I currently have d2 coils and camber plates in my car which are fairly new, so I was wondering if I would have to get rid of them completely to run bags.
You could do a bag over coil up front using the Universal Air AeroSport
bags but your ride quality and handling would be better with an actual air strut. It would be a bit less work to use your existing coils with an AeroSport bag since the struts are already set up for your e30. If you wanted to go with the Air Lift Universal struts, you would have to cut off your oem spindles and weld them to the Air Lift struts, as well as making custom top plates.
The Air Lift Universals will definitely require more work, but in the long run it would be the better option. If you just wanted to bag the car quickly and in the least expensive manner, AeroSports on your existing coilovers are a good way to go. As for the rears, you will just need to do a little fabrication with the top and bottom mounts and use the universal bags of your choice.
