so the H&Rs are just too low for my taste, I'm looking to switch it up and raise it up a tad. I have 19" coupe sport wheels and was wondering if I should go with the IMPUL springs that I already have in the box or with SWIFT. I believe the SWIFTs are new and haven't really read or seen too much on them. this is for 2007 G35X

 

in my opinion and what I have seen, I dont think you will be happy with the Impul drop. If you are going IMPUL you might as well do the 370z spring with rear springmount cut. Swift drop was perfect for DDing although ride was a little rough.
