I'm very happy with them - the car feels super tight. I think i'll need to swap in some 90/10s up front for drag racing, though.

If you don't intend to spend much more for
coilover suspension, go for KONI's.
They are great improvement over stock shocks.
That is KONI Sport Adjustables I'm talking about.

A great shock for the money. Just put them in, and what a difference over factory replacements! Set them to the mid-level ajustment, and it's perfect for street use. Edelbrocks are twice the money, and I can't see those being worth that much.

The Edelbrock's I bought were half the price of the KONI's I replaced them with, and were about 1/10 the shock (for what I wanted them for).
I really like the KONI Sports. As I've said on threads like this before, they aren't as trick looking as their competitors...they look like they should be on a Caterpillar road grader...but they work and KONI stands behind them.

PS I have the fronts set two quarter turns from full soft and the rears on full soft and like how the car handles. It might be a good place for you to start if you put them on your C4.

I know you well enough to realize that you are just giving me jabs, CompYell.
Yes, two quarter turns equals one half turn.

My old motorcycle Koni's (1970's) adjusted their damping by turning the damper rod in quarter-turn increments. While my C4's KONI's instructions don't mention this (I guess they are infinitely adjustable??), it's an old habit for me to use "quarter-turn" increments.
I did some testing of 'turns vs. damping' on the Koni's before I installed them, using quarter-turn increments,and charted the results, so I stick with the 1/4 turns so I know where I am on the damping curve.

Compare to Bilstein's?? The KONI's are adjustable, the Bilsteins are not. The Bilsteins are cheaper and probably a better value if you don't need that adjustability. Nothing wrong with Bilstein's...probably the best non-adjustable shock you can put on your C4.

***********
I am looking to replace my OEM shocks on my 99c5(z51 susp.) and am trying to decide between the HDs and the SPORTs from Bilstein. The car does not get much track time and is more of a cruiser/daily driver on sunny days Wondering if the Sports will be too harsh vs. the HDs...? I'd appreciate any guidance you can give me.
thanks - Damon

I just went to the Bilstein site, to see what the difference is between the HD and the Sports. I couldn't find the information.

Gut feeling is that the Sports would be the tighter-valved unit. If that is true, then the HD will provide a softer ride.
Either way, the difference will not be all that great.

Not having any experience with the z51 Bilstein's, I couldn't say. Here's a thought, though; if ride quality is your main criteria, you probably don't need the adjustability or the cost of the Koni.

If shopping for the Koni Sports for a C4, take a look at
Lingenfelter. Their price is 138.95/ea ($556/set) for
the 8241-1097 (FR) and 8241-1098 (RR). Their prices on Bilstein aren't
the lowest but they have the best deal on Koni's that I've found.

Shox.com has them for $572

TireRack has them for $572

eShocks weighs in at $599.76
Koni's are at the bottom of the page.

FWIW - I recently purchased Bilstein Sports (from shox.com) after
considering the Koni's.

Koni's are great, I still have a set of the pre-gas era adjustables on
another car. But it looks like the current Koni's are still awkward to
adjust and I'm past the point where I am willing to pull things apart
just to change damping.

There has been enough praise for the Z51 Bilstein's that I don't
think I'll be too far off the mark. If anything, for my purposes maybe
I should have ponied up for the ones with the Auto-X valving mod.
I can always send them in for this in the future.

Just installed them last week. They are very good and what you may expect from oem equipement on a Vette.

If you don't want to go the even more efficient coilover route, this is the set up to choose.

I also went with the Konis after trying QA1s. While the rear are not easy to adjust the car rides and handles better than it ever did. The factory Bilsteins were horrible even with only 22k miles and no they were not blown.

The factory Bilsteins in the nonZ51 cars (at least on the 95 models) are valved so that when the targa top is removed, body shake and quivering is minimized (but not by much). This means they allow the car to wallow around and offer lousy damping over sharp bumps. The adjustable Konis are far superior to the factory Bilsteins and only slightly worsen the body shake and quivering with the top off. You will not be disappointed.

In defense of the Bilsteins, I installed aftermarket Bilsteins on my 79 TransAm WS6 and they were excellent. I was really surprised with the Bilsteins on the Vette. But GM probably set the shock valving for these shocks. GM did not set the shock valving right in 95 and apparently still has problems setting it right in 2006.

I have not heard that the shocks are valved for top off driving.

Most interesting.

Have the Koni Sports on mine now, the adjustable yellow ones. Had QA1s before. Liked the QA1s better for an everyday driving type of street shock, but like the Konis better for the autoxing and hard driving I do. They also seem to work better with the really stiff Z51 springs and bars I added. I like them, never adjust the backs just the fronts for competition. Both the Konis and the QA1s were way better than my stock Bilsteins, but the stockers where worn out so that may not be a good comparison.
