CV joint issues on track cars
So a few guys seem to have had issues with CV joints on lowered cars and now I'm paranoid. My BRZ is lowered slightly (Still some dead cat space between tyre and guard) with MCA Race Primes only because that's what they recommended. IDGAF about 'stance' or appearance. Anyone experienced CV joint issues with track use or is it mostly an excessive travel issue on stupidly low cars.
I have heard what I now believe to be some CV clicking, only on one very hard corner of the track as I accelerate through it. I think my suspension might be compressing too much. (I'm on 235 AO50 softs). Anyone have similar experiences? Sent from my SM-G973F using Tapatalk |

I know @rice_classic has killed some and has some good info in his T4 build thread. I haven't had an issue yet but I carry spares. Could try checking the torque on the axle nut. I had one that used to make some noise that just needed tightened. I haven't come across another twin owner that has told be about a failure on track yet.

Aftermarket axles typically fix it, as does getting a drop knuckle. |

I am lowered around 1.5 inches and have run over 25 track days with the stock axles. I recently damaged a boot and disassembled the cv joint to take a look. It had very little wear and I have no worries about re using it.
I wouldn't worry to much about them with a NA car. |

before i started taking my car to the circuit. i installed the cusco drivers side axle heat shield. simple yet effective piece where it blocks the heat coming off the exhaust by blocking the unnecessary heat into the cv joint. hopefully this will extend the life of the grease and bearing components. part was cheap and easy to install. might be a worthwhile investment if your a bit worried about your drivers side cv joint giving out.

Root cause analysis? Excessive angle= excess stress on the housing? Any warning signs? Sent from my SM-G973F using Tapatalk Last edited by Purist; 08-05-2020 at 09:00 PM. |

Im not saying cv joints never fail, but if you go to a track day virtually everyone is running stock axles and I haven't seen any cars going home on a trailer because of it. Some people on this forum have a vested interest and a history of trying to scare people into buying expensive parts from them that they don't actually need. Ive been running hard for years with no concerns and no issues until I accidentally damaged a boot while messing with the exhaust. I disassembled the joint and it looks like new, but the boot is ruined so I replaced the whole axle with a used OEM one I got off ebay for $75. It is working fine as well. |

Just because you've not had a history of failures doesn't mean everyone will mirror your experience. |

This is the CV joint after a lot of hard track miles. When I run my fingers over the wear surfaces there are no indications of wear. I may get a new boot for it and keep it as a spare just to insure I will never need it.lol. |
