either extend the wires yourself, or spend the money on extenders. Ive extended many O2's this way. If you have a predator, then turn the MIL off that way.
when we put on the MM ones, we just set them up near the middle of all the adjustments and its almost always dead on. But take it to an alignment shop after you put them on.
If you want to just lower it enough to make it look goodand handle even better, then go with eibach prokit. H & R supersports if you want it lower, but you will need other stuff with this kit.
get the M/M ones. They are the best ones IMO and have very good instructions and support. I have done quite a few of these, so if you have any questions, then let me know
a good tune will keep you from blowing up, but it probably will happen over time. Forged crank, pistons, rods, bearings, oil pump, rings, and gaskets. Figure about $3K for everything.
