Common part failures on track

[Arizona Vipers]

I'm headed to Nebraska for https://www.viperrendezvous.com/ in a few weeks. It's a long drive for me. Would suck to break something on Friday before I can get a fast time down during the weekend. If you have had a part failure on track in a Gen 5, what was it? Any sensors, parts, etc. I'll try to get these added to my trailer. Please don't mention burnt wiring as we all know about that and mine are all wrapped up. Thanks!

In the Comp Coupe I carry Fluids, extra Transmission, Jack Stands, Extra Brake Fluid,
Rotors can crack, brake pads, Hubs, If you can bring spare motor. Thats a start....AZV you
are a racer....Just bring what you always take to the track. Who knows maybe some vendors will
be there with extra parts...

Good stuff, where can you get better quality wires & serpentine belt ? The hub is the spindle aka upright ? I get brakes from porter field, good quality, low prices. What are some strong light wheels for track ?

What you suggest for a 1 piece carbon race seat ?

burnt wiring. No just busting your balls although that did happen with my Gen 4 ACR even with insulation while at Nebraska. Lugs can break especially when you are changing tires when they are still hot. The studs are a pain to change at the track without removing the hub. The right Dodge tool helps to push out the broken stud. Got to remember to bring mine. Maybe just bring a couple of spare hubs front and rear and the metal gaskets that go between them and the spindles. I've had a SS brake line start to leak. Bring a code reader. Spare brake pads and rotors. Also oil, brake fluid, brake bleeder kit. Spare nuts and bolts in various sizes. Soldering iron, wire kit, Mothers R3 Race Rubber Remover. Towels, window cleaner, ebrake pads (if you still have them), extra tires, 200 mph tape, fuses in various sizes.

I've actually got way too much insulation wrap at this point, probably 20 lbs all added up. I need to go through and get rid of where I can clearly see it's not needed. But burnt wiring has indeed ruined a couple track weekends for me hehe.

I saw a Gen V ACR absolutely destroy a set of front tires in no time at all a few years ago. I was surprised how many guys brought extra sets with them.

I'm bringing 4 sets

Racing we go thru a set of tires per hour. Good thing they’re cheaper than road tires

Cam Bolts on the timing gear, spare timing gear, extra crank with timing gear, timing chain, at least 10 new pistons, complete set of valves. Oh, and a pair of jessel rockers if you don't have those already.

Make your self some good luck. Go over the entire car first, Nut bolt, change all fluids, bleed brakes , new belt, new brakes or new pads at least, tires, visual check wheels for cracks. Inventory all the tools used to do all this work and make sure they are in your war wagon or trailer. You have raced your car enough just go back over your race notes and look for failures or problems you had in the past and prep for those also. You should have all the basics in your trailer already I imagine?. Nebraska isnt BFE either . Dirt tracks, and dirt track shops are in every town so universal race parts and and fellow racers ready to help in a jam are plentiful.

This tread got off track fast, I know what to bring to the race track, I was just wondering if anyone has had any specific failures on the track. The only one I have had all these years that I can remember was the PCM. Nothing else has broke. I've got rotors and pads etc.

Oil Pressure Sensor seems to be a culprit over the years

[09 ACR]

The only thing i have had go bad at the track is a ABS speed sensor. mine was the right rear. when they go out you are done when your abs does not work when you touch the brake they lock up.

Yup, not only lose ABS you also lose front to rear proportioning. Makes the next corner EXCITING!

[sharmut]

The only item I can think of would be a serpentine belt.

Bring a primary and secondary O2 sensor. This is my fifth year at Hastings. I always carry a pair in my trailer. 2 years ago I needed a primary, Original just died no obvious reason. Last year a fellow competitor needed one. I was a hero in his mind as it saved his weekend. I have Gen 3 ignition wire set and a Gen 4-5 Wire set along with a complete car set of ABS Sensors. I also carry a Gen 3 Throttle cable.

[q8blueviper]

O2 sensors, especially the upstream one.

You don’t wanna see the car goes to limp mode on a track day.

[Policy Limits]

Check Ball Joints for play & alignment. I tracked my GTS hard once and think they might have been effected.

[Scot@Prefix]

Arizonas car doesnt have any 02 sensors!

[sadil]

Don’t you need the front O2s for A/F feedback?

[Scot@Prefix]

Nope

[Steve M]

Don’t you need the front O2s for A/F feedback?

Only if you care about running in closed loop. They are narrow band O2 sensors, so they only work at stoich.

I'm sure they also found that running a cam with large amounts of overlap along with O2 sensors farther downstream than you'd really want them for proper operation sent them this direction. Cars ran open loop for decades, but it was before people cared about things like emissions and gas mileage.

3 ounces gone with wiring!

[ViperNC]

Ok I can't resist... Bring the following:

1. Crystal ball so you know what will break ahead of time
2. Spare race car
3. Lots of beer

Just kidding. Hope you have a great time and wish I could pull of that trip. I have to live vicariously until my girls are out of the house and off to college (only 7 more years to go).

AZ, call Dan Cragin, he's supporting a 1/2 dozen G5's that regularly track.
