how about some intercooler mods even if you have no engine mods, sounds like a good idea.
On the other hand, I wonder how much of those aftermarket suspension parts do good other than claim, something like the trailing arms and tie-rods, if they claim to fix wheel hop you arent getting any wheel hop on a roadcourse so what are the benefits, and since those were developed on the SS how much different is the ZL1, does it still need those mods?
Going by the if its not broke dont fix it approach.
