My rear end inside the fender lip to ground measurement was originally 29" and I installed Bilstein Sports at the time of lowereing. By using longer bolts, I dropped down a full 2" to 27", and this caused some bottoming out of the bushings of the Bilstein Sports when hitting a certain dip in the road at 80. (That's KPH and thank you for asking officer.) By reversing the rear shock mounting plates with 1/4" spacers under the plate to prevent the ridges from bottoming, you can pick up .705" of additional shock travel. I gained .100" additional travel by facing off the steel rings on the Bilsteins that mount the rubber shield. These allow the mounting washers and rubber donuts to slide further down the shock rod so that the rod is extended further to pick up the upper mount. With this total of .805" additional travel I do not bottom out under the same test conditions. That's the good news. The bad news is the tire will slightly rub the top of the fender well when this happens. It's not too bad provided I don't do this every day, but does establish a limit as to how far the car can be lowered with these components. Additional shock travel could have been obtained by grinding down the mounting plate ridges and using thinner shims and or elongating the lower mounting holes and welding washers, but this would tend to let the wheels come up further when hitting a bump; not a good thing if the tire O.D. is going to rub the fender well. :cheers:
