Sorry guys for being a pain but could anyone just confirm or explain to me how lowering is calculated. From speaking with someone I was told that a lowering spring with a 35mm drop is compared against a stock golf. I.E A standard golf would be lowered 35mm whereas a GTI which may already be 30mm lower than stock would only drop by 5mm with the same spring. Does this mean to drop a GTI by say 15mm a spring with at least 50mm would be required? . Tried looking the information up online but cannot seem to find an answer.
