H&R is some of the finest suspension components on the market!!!!!!! Who ever said Drop Zone is good obviously doesn't know much about suspension, they are JUNK!
You can't beat H&R's german over-engineering, quality, price, etc.
If it's not name brand & cheap then it's junk especially when it comes to suspension.
There are 3 brands of springs I recommend H&R, Eibach, or Neuspeed.
Your installing good struts so dont ruin it with crap springs!
