No Revalves Necessary
The ultra wide range of adjustment offered by the CFD piston allows for the convenience of tuning your suspension without having to revalve your dampers. A conventional shock absorber can withstand a 2kg spring rate difference before requiring a revalve, whereas the Concave Flow Digressive Technology has a broad range of 8kg spring rates. This is invaluable for tuning your suspension quickly at the track on race day.
Jekyll and Hyde
The Concave Flow Digressive Piston allows for a Jekyll and Hyde personality. Lower spring rates can be stiffened up by using the wide damping range as an artificial spring rate, while higher spring rates feel much smoother. The large adjustment range contributes to a comfortable ride on the street and unyielding performance on the track, all with the twist of a single adjustment knob.
520 Series Coilovers are custom, hand-built to order. Most applications have a 4-7 week lead time. Lead times for certain applications and peak season orders may vary.

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
