I have complete spare suspension arms and knuckles, but i am somewhat unsure if they are all ap1 or ap2 parts. I am pretty sure they are all AP1. And my car is a AP2.

I was in a hurry to buy up spares getting ready for an event and just bought what i could find.

Its an endurance car, believe me, i have spares of everything!

 

Look at the space between the the arm where the lower ball joint attaches and the brake rotor. Compare left and right sides. When my car got hit at the right rear (just enough to damage the wheel and cause a spin), the alignment was off. The space from the arm to the brake rotor was noticeably smaller on the right. I don't use backing plates, so it was easy to compare the gaps. It is a good idea to know in advance what the gap is, so you can quickly judge if the knuckle got bent.

 

shifted subframe maybe?

 

i have a pile of left rear knuckles that i have bent from simply using the curbs too hard on big sticky tires. where the upper arm attaches gets bent inward away from the rotor. once you see it verse a fresh one, its easy to spot. $180 ish new from honda if your time is free, plus a 40 dollar national bearing

 

Good thinking, this will help me verify my own suspected bent front knuckle.

 

When I touched a wall in a race with 0.8g force I bent front and rear knuckles and the hubs ended up being toast as well by the end of the race weekend
