Hmmm..seems my post from earlier today didn't work out. QA1 has changed their part numbers in the past year. The "popular" QA1 shocks on this site are the following:
DS402 - Single Adjustable Shock
DD402- Double Adjustable Shock
They use 2.5" springs, and you'll find that the spring interferes with both the stock shock mount and the CV Joint. Best solutions (IMHO) are to make new lower shock mounts and use Motorsport CV Boots. For the motorsport Boots I used GKN part number MSJ6002 (Type1 CVs):
For the lower shock mounts, I'd go with something fully custom build/welded as opposed to modding the factory mounts. I started with modding the factory mounts and so much is cut away its arguably not strong enough or safe.
