This is the MCS 1WNR coil over shock set ready for your camber plates and spring package. This is the perfect package to begin building your E9X track coil over suspension or to upgrade from your inadequate current dampers and hardware. MCS 1W are incredibly versatile with 18 truly unique damping rates. The 1W is an excellent starting point that is tame enough to use on the street even with stiff springs. The shock internals share the same components as other MCS struts so it can be upgraded to a 2W damper later. Contact us if you want us to help you complete your track coil overs!
MCS 1W coil overs are adjustable for rebound through 18 distinct and meaningful settings. What makes an MCS damper stand apart from the rest is in the shock tuning and rates. Each click has been plotted for specific rate targets and is not just an X% difference from the clicks around it. This is why an MCS shock can provide a comfortable ride on the street even with stiff springs and how it can deliver exceptional performance on even bumpy tracks. An internal blow-off valve unique to MCS also contributes to ride quality and suspension compliance even with hard impacts.
Can I run rear coil over in E9X? Yes but it comes with some drawbacks. It's definitely possible and common, however, our preference is in a divorced (separate) spring and shock. Rear coilovers require the spring to sit in the wheel well, which eats up valuable tire space. Rear E9X coilovers are likely to have clearance issues with the rest of the suspension and tire. No one has done independent extensive testing on the chassis rigidity to say the rear shock towers are properly supported for coil overs without a cage or extra reinforcement. But people do it anyway. We would rather see a divorced setup for clearance but if you run rear coil over we'd like to see additional bracing or reinforcement.
Related Items: this is a “starter package” of dampers that form the basis of a custom coil over build. You will also need:
springs (2.25", 2.5", or 60mm ID)
front camber plates (sized correctly for the MCS struts and springs)
adjustable sway bar links
Rear shocks are built as an eye-to-eye configuration and include clevis mounts at the top and bottom. However, if you have converted the rear spring arm (aka rollover strut) to M3 contact us so we can remove the lower Clevis mount from your order.
The front strut brace must be removed altogether or requires changing to the M3 strut brace. The original E9X non-M strut bracing interferes with the MCS strut pin. E82 cars require the 1M strut bracing (contact us).
We encourage your questions and inquires. We can build a package for you after consultation and cannot be compared on price alone.
