Are you using your vehicle on the track? Or perhaps you’re after a combination of track performance and seeking the ideal road balance for daily driving. In that case, the 5100 CLUBRACING SUSPENSION is the perfect choice for you. This set of coilovers enables you to optimize grip by managing rebound and ride height. Springs are included and top mounts front and rear. In this set front and rear dampers utilize a coilover design. By choosing this design you prioritize adjustability and the performance of your car. Coilovers which will offer more adjustability for both damping settings and ride height, and typically provide more consistent and predictable handling characteristics. You have the flexibility to adjust springrates on these dampers. The initial setup for setting and spring rates is rooted in our extensive development and testing process. Individual preferences can easily be fine-tuned by making adjustments to the rebound knob or altering the ride height. You can adjust the rebound, means you can control the return to extension of your dampers, enabling you to attain the ideal road balance tailored to your specific requirements. With 12 distinct positions to choose from, each adjustment delivers distinct feedback and a unique driving experience. This set of suspension also includes, where applicable, camber-adjustable front Top Mounts and solid rear Top Mounts. The camber adjustment will offer you more wheel adjustment and allow this geometry to be altered to transform front -end grip. AST Suspension is a monotube design. This is a benefit for you because these dampers offer a large piston to control the adjustability of rebound damping. There is no aeration or foaming in monotube dampers, this will result in a more responsive valving. These dampers are rebuildable, which means that if any damage or issues arise, you can have them addressed at a certified AST service center.Shipping Notes

Superior product
typically take Vitamin D in large amounts to get enhanced benefits for bone strength and immune strength. this formulation includes vitamin K which enhances the absorption of calcium in your system.
These are high strength capsules with 5000 units of D in a small and easy to swallow capsule.
As with any vitamin product it takes some time for the benefits to be felt however with these products they seem to have better effectiveness than my previous brand and I find myself not having to take as much to get the full benefit.
The price is good for a premium product and the developers seem to have put a lot of thought into the formulation.

Dentist recomended
So i ordered this a while back but i wanted to use up my last bottle of D3 vitamin. I have used this smarter nutrition brand for just under a week, so it is a bit difficult to say whether this product is any better than any other brand.
But so far so good. I have no problems swallowing these pills nor any digestive problems whatsoever or any after taste.
AS far as a D3 supplement, you really feel no difference and i bring this up because i am being truly honest about this product. I started taking vitamin D3 products because my dentist, who is also a nutrionist, advised me to take this supplent for stronger bones. Also to be honest, I am 67 years young and i need all the help i can get..LOL.
I take many other nutritional products and this brand of Smart seems to have everything i need for a daily regimen. So No need to buy supplements from more than 1 supplier.
And, yes i guess i would recommend this brand to others who like to buy what they need from 1 supplier.

Good Clean Source of Vitamin D3 and K2
Size: 60 Count (Pack of 3)
I have tried several vitamin D products, some of which offered limited absorbency, so I like this product, which appears to offer better absorbency. Disclaimer: I have not followed up with testing my vitamin D levels, since I started taking this product, but I do feel more healthy, with fewer and more minor upper respiratory infections, and no flu, so far, and this product may be contributing to this. Several things I like about this product: 1) This product's D3 comes from a plant-type algae called lichen, which is a far superior source of vitamin D3, compared to lanolin, which is sourced from sheep, and used in the majority of vitamin D products on the market. 2) This supplement also includes two forms of vitamin K2 (MK-4 and MK-7). Vitamin K2 is critical in moving the body's calcium out of the soft tissues and into the bones and teeth. if you're taking Vitamin D, it's absolutely critical to also take vitamin K2. As mentioned, this supplement includes two forms of vitamin K2, which is not found in most of the other vitamin D supplements on the market. Both forms are important, so it's great that this product includes both. 3) This is a very clean product, with no harmful or inflammatory fillers. I give this product my top rating. I use this product daily, along with taking vitamin C.
