The best value for the money i think I've ever run into! Great buy!
All parts were great! Only problem is the bag a bolts aren't labeled or anything just a bag of all the bolts wish it was with each parts
Perfect fit
Fit perfect and so far so good.
Lots of parts for the money!
Really liked this kit. Had no problems with the quality or fit of the components. For the price it was great. My only gripe was the hardware. Just one big bag of bones washers, etc. Sure most was self explanatory, but would have liked some form of identification. But once again, for the price it wad well worth it. Yes I would recommend this kit!
The entire process from 1a auto was smooth and easygoing. Ordering the parts was simple. Parts came quickly and in good condition. Installation was smooth and a direct fit. I used the YouTube videos from 1a auto which was a huge help. Overall great product, not my first time ordering from here and definitely wont be my last.
Car rides like new! Everything fit except for sway bar links but Ill just go buy the bolts that fit through the new sway bar links!
Justo lo que esperaba excelente calidad
Everything fit like the should, aside from sway bar links. Links needed to get tapped because the threads didnt go all the way through. The bolt kit had quite a few bolts that were excessively long, two had to get trimmed down for sway bar links. Bolts would bottom out in the sway bar.

The control arms are the same. The B7 uses a different tie Rod end than the B6 though, so no guarantee the tie Rod ends will fit. The suspension is the same (where the uppers mount) and the upright is the same part number for all 2002-2008 models. The control arms are interchangeable.
