yeah, a lithium jump pack has come in handy a few times especially when using small battery

 

Seriously? Do you run leaded gas? I've literally never changed front 02 sensors out on my cars.

 

ABA worm clamps are better

 

Thanks for all the responses, which are really helpful, even though now I'm afraid to go back to the track!

Is there a concern with the coolant overflow, other than having it overfull? Mine goes higher than usual at the track after I park it, but no where near overflowing.

I have never replaced my front O2 either and I easily have dozens of track days on it. It did put heat shielding around it though and my O2 is coated.

For wheel bearings, do they usually wobble when they need replacing, or are they great until they come apart?

Please keep the responses coming!

 

So, no one has had suspension bolts loosen up? Sounds like the vast majority of issues have been engine and wheel bearings?

 

I've been searching for a good set. Expensive, though. More than t-clamps..

OP: a lot of the issues we've listed aren't common, just possible problems.
I've never had suspension components come loose, coolant overflow, battery die, O2 sensor go bad etc. Not to say it's not possible, because it obviously is. LOL. I just don't hear that happening a lot, though all the people I track with drive moderately-tuned cars, nothing too extreme.

I mentioned the clamps/ic couplings popping loose because it seems to be common.

Our cars are pretty solid. Unless you are making 500+whp, you are fine. Don't have stress and go have fun!


P.S. 130k on wheel bearings. I run 255 wide, 100-200tw tires, so again: nothing too extreme.

i have seen strut bolt to knuckle on the front come lose, but not on my car.

you will hear wheel bearing when they start to go bad, hopefully before catastrophic failure. but i have seen complete hub failure and wheels breaking off. these guys do a lot of track and run on rcomp tires. you will hear a howling sound during cornering, that means wheel bearings starting to go bad. it's usually the left rear, if you do a lot of clockwise track. i have replace the left rear twice and the fronts only once.

 

I have saved several cars at the track with all the spare silicon couplers I carry. It seems like always the cheap/simple **** breaks.

Speaking of couplers, anyone use these Vanjan clamps? I kinda wanna replace all my silicone hoses with them (wiggins cost to much, these aint cheap either though)






Anyone ever lose an axle? I want to hunt some down for my track spare box.

 

i've only heard of axle breaking at autox during launch or drag strip.

i put heat wrap around the turbo outlet coupler, since its so close to the downpipe, the heat could weaken them. i've had one fail at that spot before i put heat wrap on it. i just use gold foil tape because i had that laying around.

 

Maybe it's the cheap $50 sensors instead of an OEM one? This last one has done 3 track days, so I guess we'll see.

 

Those should be fine, though. I get mine from Rock Auto. I think they are Denso, but I could be wrong.

 

Idk, I don't run leaded fuel. I do run Torco octane booster when I run pump gas on the street. Maybe that does it, and it just happens that the sensor fails shortly after track days.

 

Hm.... maybe that "orange stuff"? I used to run it during track days and autocrossess when I was on pump gas, also. That was not very often and I ran a lot, without it, in between. I wonder if that's what it is.

 

we use these clamps after having a couple hillclimb runs ruined due to blown off couplers.

super easy to use - seal great and no chance of blowing off. then use vband for most connections.

we pack spare axles just in case.

 

West Marine carries them. It just so happens there is one two blocks from me. The perks of living on an island I guess.

That could do it.
