Its time to do a Tech session on adjusting BC Coilovers for the 95-99 Neon, 00-05 neon, 03-05 SRT-4, 05+ Cobalt, and 08+ Caliber SRT4.
Pictured here, is a set of 03-05 Dodge SRT-4 BC coilovers.
Installing, and setting up BC Coilovers should be done in four steps. First off, Installation, then Adjusting Heigth, Rebound and Compression adjustment, and Alignment. We highly recommend installing the coilovers in this order to make sure the coilovers are perfectly setup and tested before alignment. The reason for this, is that if you install the coilovers, get the heigth, rebound/ compression adjusted, aligment done and then have a tire rub against the fender youll have to do the aligment again after making adjustments.
Installing– Installing the coilovers should be pretty straightforward, remove the entire strut/spring assembly as a whole, and then install the coilover assembly. Its a little more difficult for the 05+ Cobalt owners on the rear because the shock and spring are seperate, and the shock is harder to access.
Adjusting heigth– When adjusting the heigth, youll be working with the components in the photo below. Here you see the upper two locking rings that secure the spring perch, and the lower hub joint locking ring.(All three pieces that are discussed are the gold anodized pieces in the photo below)
Now, for most of you out there, youll only need to work with the lower hub locking ring when making adjustments. In order to make a heigth change, you should loosen the hub locking ring counter clockwise. Then, because the upper coilover assembly will spin in the strut mount, you can then thread the coilover up or down and make the overall coilover taller, or shorter to your liking. You DO NOT HAVE TO REMOVE THE COILOVER OFF THE WHEEL HUB TO MAKE A HEIGHT ADJUSTMENT! Then, after you make the adjustment, put the wheel onto the hub, lower the car and check the heigth. Make changes again to the heigth if neccesary, and then lastly lock down the hub locking ring.
Alignment– After you get the heigth adjusted to your liking, and your sure you wont make any further changes, then you should get an aligment. If you do not get an alignment, severe tire wear, weird tracking issues (car tracking to left or right) among other issues can happen.
Adjusting for Rebound and Compression– After everything is setup to your liking, its time to adjust the rebound and compression of the coilover. These are setup for 0-30 point adjustments, 0 being full soft, and 30 being full hard. 0 setting is at full left, 30 setting is at full right. Most of our customers find that a setting of 6-10 being best for street driving, 12-15 for competition use.
We hope youve found this tech issue useful !
