You do you. But the expectation of a part not being good enough if you have to check up on it is ridiculous lol. |

Seeing that failure doesn't change my perception of SPL Parts nor will I change my buying habits. This is one failure on one car of which we have very little information, to tsk94's point.

There is a massive difference between 'checking all the bolts in a suspension' and passing a tech inspection.
There are many bolts attaching many things to the car. I do not check all of them before a track day |

Not having to worry about something like this failure is huge imo. And Jason isn't slow, so having some spherical bushings isn't going to make you any faster. |

Also, it looks like a sheer, not a bolt issue.

Do we have any video? Just playing devils advocate (I also have the SPL conversion and have not had issues), but that type of damage can be easily done in an impact with a wall. I know that car has a data logger so I'd be curious to see the wheel speeds and brake pressure at the time of the failure/impact. I think all this is important to share due to the amount of people who have these.
I find it odd that the tension arm would just straight up snap. There's a minimum thread per SPL that needs to be inserted into the arm, was this followed? If these were brand new, were they tightened properly, or just hand tight quarter turn? I know DJ TJ well, so I'm assuming all the answers are yes.

Talking about failure rate, do we have any other documented failures of this or is this a one time thing?

And yeah, I know lot's of people that are checking all their bolts. Is it really that uncommon and I and the others I know are out of the norm? Paint marking is your friend too. |

But that's just for the suspension arms. Apparently we need to check all the aftermarket parts. Let's tally that up real quick and see what I'm told it is 'crazy' not to check before every track day. BBK: 2 bolts for the bracket to the car, 2 bolts for the caliper onto the bracket, 2 bolts for the bridge, 4 brakes: 24 bolts I guess it would be really risky to not also check the bolts that join the iron rotor to the alu hat. 40 bolts My suspension is aftermarket. Looks like I have to check that as well. top suspension bolts: 4 bottom suspension bolts: 4 sway bar end links: 2 per wheel: 8 sway bar brackets: 8 total suspension: 24 So quick math says 152 bolts. Pretty impressed with some of you guys! |

Checking bolts before every track day is not 'bad', the same as going every day to have a medical exam is not 'bad', I just find it to be a waste of time. If a part requires constant 'checking' to operate, then it does not operate correctly. I don't know how else to say it. Somehow I have a bunch of parts on two track cars that require zero checking/rechecking before every track day and somehow, although the car is driven to/from the track, so far all is good. I don't think I'm that lucky.

My point is things should 'work'. That is my expectation. If I need to be checking on something every track day then I don't consider it 'works'. I do all the car work myself so I'm very familiar with it, but I still don't check and recheck constantly. |

Like I mentioned, I know very few FAST drivers/racers that are really pushing their cars that aren't bolt checking frequently. Hard track use loosens stuff up, end of story. Is checking 'every bolt, every time' overkill? 99% of the time it is. And I'm not checking every single bolt, as per my above comment, but I am bolt checking the car after every day. But you'll be wishing you did if some dumb preventable incident happens. If you don't want to take the time to check them on your car that's fine. |

I do too many track days to be checking bolts every time, so I run oe arms with spherical bearings. I've never liked the look of the spl arms anyways. They just look kinda sketchy to me, like they would never take a decent hit.

Well hopefully we can get some useful first hand accounts, data, video, etc.
Appreciate anyone pushing the owner/driver to make us all smarter- obviously on their own schedule. Disclosure: I've got all the SPL stuff so I'm certainly an interested party like others here.

I have a hard time believing people don't have 30 minutes extra to spare when getting ready for their next upcoming track day. And it's not like you need to do it EVERY single day, every 2nd day out is better then once or twice a season XD |

I have a quickjack and after each trackday I lift the car up, take the wheels off and look. While I don't check every bolt, I do look carefully with a flashlight to see if something does not look right. I admit to enjoy it, so perhaps not a chore.
Having say that, I always see something that needs attention. I will now add looking at the SPL setup to see if things are moving. The good news that after 3 trackdays the alignment has not budge. An improvement over the other aftermarket arms I used to have. |
