I love this thread hahahaha.
OP, listen here, because apparently you don't understand this like even a little bit.
SPRINGS COMPRESS TO DIFFERENT HEIGHTS. An 8 1/2 length spring may compress to 5 inches when under a certain weight, while an 8in spring may only compress to 7inches under that same weight.
Now please, don't act like the previous idiot you have been and UNDERSTAND WHAT WE'RE TRYING TO TELL YOU. GOSH.
Do a tradsies and you'll be set. Or continue to think we're assholes because you don't know what you're talking about.
