No matter what the OEM builds, there will always be owners that want more. Who could want more than a Ferrari delivers from the factory? Hmmm, Ferrari owners. |

I have little doubt these will help performance. I'm definately still going through all the bushings and go poly all the way around, and figured the sway bars are probably another addition I'll be making. As far a tearing the lower mounts - I've been considering arms, too, anyways, so that's not as big a deal. I've just been worrying about claims that the MRC III won't take to modifications too well. I've been assuming that because it's active, it will probably compansate enough that smaller mods', like these, wouldn't be a problem, so I'm interested to see your cars' results

BTW - Pete.
I haven't checked, but have to revised, or planning to revise your Suspension Book for ZL1 (and eventually 1LE)? Thanks

Just as the MR and PTM is best tuned for the stock tires I find it hard to believe it would still be ideal after lowering given the geometry and spring rate changes not to mention the roll bars. Not to say lowering can't improve handling performance just as a new tire migh but PTM and MR would no longer contain the ideal calibration for the car. Just my $0.02. I've been saying this for a while now and I've seen no evidence as of yet to lead me to believe otherwise. Again, it maybe doesn't matter as the car is completely changed anyway.

We will never know the full potential of the MR dampers with modified suspension until the aftermarket has the ability to calibrate the system. Maybe the dampers are helping, hurting, or are a wash at any given state of the car but they are no longer ideal. So perhaps to unlock the full track potential of the ZL1 with modified suspension you would remove the system. This comes with additional trade offs. Just some things to consider. I'm not saying this is definately true but it is an unknown.

We have been working with various GM MRC system in AU and here in the States since it first appeared on the Holden HSV series about ten years ago. Even the earliest system had the capability to adjust for load. Weight of the driver and an 1/8 of a tank of fuel or four passengers, trunk full of luggage and a full tank of fuel (i.e. LOWERED vehicle). There are parameters that should not be exceeded to work with the MRC system. Stay within those parameters and let the MRC magic happen. Sway bars will have no negative effect on the MRC system. The data the system collects include pitch and yaw. When body lean is reduced, the data reflects that accurately to the MRC system. Better tires for the ZL1 are probably not street legal! While some ZL1 owners may be disappointed with the tread life, it is hard to imagine anyone being disappointed with the sticktion. On the other hand, a square wheel and tire setup with matching 305s up front |

I drove this cross country with three inches of clearance. The hills and mountains in Pennsylvania, the pot holes in Jersey, New York, Chicago and Detroit and more than one race track. I had only one problem with a suicidal raccoon and he would have cooked the the ZL1 front spoiler and lower grille too. The MRC will not take to radical modifications. We don't plan to be radical. Just call us Conservative Activists |

Thanks for that information, Pete. My interest is renewed to it's previous level
Are you guys going to run 19s, too?...

I am intrigued with the idea of running the OEM GY 305s all around. In a perfect world we'll get a ZL1 setup Pedders style and run a bone stock ZL1 side by side to get our head to head data and of course publish it right here on C5.

I have seen some numbers... But I try to avoid getting into the ZL1 stuff. I will be more than content with my SS once it has everything Pedders...however, I love your write-ups. I always learn something new...
