^^^ this, 100%.
My only commetn is I have seen real problems with the summit brand stuff - poor machine work, etc. I've been told that it's just stuff made by other companies and rebranded, but I have specific evidence for some stuff that isn't true.
stick to less than .470 lift which will just about ALWAYS fit.
