I have had my buggy for about a month in a half and I have only broke one upper front arm. It wasn't even fully broke either, just the front part that connects to the hing pin tore and was still working as I finished the race with it that way.

I have yet to bend any of the hing pins or the lower arms. The caster blocks seem to wear pretty quick leading to some slop in the suspension but it doesn't seem to negatively impact the way the car handles just yet so I have not replaced them.

Keep in mind I go to the track 3-4 times a week and normally run 6-10 packs each day.

I have had to replace the front shock tower due to me landing on my lid and bending it to a point where I could only mount the shocks in one of the mounting holes, and i also broke both the front and rear chassis stiffeners.

All the other parts I have replaced were due to my own mistakes while assembling the car.
