Good finding.
You must love gambling big.
I recently been getting more and more questions why H&R, why not other "xyz" brand? "Xyz" brand is much cheaper and etc.
For you who also had that in mind, here are the answers.
H&R been around for about 30 years (This is about how long I have been in the Industry).
They will not use cheap material or cheap machines to make them.
And they are TUV approved, which TUV is much stricter than DOT or any US division for automotive and/or road/highway control.
While "xyz" brand, I have seen so many different news and origins of them.
Otherwise, why would I not make my own brand if I have sold over 100 sets of spacer combo just for this F15/F16 X5/X6 and F85/F86 X5M/X6M alone. Even at what OP is posting, it is still over priced.
