The BimmerWorld View - We can't say enough about the tremendous value of this E60 525i/528i/530i/535i track suspension, which gets you a complete coil over shock, spring, and mount kit with track-ready specs right out of the box. While this won't put you on the podium in competitive club racing, the ISC Track coil overs are an excellent option for beginners or experienced drivers who recognize the limits of the Sport coil overs and don't want to break their wallets climbing the performance ladder.
The ISC coil over kit includes:
- Track-spec springs
- Front and rear dampers
- Adjustable front camber plates with spherical bearings
- Rear shock mounts with spherical bearings
The springs used in this kit are typical for track cars used in HPDE or open track events but softer than what we prefer for an all-out competition car. The kit comes standard with 672 lb/in and 672 lb/in 2.5-inch springs (12 kg/mm front and 12 kg/mm rear). We feel that this is a solid base spring rate especially for cars that still see limited street use. ISC uses industry-standard 2.5-inch springs so stiffer springs are available that fall within the range of the damper's ability.
ISC uses monotube dampers with 32 positions for compression and rebound (not independently adjusted). Shock damping curves have been set by ISC specifically for the springs in the Track coil over kit. With these shock adjustments and spring rates you can have a car that is moderately comfortable on the street but still hugely capable on the track. And unlike many other 'club sport' kits, the ISC dampers can be serviced and rebuilt in the USA. From our testing, the ISC Suspension greatly reduces bodyroll, eases weight transfer, and produces razor-sharp handling.
Solid mounts are included with adjustable camber plates in the front and spherical bearing rear shock mounts. Each damper is separate from the shock/strut housing - ride height is adjusted through the body of the shock not the spring. Most other coil overs preload the spring which reduces travel before coil bind. With ISC coil overs, the major ride height is set in the shock body reserving the spring collar for small adjustments. All pieces are either powdercoated or anodized for corrosion protection.
ISC has a 5 warranty on all components except consumables. 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 Track Coilover Package for your E60 525i/528i/530i/535i 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.
This suspension package comes complete with springs, dampers, front camber plates, and rear shock mounts - a huge value! We stock, and highly recommend, the street/track mid-range springs that we spec with ISC - 12 kg/mm front and 12 kg/mm rear (672 lb/in and 672 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.
This suspension kit includes a Five-Year Warranty
that is serviced in the US.
