034Motorsport is proud to offer our Billet Aluminum X-Brace Chassis Reinforcement Upgrade for the B8 & B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5, and Allroad! The factory Audi front subframe brace is manufactured from multiple pieces of stamped steel, and allows for performance-hindering chassis flex under load. This torsional flex can result in improper suspension geometry and alignment when cornering, and leads to vague steering feel and lack of steering precision.

The 034Motorsport X-Brace is a billet aluminum chassis reinforcement to replace the factory front subframe brace to increase torsional rigidity, resulting in improved steering feel and handling performance. Machined in-house from T6-6061 billet aluminum, the 034Motorsport X-Brace is engineered to outperform the stock welded, stamped steel part and ensure that suspension geometry is not compromised by chassis flex under hard cornering. Weighing in at 8.2 pounds versus 7.8 pounds for the factory stamped steel part, the X-Brace adds significant strength and rigidity with a negligible effect on weight.

This chassis brace upgrade was thoroughly tested by 034Motorsport and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.

  • T6-6061 Billet Aluminum Construction
  • CNC-Machined In-House
  • Clear Anodized Finish for Durability
  • Engineered to Replace Factory Front Subframe Brace

When they said strong...
...they weren't kidding. Our pup would chew through everything she could get her sharks teeth into. Like my arms. Nothing lasted as long as a week or maybe two. But she has had Dino for months now. She loves him. He is the go to toy for when she wants to play tug. The material used to make this toy is every bit as strong as the seller claims. I will definitely buy from them again. And I will not wait for this one to rip. I may be waiting a long time. If your pup likes to tear stuff apart, feel safe in buying this toy, UPDATE: 2/9/2023 Dino finally succumbed to the torture. His back ripped open and despite trying to repair him with ordinary thread he couldn't withstand the pressure, His stuffing was removed and spread all over the living room. Completely emptied he is still a good toy. Strong enough to withstand the forceful play of tug-o-war. Only thing I would suggest is to use something stronger when closing his back. The rest of him is great. I will be replacing him soon.

Not so tough
Size: Mini, Color: Gator (Pink)
I bought this because I dog sit. The dog chews up every. Single. Toy. So I bought it since it was cheap and it can be in the “chunk” (the dog’s name) toy box. It is not durable at all. He tore it up just as fast as a cheaply made toy. Chunk LOVES it! He would not stop playing with it. He loves the squeakers, it is a perfect size for him to throw it up in the air and chase it, and he loved ripping the legs off. It is good for my husband and I because there is little to no fluff. However, it is the perfect size to drop behind the couch and not be able to get. So once he drops it behind the couch, he won’t get it until morning. Now for my dog’s rating. My dog loves this toy too. He is much more gentle with toys (he has $5 Walmart toys we bought him back in 2020 in perfect condition that he plays with them every day). Before Chunk came over for the weekend, my dog Ted played with this. Ted is a larger small dog and chunk is a smaller small dog. And it is still the perfect size for both dogs.

Tough
Size: Large, Color: Dinos Frills (Pink)
Tough dog toy that's held up through multiple washes! My dogs love the squeaker. They are not destructive chewers so I can't really say how it would hold up with that kind of dog though.

Squeaker inside toy breaks after 2 days
Size: Mini, Color: Gator (Pink)
Bought for my 8 lb chihuahua for Christmas. I have 3 little girls. The youngest loves her toys and of course she took this one over immediately. She just loved everything about it. The material on the gator is amazingly durable and I believe would hold up for a good while. The squeaker inside the toy however, broke after 2 days of my girl playing with it. It's now a noiseless toy that she does not like too much as it does not squeak because it only had the one squeaker in it. I would recommend that 2 squeakers be inserted into this gator. I would not purchase again due to the longevity of the squeaker...only lasted 2 days.
