I'm installing the suspension today, including the adjustable PHR from Spohn. VERY nice piece BTW. Anyhow, the directions say it's adjusted to OE length already, but will need to be lengthened if the car is lowered. Now in the end it really doesn't matter because I'm gonna measure to get it right, but wouldn't it make sense to shorten it, not lengthen it?

 

it will have to be shorter. the rear kicks to the drivers side of the car when lowered. So shorten it up and move it over a little, just leave it stock length and then move it one you get everythign done , and remember dont thighten everything down tight unless the jack stands are under the rear end , otherwise it might bind if you did it with the stand under the body .
