Are these rear spring? What’s the spring rate?

I believe these only go with the QA1 coilover kit from SCP. The pic shows them being 450 #s.

Correct these are for qa1 coilovers. So they will not fit in the stock location of the rear. Can fit both front and rear if running coilovers

I know they’re for the QA1’s from SCP, I’m running them in the front of my car but not the rear.

450# seems like it might be too much for the rear?
I believe that’s what I’m running in the front

Honestly bro I’m not sure don’t wanna lie to you, but I moved up to 550’s up front and I felt it controlled the wheel weight a lot better, we’re running the same wheel combo. Check SCO and see what he recommends out back. I feel like these are not enough spring out front but might be good enough in back
