Stock deCarbon shocks would probably be better than what you have, but they are very expensive. A better choice would be Bilsteins. There are "soft" and "firm" Bilsteins available. The firm are probably a better choice. Having gone from a soft shock(Monroe ST) to a firm one(Monroe SS), the ride is actually better with the firm one.
I ran Monroe SensaTracs for 40k, and they are not floaty under normal driving, but they are not the best thing for performance driving. Probably the closest shock to the deCarbon.
Another option are the Monroe Severe Service shocks, but they do not have a lifetime warranty like the Sensatrac or Bilstein. Since they are new, lifespan is an unknown. I'm guessing they are similar to the "firm" Bilstein in feel, but I've not had a chance to compare.
Not all that much more than deCarbons, would be the HAL QA1 shock, which is a 12 setting adjustable, from almost no shock to almost solid and they are rebuildable.
I'd stay away from Edelbrock and KYBs.
