Install review of ISC N1 coilovers for E46 M3
Track review and some video in post 8
I wanted to do a review of both the install and the set up now that I've had a few days to drive on them and got an alignment. I had 145,000 miles on my oem shocks and have been doing increasingly frequent track days and am getting to a point where I can tell the factory shocks are limiting my development and don't want one to blow out in a corner resulting in stuffing my car. The decision came down to Bilstein HD or these. These won due to the added benefits of adjustments and ride height control. Disclaimer: I'm not including what size ratchets you need or lb/tq for spec because I didn't write it all down and should be obvious for sizing tools and torque specs are out there. Nor is this write up the end all or be all of how to install this system.
First of all, here's where you get the system: http://store.bimmerworld.com/isc-n1-coilover-suspension-package-p1835.aspx currently on sale for $949.99 what a deal!
Second, while the system is very in-expensive and entry level, there's a reason Bimmerworld sells them and that as of now 3 of the shop employees have them on their cars. It's tremendous value and includes the camber plates and rear shock mounts. I sprung for the rear shock adjustor extension as well.
Here is what you get when UPS drops off the box at your front door.
The front shocks come pre-assembled so you don't have to worry about assembling them, everything you see is straight out of the box. It includes the tools to adjust ride height and 4 allen wrenches to adjust the shocks on top too. The rear shocks are 2 piece as you see the shock body and bottom where it bolts to the spindle screw together as I'll go over in the install. And it includes the sway bar linkage.
