I tried to find out the difference between the 28998-1 and the 28998-5 kits. It looks like -5 is "front axle up to 1160kg" and -1 is "1161kg+"
I'm guessing for any added weight between a 1.6/1.8 and the 2.0T?
Unfortunately it has been months since I did my initial research but I finally remembered why I went with the -5.... if you look at the door sticker, our front axle is 1112kg. That would mean -5
I would say worst case, -1 is a little stiffer.
Well hell...the difference between these two springs is that the 1's are rated to carry an extra 2lbs.
1kg is right around 2.2lbs...
So yeah...just as I suspected...they are basically exactly the same.
