Hi guys,
For the large allen wrench, Take a bolt and 2 nuts, tighten/lock the 2 nuts at one end. Makes a cheap tool but it works! On the damaged bolts, I used a chizzel to knock them counter-clockwize to break them loose. Only BMW has those special bolts. I asked for a 1995 318i axle to flange bolt. Under $20.00 for all 6. Use red Locktight for the installation and tighten to 15-20 ft. #s. The front springs are tight when the car is raised up. On a friends car they are very loose when the car is raised up, about 3 inches of movement. Make sure they seated proprely when the car is lowered. I thought this could be a problem if the front end gets airborn and the spring moves from its seat. Taller springs with a lower rate maybe the fix. My friend didnt want to pursue the issue. Hope this helps.
