I'd be curious to try other shocks, but the fact that the fronts are such a PITA to remove will keep me satisfied with the stock Z06 shocks for a while.

Does anyone have any good tips, other than the tie wrap method, to remove them?

Some people loosen the A-arm bolts to ease the shock out. While doing that may not affect the alignment, I didn't want to risk that.

Z06 Shocks

I switched to Z06 shocks on my 2009 C6 Z51 manual transmission car to get rid of wheel hop during drag racing. The wheel hop occurred with both Nitto and BFG drag radials at various tire pressures. I read on this forum that the Z06 shocks helped. Bought a set from GM Parts Direct

and installed them. Problem solved

On the Z06, the factory shocks are subject to wheel hop and have too much rebound so they are twitchy over bumps. Many Z06 owners have gone to Bilstein Sports $300, DRM Bilsteins $450 or Phadt Johnny O'C, a little more , to get rid of the twitchy back end. Maybe the added 70HP makes the difference but LS2-3 motors with a little work can be up in the stock Z06 HP range.

My Bilstein Sports got rid of the twitchy back end and I have had wheel hop only very briefly on the 1-2 shift on one pass (of 11) at the Mojave Mile (173.5 MPH trap). I am very happy with this $300 replacement.

I have to say as a Z06 owner that bump steer is a problem with the oem equipment. I am currently looking to upgrade to Johnny O. shocks and possibly sway bars too.

Not to split hairs here, but an important point is that while the Johnny O'Connell shocks are built by Sachs, they are valved specifically to our specification after track and street testing with Johnny. They don't really have a whole lot in common with the Sachs Z06 or the Sachs Z51 shocks other than being built into the same bodies. The damping between our Johnny O'Connell shocks and the Sachs OEM parts are very different... overall they are closer in performance goals to the Z06 shocks than Z51, but the way they go about achieving those goals is different.
