I bought my vette(99 coupe) used,it has active handling and the "'performance handling package" a 350$ option.I know what the active handling is all about but is the "php": option the z51 option I often hear about?

To find out if you have the Z51 package look at the RPO sticker on the inside of your glove box. If you see Z51 on the sticker then you have the Z51 package.

Thanks ed,does anyone know what the" performance handling package" is? Furthermore what is involved w/ the z51 option?

wlean99

Corvette ed,yea,just lifted the cover and it has the z51 on the rpo sticker on glove box door.So what is z51 about?

Z51 gives you the performance rear end (3.15), thicker sway bars, better shocks and a power steering cooler.

coia96vette..THANKS! a bunch, really i mean it.Have been seeing this option mentioned for some time now and finally know whats all actually involved

I thought it was 3.42s. The best part about the z51 is that you can upgrade the shocks without having to bypass any sort of programming.

The 3.42 gears came with the 6 speed manual. The autos came with 2.73 standard.

The springs are also a performance version, are they not?

wlean99

Thanks for all replys,guys, funny someone at work mentioned the springs…yes..no?

coia96vette

Never heard about the springs being different. I have the Z51 on my 04 and believe the springs are the same with the thicker sway bars and better shocks.

coia96vette

I just rechecked the specs for the Z51 and it does include stiffer springs.

wlean99

little confused,my 6 speed z51 has 3.15 gears or 3.42 ? springs still up in the air

wlean99

o.k stiffer springs ,thanks

coia96vette

6 speed will have 3.42 gears either way.

coia96vette,thanks for clarification
