ISC V2 N1 Street Sport Coil Over Kit - E30 318i/325e/325i/M3 Late (51mm Strut)

The BimmerWorld View - We can't say enough about the tremendous value of this suspension package, which is perfect for both a nice handling improvement, as well as getting the right look for your BMW - without beating up your wallet in the process! There is a reason that this kit is on multiple cars in our employee lot. Solid parts with a nice price.

The ISC N1 Coilover Package for your E30 3-Series, including M3, is low on price, but big on features and quality. The fully adjustable suspension includes dampers with 32-adjustment levels to cover a wide range - from a reasonable street ride to a more aggressive performance ride. From our testing, the ISC Suspension provides a crisp feel and responsive handling. For the E30 fitment, the ISC front strut tube needs to be welded to a stock spindle. Professional installation is required.

This suspension package comes complete with springs, dampers, front camber plates, and rear shock mounts - a huge value! This is a "cut-a-strut" design where the ISC coil over sleeve fits over a modified stock strut housing (cutting and welding is required). We stock, and highly recommend, the street/track mid-range springs that we spec with ISC - 10 kg/mm front and 9 kg/mm rear (560 lb/in and 504 lb/in, respectively). We feel that this is the best spring rate for an excellent level of performance while still within the range of the dampers ability to control comfortably.

Rear shock mount reinforcements should be ordered and installed at the same time (see link below).

This suspension kit includes a limited lifetime warranty with service in the US.
