So what are the advantages and disadvantages of mounting the anti-roll bar assembly top mounted or in the trunk? i wanted it up topside so i can get the ride height the way i wanted it . But are there any disadvantages to that ? i guess besides taking up trunk space for groceries .....lol

Meh, top (frame) vs bottom (rear housing) mounting of the main ARB structure IMO is pretty much the same regarding which way "works better". But packaging everything in there can be a different story top vs bottom. Bottom mounting can sometimes give you the widest possible ARB structure because of not having to fit the main structure inside/between the frame rails. But some people say ARB width isn't important if you use a big enough OD tube for the ARB. Bottom mounting can sometimes cause problems packaging the strut rods/link rods depending on the direction you point the ARB arms. Point the arms forward and the 4-link might be in the way, point the arms to the rear and the shocks might be in the way.

Top mounting can cause packaging problems on stock suspension cars depending on ride height choices. And can also create leveraging/geometry problems if the ride height choices require a real short strut rod/link rod length to get it in there. Trunk mounting a "top mount" ARB does help a bunch if space under the car was in short supply. You just have to make sure the rear cage bars/structure is strong enough & triangulated properly where the main ARB structure is mounted.

With either mounting method (top vs bottom) you also need the think about strut rod/link rod length vs OD tubing used for the links. If either method requires real long strut/link rod lengths then you might have to increase the tube OD & rod-end size a given amount as the link lengths get longer & longer.

We just wanted to get the ride height looking good and tuck the tire in the fender. So the only way to accomplish that was to go top mount. Pictures are not good , but here they are.
