so i have an 02 civic si. I have a K20a2 swap I wanna know whether the base rsx axles would work?

 

If you are meaning, because it's a 4 lug would it matter with an a2 swap and the base rsx axles, i don't think it would matter as people who do a 5 lug conversion don't really change their axles anyways. So my guess is yes it would work with base rsx axles or your stock axles from the 02civic si. But that's only speculation.
