Spindles Should I replace?

[Indivisible22]

I'm trying to figure out if I should get new spindles for my 2014 Phantom Triton. I bought the kart in winter of 2022. It did not have new spindles when I bought it so not sure how many races were on them. I have not replaced them yet. I've ran about 70+ races since buying it, mainly Saturday night shows in Ducar classes. I still run up front every week and run competitive lap times with the field.
Would there be an advantage to replacing them or would I get a little faster with having new spindels? Any and all suggestions welcome.
Thanks!

If they aren't bent, replace the bearings and the king pins and keep using them

If your %'s changed or don't seem to change after cross adjustment , then yes .

70 races and haven't bent one? That is a lot of clean racing!
