Question

Hey Guys,
What do you think about the edelbrock shocks for our cars? How do they compair against bilisten,koni,kyb? I am looking for a great dual purpose shock for a daily driver. What do you think??

...I have the STIFF bilsteins. If I had it to do over again I would CONSIDER the early b-body bilsteins since they are a little, less stiff for a daily driver. But since the rears are such a PAIN to de-install/install, I will keep the tight bilsteins on my car! I would discourage you from anything other than the finest production shocks in the world. Edelbrock makes engine stuff...not suspension stuff!
Here's another tip: When I installed the stock, GM SS springs on the rear of my car, I deleted the lower spring insulator, why: because I was told the car would be, "more responsive". Maybe, but it was 'thumpy' as hell (in my mind) for a daily driver. AFter a week of that crap, I quickly re-installed the lowwer spring insulators, result: Ahhhhhhhhhhhhh...quiet again, but still schtiff as hell due to the bilsteins. Use the stiff Bilsteins for autocross...the soft ones for daily driving. If I had it to do over again, I would install soft bilsteins and HEAVY sway bars...I think that would be the best compromise for RIDE + performance. As it is now, when I get around to installing stiff bars, my ride will get even 'worse'! Remember: sway bars will transfer suspension travel from one wheel to the other wheel on the same axle. So: stiffer bars equate to stiffer ride and stiffer shocks will exacerbate it...something like that. Just my 2cts worth. [img].gif[/img]

Marlon, it's actually the Bilsteins for the newer models that are "less stiff" (1516 & 1517 I think) versions. The ones for the early caprices are the stiff ones (1104 & 0929)... Just an FYI.

Now, my opinion on the stiff bilsteins... I LOVE them [img]7.gif[/img] !!! I kinda wish they were a tad stiffer though. I know I would have been severely disappointed if I had bought the floaty stiff bilsteins... The ride now is controlled and by no means harsh. It's not even close to riding as stiff as a CamAro or Vette. And for now, I have stock SS springs and sway bars front and rear.

Here's my take on the others judging from other people's experiences that I have heard. I have no personal experience with the following... The KYB's work great for about a year, then crap out. Edlebrock's are known to be troublesome, they fail very soon after installation from what I've heard. Not sure about the Koni's. I think Ed (AutocroSSer) used to run the adjustable ones and liked them. For the ultimate adjustable shock, you'll want the HAL's. These are my dream shocks. But too pricey for me.

Just another opinion from just another guy on the forum. Take it FWIW....

If I were going to spend money on shocks(and I really want to, but can't right now), I'd go ahead and buy the HAL shocks the first time. There is a GP going on right now to buy a set for $485. That's only about $100 more than a set of Bilsteins, which may or may not be right for you.

They are adjustable from almost nothing, to almost solid, with 12 steps. They say it only takes 5 minutes to adjust all 4. Externally adjustable, billet aluminum, rebuildable, what more could you want? The right shock for everyone.

Save up some bucks and buy the HALs. Best thing you could do for handling.

At what mileage are you guys finding your stock shocks in need of replacing generally?

I think the common denominator here is that both guys with 9C1's might find the 1104/0929 shocks objectionable as far as ride, especially if they are no longer running the stock size tires. I did note that one is now using SS rear springs, so that should lessen the harshness, as the SS springs are the "softest" on the list of GM replacement springs. I am not sure how much difference there is in the rear spring rate on the 9C1 vs the Fleetwood, but the combination of more weight, (probably) lower spring rate, and control arm bushing differences probably help the Caddy feel less harsh with the same shocks, at least in the back.

I would suggest that the 9C1 guys might give the stock Impala SS shocks a try--something in between the "stiff" and "soft" Bilsteins. Too bad they cost a bit more new, but they are good shocks.

I will say that I've had Edelbrock shocks on my car for the past 2 years, and they have held up so far. It took 2 tries on the rear --they acknowledged having a seal problem early on, but that is all in the past, I am confident.

The other thing I will suggest is to make your decision about shocks with the car adjusted to a condition that was equivalent to what the manufacturer did to make the shock selection/tuning, then figure out where you want to go, or what happened when you made a change that would affect the ride. An example of this is tire pressure, which will affect ride quality considerably--you should adjust the pressure to what is on the label on the door and see if that makes the car feel better or worse. I suspect most of us run more pressure in our tires for daily operation on the basis of "more is better", for better fuel mileage (always an issue, especially with these cars) or some other perceived advantage it may give. The factory selects the tire pressure range with many considerations in mind, and ride quality is right at the top of the list.

The previous owner of my car replaced the stock shocks at 40k. He said they had given up the ghost by then. He put some Monroe Sensatracs on, which are fine most of the time, and inexpensive, but are not really up to spirited driving.

Thanks for the responses, so what I can gather you all would not recomend the edelbrocks, but instead would go with stock SS or the early bilstiens as a good compromise. Thanks again, I should have known another Keep It Simple Stupid moment.
