Good info, I will replace mine at the end of this year then. I will just add my 2 cents though because I've reused all of my bolts and have never had one break on me. I've done 13 track days since installing the lockout kit and it's been 4 months. And I reused all my bolts up front that are TTY for 2 years without issues (I replaced them after 2
years). I will check them for tightness before my next trackday. It's possible it was overtightened or that they just do need to be replaced. |

I replaced my outer toe rod bolts with some metric 10.9 flanged hex head bolts from belmetric.com. Normal non-TTY bolt that can be reused.

I suspect the SPL install directions to torque the bolt to 74 lb ft instead of 74 lb ft + 105° as mentioned in the shop manual might have caused my reused bolts to come loose over time especially since they were already stretched/yielded when originally installed with the higher torque + angle value at the factory. |

So there is no concern with the single jam bolt loosening? How often do you check them? I want to pull the trigger but am concerned about it loosening as the car does track days and street driving. If that bolt were to back out it looks as tho a catastrophic failure could happen when driving.

The blue jam bolts (on all SPL parts) that keep the ends from adjusting/falling out of the center shaft. See instructions/warnings in install instructions below. 150in lb is the recommended Tq, but no mention of re torque needs. stock parts are solid makes me wonder if its for a reason. https://www.dropbox.com/scl/fi/lpblz...qeasfpqdr&dl=0 |

Yes it's the rear toe bolt to the hub. If you have the toe arms for over a year I would recommend replacing the bolt now. I do not know if you need another alignment. I just replace it before the season starts and I get my yearly alignment.

I replaced all my TTY bolts when installing the ZLE subframe bushings but I did not replace the bolts when installing the SPL toe arms, which was a mistake, and now hearing it can break it seems like it might be a big mistake. The ARP bolts have a 180 ksi tensile strength, grade 8 is 150 ksi, so they are plenty strong but will need to be torqed normally, ARP gives a 98 ft lb spec for these bolts. In addition, I'll use some threadlocker. If nobody had an issue with the bolts breaking I'd just go OEM TTY, but if they need to be replaced annually and they are known to break, then the bolt is too close to failure for my tastes. Metric grade 10.9 will work too, they are about the same as grade 8 SAE. ARP are really well made bolts though, and at most places online buying 2 M12 bolts and shipping came out close to the 5-pack of ARPs at Summit. I had a 10% off Summit coupon and also free shipping since I also bought motor oil for the next change.

krops, does the SPL front endlinks work with MCS? Looks like you had to return a set, but can't tell if it's front or rear.
