You want to get the best road balance for everyday use? Than 5100 STREET TCO SUSPENSION is a perfect option for you. Maximize grip by controlling rebound and rideheight of your car. These coilovers include springs and are designed to run OEM top mounts. 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. 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. 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. AST high pressure dampers offers additional resistance, based on the driving conditions. It will increase performance when you need it. These dampers are rebuildable, which means that if any damage or issues arise, you can have them addressed at a certified AST service center.This Part Fits:

Eh. It's fine
Color: Black
I feel like this mascara is okay. Not fantastic, not terrible. I like a dramatic lash and this mascara doesn't give me the drama. I have been using it for about a month, so I can't really speak much to how well it helps the lashes grow. I haven't noticed any difference yet. It does flake a bit, but not a lot. Really just okay.

Doesn’t flake or smudge!
Color: Black
The is the first mascara I’ve ever used that truly stays put. I’ve tried several other brands (including many with tubing effects) that advertise smudge proof but aren’t. Worth buying!

Worked Nice
Color: Black
I really like this mascara much better than I thought I would. I'm not a fan of false lashes and since my own lashes are pretty pathetic I've tried just about every mascara out there to find one that at least attempts to make it look like I've actually got lashes. I was skeptical at first but this one actually worked quite well. It has a large brush but that did a good job at really separating and drawing them out so they looked longer and fuller. I also had less issue with overshooting it onto the eye lid/brow area so less Q tip cleanup required.
I liked the mascara itself, it went on smoothly and felt nice on my lashes. It wasn't at all clumpy or cakey and was nice and light on. I also didn't have any issue with it flaking off during the day. It is a much higher price point than I typically pay for a single mascara and is not a really large tube, but I did notice I wasn't using as much of it as usual and I do like how it felt and looked on my lashes.
