Gen1 949Racing Billet coaxial shock mounts. Will fit either NA or NB
I sleeved the original 12mm locator bushing bores to fit the 10mm Bilstein shafts. So will fit Bilstein shocks and should fit the Xida shafts if you remove the sleeves. These are to compensate for any misalignment of the shock shaft and upper mount as the arm swings through it's travel. I use a set on the front of my NA with MSM Bilsteins that I built up. My ride height is 4.75" to PW on the front (Dual duty spec) and I have no bottoming problems. I use FCM 36mm bump stops all around.
Also, as they originally were setup for 2.25" springs I added nylon locators so you can use the normal 2.5" ID springs.
$100 + shipping in the USA(will fit in a medium flat rate box)
