Looking to upgrade my sway bars.I would love to hear some pros and cons of each option from the pros?

 

There are a lot of threads on this subject. I have copied one of my responses to a previous thread below.

The sway bars are a great upgrade.

Shocks would be good too, but how much improvement depends on the condition of your shocks now.

I put C6 Z06 bars and metal end links on one '99 Z51 and C6 Z51 bars and metal end links on another '99 Z51. Both had low mileage and I did not replace the shocks since they were still fine. (Both of these C6 sets use the same front bar and the only difference is the rear bar.)

The results were great. The car corners much flatter and there is very little difference in ride quality (harshness) between the C6 bars and the stock '99's.

I have read that the C6 Z06 bars will produce oversteer with the stock size C5 tires (under 325), and the C6 Z51 bars are better for the stock tire sizes. Both of mine were on the stock size or 285 rear's and they felt the same. I have pushed the C6 Z51 bars and I did not find an oversteer. I have not pushed the C6 Z06 bars as much, but I so far they feel the same to me as the C6 Z51 bars. Maybe if I push it harder I would notice a difference?

The sizes and some part numbers are shown below.

Good luck.

 

suspension is an overall, bars, springs, shocks. if you replace one there should be some measurable goal. more bar out back increases oversteer, more bar up front increases understeer. if you want one end or the other to change act accordingly

personally, if i had a base car, i'd find a wrecked z06 and rob the bars, shocks and springs. c5z setup is very very good for street tires

 

just installed used c5 zo6 sways and shocks on my base and so far I am very happy with the ride and cornering. bought them off this forum, got a good deal

 

I think overall that might be the best way to go.
