Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately, it is highly recommended that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides. Dinan's Performance Spring set for the G20 M340i (RWD) and 330i provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the car for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief to last the life of the car. The increase in stiffness will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip for high-speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle. NOTE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height performance and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits. While we will maintain a full warranty on product defects any claims against the car's improper handling ride quality traits due to not purchasing the corresponding handling kit will not be warranted.

Great entertainment for kittens too!
Color: Blue
My kittens love this toy and play with it more than my dog. I bought it on sale. I am impressed with the quality, ease of use, and I rarely need to charge it.

Finally, a Toy That Out-Works My Dog!
Color: Blue
My dog gets bored easily, and this automatic moving ball has been a hilarious and effective distraction. It bounces and rotates on its own, which triggers her hunting instinct immediately. The rope chew attached to the side is a nice touch for some added teeth cleaning while she plays. It’s sturdy enough for a medium-sized dog and the fact that it's waterproof means I don't have to worry when she eventually drops it in the water bowl or takes it out into the melting snow. The *only* issue I have is it starts before I can even screw it back together. It wants to jump out of my hands before I'm ready.

My dogs think this is either terrifying or amazing
Color: Blue
I got this interactive dog toy thinking it would turn my living room into a fun little chase arena for my two small dogs. Technically, it did create excitement, but not in the way I expected. The toy rolls around unpredictably and wiggles its rope like it is trying to escape, which is honestly hilarious to watch. The movement is surprisingly energetic and the different speed modes keep it from feeling repetitive or robotic. The battery life is decent and it charges quickly, so it is easy to keep it ready for playtime.
Now for the comedy... my one year old Silky Terrier is normally the fearless one. He charges vacuum cleaners, interrogates delivery boxes, and believes he is the head of household security. However, the moment this toy turns on and starts moving, he suddenly remembers he has very important business somewhere else. He will sit at a safe distance and stare at it like it might file a police report against him.
The funny part is that when the toy is turned off, it instantly becomes his favorite object in the house. He happily grabs the rope, drags it around, chews on it, and proudly carries it like a trophy. Apparently his bravery only applies when the toy is not alive. I have discovered that in my house this is considered the acceptable mode of operation.
My seven year old Yorkie is even wiser. She took one look at the moving toy, processed the situation for approximately three seconds, and decided she would absolutely not be participating in whatever nonsense was happening on the floor. She calmly walked away and has maintained that policy ever since. She clearly understands this toy and wants no part of it.
Overall the toy is well made, entertaining, and definitely capable of keeping energetic dogs busy. Even if your dogs end up like mine and treat it as either a suspicious creature or a decorative rope toy, it still provides plenty of entertainment for the humans watching the situation unfold. If your dog enjoys chasing unpredictable moving toys, this one will probably become a household favorite. If not, you may at least get a very funny show out of it. 🐶
