I used every method known to man to get this bolt out when I upgraded to my Neuspeed suspension. We even drilled all the way through and it still didn't budge. I had to scrap the whole strut and control arm and buy a control arm from the junk yard! The bolt on the other side was twisted so bad I had to replace it. From the dealer those bolts are $11.00 a piece plus tax! Definitely use antiseize when you can!
