - I think my mechanic got confused) may make it just a bit more so.

Yeah the sport throttle response can be a bit tricky especially since the car will instantly build boost and can do so at unfortunate times. Glad you enjoyed it!

For tires I'd recommend sticking with the mps4s as they are great for telling you how much you may be over driving the car but that's just me. Them picking up the bits and pieces means you were getting them hot which is what you want to a point. Were you bleeding off tire pressure before sessions if they were high? I've found the mps4s get pretty slick at high pressures and keeping them lower really helps grip.

My r10s have a real loud squealing at low speeds but silent at higher speeds which is a bit annoying at the moment but not the end of the world.

I didn't adjust pressures at all. I had the tire pressure monitor up most of the time, and the fronts went from like 38 to 40-41. I figured that wasn't enough to really matter. Ambient temps were in the low 80s with a breeze, I believe. If they had gotten over 43-44, I might have dropped a few PSI. I usually run them at 38 front, 36 rear. These are 245-40-18 in front, 285-35-18 in the rear (black Enkei TY-5s).
