I just received my new Vogtland springs and had a look at the suspension to see what tools would be needed.

Does anyone know the size of the allen bolts(hex) on the fronts

My spring compressor should be here in time for an install this weekend.

i actually used a tuner key. A tuner key is what most hondas with wheels use for their wheel lugs. I just used the tuner key with a wrench. I didn't have an allen key big enough, so I grabbed that and it worked perfectly... PS- there are two screws on the bottom of the strut that go into the spindle, be careful when you tighten them... I learned that the hard way when I broke the head off one and left the rest of the screw in the spindle... took me an hour to take out the piece in the spindle, then another hour to find a replacement screw... I suggest you tighten these two with a ratchet by hand as tight as you can... but like i said, be careful!!! Good luck, and post pics when it's done!

spring compressers can be evil. tighten evenly. Regards, 3 finger Sam
