Installation Instructions:

Please Note: The use of this rear subframe reinforcement bracket is required when using an upgraded sway bar on B4/B5 chassis Quattro vehicles. The rear subframe is prone to cracking with an upgraded sway bar, and will likely crack if you attempt to use this sway bar without subframe reinforcements. If you do not already have a subframe reinforcement kit, you must purchase the 034Motorsport Billet Rear Subframe Reinforcement Bracket. This subframe reinforcement kit fits Quattro vehicles only.

Extremely thin material.
Size: 34W x 32L, Color: Midnight Selvedge
Really thin material. For the price I was expecting something closer to a buck mason quality fabric but these jeans are extremely light weight and I don’t expect them to last.

Denim feels thin but soft
Size: 32W x 32L, Color: All My Days Selvedge
The denim seems thinner than from years ago. 100% cotton feels soft. Fit me same as other stretchy 505 that are made with elastine. Waist size is fine. Haven't washed them yet. Yes, the price is high, but I like the 100% cotton and will likely buy more selvedge jeans.

100 cotton
Size: 33W x 32L, Color: Midnight Selvedge
These are great, just keep in mind that 100% cotton is not the same as 99 cotton 1 elastane, so size up if you tend to be in between mesures at waist.
