SL Lowering Springs

hey any of you guys know why they list different lowering springs for the base, sl, well for the vr4 i undertand it. but my car is an SL with a electric sunroof, what in the world does the sonroof has to do with the springs??? i change the struts before and i see, not one wire that comes even close to the strut mounts or assembly..what's up with that...does any of you know why they don't have springs for the '94 and up with electric sunroof, mine's a '98.
also has anyone of you ever use royal purple??? i heard its really good.. if you have, have you use it eversince the 1st oil change, or did you had a couple of miles on the already..
well thanks and have a happy new year

95 sl with power sunroof has the VR4 electronic suspension cause thats what i have. didnt realize it till after i had bought some eibach coilovers and had them halfway installed. however made them work and i hate them so much hope this helps

Whats so bad about them? Too rough?

well, see that makes sense...electronic suspension. but i have just a regular shock and springs nothing more...there's not any buttons for the shocks or to set the damping force...
i don't know what is up that..thanks though..
i don't really want a bumpy ride..
