ISC How To: Set Preload + Adjust Ride Height On Divorced Rear Coilovers

This video describes how to setup coilovers on a vehicle which has a separate rear spring perch and strut design, also known as a divorced rear coilover. This video guide can assist with multiple vehicles which share this common design, such as; BMW E46, E36, 350z, 370z, S550 Mustang, Mazda 3, Ford Focus ST, + More.

This is the only video that clear shows how to set rears, thanks a million guys!

I think a better way is to install the shock without the spring first and determine the maximum amount of compression travel you can get without interference, this gives you the limitations of ride height. If you arbitrarily pick a ride height first, you could be unnecessarily compromising shock travel and the car will ride like the Honda ricer with cut springs.

So i can, without ever attaching my rear damper, roughly set my rear ride correct?!?!? Sitting still, I'm thinking the damper will not affect the ride height at all.... yay or nay???? The damper acts like a limiting strap holding a constant preload on that spring in the event that things go zero weight on that wheel during driving.

When you are adjusting the height of the shock by screwing it's lower portion - you are not mentioning what is the compression position of the shock it self? Is it mid way? Or fully extended? Or compressed?

I don't have ISC coilovers, however this is the best explanation of preload for a divorced rear spring setup common to BMW's.

What is the rear Spring ID?

[@Ivanorlando97]

Hi, how much is the preload in lb ??

[@lexmichael2040]

where you guys located at? I have a godspeed divorce set and I want it to be done properly cause It’s kinda Bouncy.

[@manusdei5148]

The rear shock. Do you turn it as much as you did on the spring adjustment or?

[@dwightdaniel8836]

Question, when adjusting /screwing the lower mount on the strut does the piston on the strut be fully extended?

Most clear tutorial yet 👍

Hell yeah thanks for this video! Nice and informative. Now I know how to set up the rear suspension on my own e36. Simple videos like this make me happy that I choose isc coilovers for my car.

[@elijah3145]

Best explanation of rears so far! Helped a lot!

[@eXiteVideoMagazine]

Thanks for explaining the rear ride height and preload!

[@bretmatthews4172]

Snapped my rear shock mount off and when I set it I was guessing but know I feel confident in setting preload and length. THANKS

[@jharleygaming7633]

Very informative, gonna readjust my coilovers tomorrow thanks

[@CW-fe8dt]

Great explanation of the rear preload and shock adjustment.

[@seh97]

Excellent video. Exactly the tutorial I needed.

[@bighomieJ5X]

[@FG2-K24A]

Just what I was looking for! Thanks for sharing 👍
