C3 or C4 system will work. C4 will run a couple hundred more and you get wireless. C3 will work just fine. I got one for just under 600 (that included buying a used dell to run it).hi i was wondering how much that star c4 cost?
also on my 2003 sl, been working on abc system. the rear shocks are so high
and when run it they seem like there locked in that position. any ideas
thanks, crankie frankie fp4416
If you are going to be working on your ABC system it is a must have. If your rear shocks are high and don't move then you have something going on. SDS is needed to check out if they calibrations are correct and the height sensors are reading correctly. You can also adjust the settings with SDS as well.
