Here is just a heads up of a local track friend who installed some Elephant Racing lower control arms on the front of his street/DE track prepped Cayman. After 8400 miles of mixed street and track use, this is the result of a failure of the outer monoball trunnion pin.

Several years ago he installed OEM RSR LCAs in the rear of the car and chose to go with the Elephant LCAs in the front which resulted in a failure that caused significant damage to the front fender area as the wheel broke away from the suspension and the car went off track. He was very lucky this happened on turn exit as opposed to a 100+ mph sweeper where the results could have been substantially catastrophic and potentially deadly. The RSR arms on the rear of his car are going strong without failure to this day while the result of the Elephant arms installed on the lightly loaded front of the car are shown below.

To all my track peeps, be careful out there and don't skimp on quality parts especially when your neck depends on it. No matter what parts you use, set up a maintenance internal schedule and stick with it. Cheers!

Ouch! .. anyone have similar issues with RSS ones? That's what I have in the rear.

I am running all of the RSS hard parts on my GT3 and have not had any issues with quite a bit of track time.

Much of the aftermarket stuff is a ticking time bomb on hard tracked cars in my opinion. Porsche Motorsport has gone to great lengths to beef up these high stress areas like the trunnion pins by using exotic metals like Vascomax which is a 300M vacuum remelt steel and on the 991 and later cars has gone to a double shear arrangement vs. a single shear on the 997 and prior cars. Even so, these parts are not immune to failure and should be replaced on a schedule that meets the end users needs based on use. The stress on these parts goes up steeply depending on how hard the car is driven especially if slicks are used.

Wow, thanks for the education. Never knew.

Have to rethink my suspension direction

Damn that sucks! I have the Elephant Racing rear lower toe links on my 6GT3 and have not had any issue with them so far. Hopefully with proper monitoring it stays that way!

Lets be clear
erp and elephant racing are different.

I assume you meant elephant?

a while,back rss had a rash of pin failures on their lower control arms.
