If you buy the MSS kit, make sure you get it from MSS UK, with the current exchange rate it’s cheaper ( free shipping to the US ) and you can guarantee you’ll get the latest version of the kit (it's gone through a couple of revisions / short springs / long springs, etc etc).

The street standard kit is currently £495.83 which is 643 US dollars.
The fully adjustable street is currently £599.95 which is 782 US dollars.
Make sure you understand the current issue with the front springs (205 length, or 220 length) and make sure you get the right one for your needs. Currently dealing with the front spring issue right now (front spring marked MQB205 is a tad short, so when the adjuster is set at no gap, the spring swims around in there loose under droop - eq. working on your car. There's extra play and space means you gotta be real careful putting you car down as the bearing may misalign with the locator slot on the top mount leaving it cockeyed), and a lot of people dealt with the rear sport spring issue (where the front had to be at max drop, and the rear at max height in order to try to get it level leading to now adjustment options at all).
We believe the latest kits for the MK7 were revised and have 60mm ID rear height adjusters (so orange spring on top, black spring on the bottom) - nevertheless, the ones the current US dealers are selling looks like it's the old 2016 stock (black spring on top, orange spring on the bottom - 65mm ID rear adjuster)

Another option you should explore are the new 034 Dynamic+ Lowering Springs (they got a GTI and a GOLF R specific one).
Good to know, thanks! I've done some research on the 034 Dynamic+ Lowering Springs but still waiting for more people to share their experience with them.
