Replacing stock Z51 shocks. Any advice?

Who here has upgraded to another shock from the Z51's.

I don't really need coilovers, I don't race the car.

What choices would you guys consider if changing your shocks, especially if you're changing them on a Z51 Vette?

And if adjustable shocks, how difficult is it to change the setting?

I'd take a look at Pfadt's sport shocks. They seem to have really good feedback on their product line.

I've heard good things about them, too.

Does anyone know how hard it is to adjust the settings, do you have to jack up the car/suspension?

Pfadts were not offered in '05. I went with Konis.
- The ride difference was like day and night.
.....Softer cruising and Firmer when driving agressive.
- Wheel hop went away.
- Bump steer is all but gone.



Notice the residue from my leaking OEM right rear shock. It was pounded into submission and was beginning to fail.

I pulled my Z-51 shocks with about 52,000 miles on them. During that time I did just about everything you can possibly do to a car to them; I drove them across the entire country, coast-to-coast, twice. I drag raced, autocrossed, road raced, I jumped the car, I slid the car, I nailed two potholes violent enough to bend wheels and destroy tires.

They came out in perfect condition; no leaks, no noises, proper rebound, full pressure.

The car was pulling 1.24"Gs" lateral acceleration with them on, along with Road Racing tires, a more agressive alignment, and a C6 Z06 rear Swaybar.

So you really don't need to spend money to "upgrade" anything.

But anyways. I swapped mine out for Bilstein Sports. The Bilsteins feel very similar to the Z-51 shocks; I can't really tell the difference. But they did eliminate the tendency the car had to wheelhop when the tires were wet... So if you have wheelhop issues, that'd be one instance where you may want to consider those shocks...

I just replaced my Z51 shocks with Koni FSD's. The FSD's took the harshness out of the Z51 suspension, yet the car still corners flat. The rear tendency to step out on a bumpy corner is gone. The cars stays planted now. The Z51 shocks have a lot of gas pressure to them. The konis do not, so the car actually dropped about 3/4".

Yea, we are a little rare on car forums. I havent updated shocks yet or changed my suspension, but I thought I'd chime in for a little help.
