the factory buckets work fine with no offset
if you were to fab upper mounts the coilovers make a lot of sense, you wouldnt have to remove buckets from the donnor or figure how to mount them to the obs
the only part of the Driven kit you need is the timer.
I trust the oil pressure switch more then an inertia switch.
the relays and fuses can be inserted in to the factory underhood fuse/relay box for a factory look.
