Default z06 shocks

I may be wrong but I think I read in here somewhere that z06 shocks would stop the bottoming out on a lowered car. Seems they are shorter them non z06. This is on a 99 ragtop lowered on stock bolts. Is this true or am I hearing voices again.

I don't know for sure, but I have put Z06 shocks on a reg. coupe.
The only differance I noticed was the Z06's were larger in diameter.

Definitely hearing voices. I'm not sure if you mean it would stop the car from bottoming, which is unlikely, or the shock. If the latter, I know LG's coilovers aren't easy to bottom out. http://www.lgmotorsports.com/catalog...dd276fd77a9994

Coilovers $2395.00 z06 $200 wish the voices were right. Talking about the shocks bottoming out on hard dips.

Any C5 shock is the final limit of upward wheel travel, the spring needs to be stiff enough to keep the shock out of this operating area. When the car is lowered the spring pressure needs to be increased to compensate therefore if a car is lowered without increasing the spring pressure then stresses are transferred to the shocks when they bottom out and the ride quality suffers. If the roads aren't good then the shocks and or the shock rubber mounts fail. One reason Pfadt coilovers work well is because the spring pressures are 50% stiffer than Z06 springs so a good ride quality is maintained even though the car is lowered. Instead of changing shocks I would change to stiffer springs first so the car doesn't bottom out and the shocks last longer. Check the aftermarket springs available and compare spring rates to what you have now.

Your right it was the springs not the shocks. Shocks are for up, springs are for down. I told you the voices were talking.

The problem you are encountering is because you don't have enough suspension travel because you lowered the car too much for the suspension you have. If you want to keep your car lowered where it is you should switch over to coilovers. I believe GM recommends that you don't lower the car more than 1 inch with the stock suspension.

Springs have two functions: (1) to keep the tire in contact with the ground, and (2) isolate the occupants from the bumps and other imperfections in the road.

Dampeners (shocks) dampen or control the springs so that you don't go bouncing down the street every time you hit some imperfection in the road.

Basically, what happens is when you hit some imperfection in the road, it acts on the suspension through the spring which either compresses or expands depending on whether you hit a bump or a dip. When the spring tries to return to its position the shock (dampener) controls how quickly and how fast the spring does that.

There are tables of spring rates and aftermarket suppliers of both coil overs and composite springs in the search area and in Google, type in c5 spring rates.
