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.

Best dog frisbee ever!
Pattern Name: Assorted, Size: Pack of 1
These frisbees are the best. We have had these for several years now they have been through countless catches, tug of war, being peed on (ew), and left out in the blazing sun, freezing cold, snow, ice, and rain. They are faded, yes, but they are perfectly intact without even a loose stitch. The design of them is different from others and the fabric of the frisbee has a slight parachute effect that gives your dog just a tiny bit more time to get those long throws. I would buy them again, but the three we have are still going strong.

Hyper Pet Tennis Balls for Dogs: Because Every Dog Deserves to Play Fetch Like a Pro
Color: Green, Size: Regular 2.5" - 12 Pack
If your dog had a bucket list, fetching tennis balls would probably be near the top. And if that’s the case, then the Hyper Pet Tennis Balls are their VIP ticket to Fetch World. These little balls of joy are the real deal, perfect for small breeds that are living their best life chasing after something that probably doesn’t need to be chased but is just so throwable.
The 12-pack means you can never lose a ball again...unless, of course, it gets lost in a mysterious “dog dimension” where all the socks go. These 2.5-inch tennis balls are the right size for those dogs that aren’t quite large enough to play with the big leagues. Think of them as the perfectly sized appetizer for the full-on Fetch Feast. Plus, they’re made from non-toxic material, so your pup can gnaw on them all day without worrying about a tummy ache (unless they’re overzealous and gobble up the whole ball...don’t worry, I won’t judge).
If your dog doesn’t love fetch yet, they will after these balls come into their life. They’re designed to be durable enough for constant chomping while still offering that classic “bounce, roll, and fetch” action that gets dogs going.
Pros:
• 12 balls = endless fetch sessions (until the dog gets tired, but let’s be honest, that’s probably never).
• Perfect size for small breeds—no choking hazards, just good ol’ fun.
• Non-toxic materials for guilt-free playtime.
• They squeak. And we all know that squeak is like doggy kryptonite.
• Durability means no more fetching balls that break after three tosses (we’ve all been there).
Cons:
• They might not hold up as well with very heavy chewers (but don’t worry, your dog won’t know the difference until they’ve already swallowed half of one).
• They don’t come in tennis-ball-flavor. If they did, I think we’d all be out of a job.
If you’re looking to upgrade your dog’s fetch game (or just keep them entertained while you catch up on your own Netflix binging), these Hyper Pet Tennis Balls are a solid choice. Plus, your dog will be too busy fetching to judge your questionable snack choices.

Prefect for smaller dogs to play
Color: Green, Size: MINI 1.75" - 12 Pack
The only balls my sato mix will fetch! They are a bit smaller than regular balls and are more comfortable in my dogs smaller mouth (she is about 20 lbs). Great bounce and durability, highly recommend!

Perfect Size - No Squeakers (yay)
Color: Pink, Size: MINI 1.75" - 4 Pack
My 9 lb. Chi-Mix adores her little toy balls. Perfect for her small size (or a medium dog) and full of bounce. I didn't want squeakers because I knew it would drive me nuts. No squeakers in these balls. Perfect training tool to teach fetch. Perfect toys to have play time with your pooch.

Nice and bright
Color: Orange, Size: MINI 1.75" - 4 Pack
These are great to fit the ball shooter I use with my dogs. Color orange makes it easy to find in grass or dirt. Problem is I have a chewer. He loves to chew on the ball and eat the orange fiber. So, the balls get wrecked and I have to replace. Gets costly. I wish they made this same size ball without the orange furry tennis-ball like covering. Maybe the toys would last longer.
