Front end lowering problem
Hello all, I'm having trouble performing the standard C5 lowering procedure. I've found the threads on how to turn the stock bolts counter-clockwise and all but the trouble I'm having is that the bolts will not turn at all. I've tried shooting the area around the spring with PB and this bolt still will not turn (yes I am going counter-clockwise). It seems as though it's frozen. Any tips on how to get it loose? Thanks a lot.

Allow the penetrating fluid to remain at least overnight. Be patient and allow it to do its job. Fill the little trough on top of the spring that surrounds the adjustment bolt with the fluid. When you see that it's depleted and seeping down below the spring, it should be lubricated enough to adjust. Mine were capable of being turned without a wrench.
Another problem may be that the rubber bushing has vulcanized to the control arm. Use more PB BLASTER with a metal putty to loosen it.
Some people have unfortunately discovered their adjustment bolts are rusted solid within the spring insert. If you attempt to force it you may break the inserts bond with the composite spring. If you chose to use heat as suggested, be very careful. If all this fails, maybe it's time for a new spring...

Thanks everyone for the advice. I'll use the PB in the locations suggested and give it time to set. If I still have problems it's time for new springs ... Excellent excuse for a set of T1s lol. Thanks again.

This is what worked for me. Push that putty blade under the bushing.
