Regardless if you use the stock keys or + keys to gain the extra 2" or so, your ride will stiffen the same amount.

That kit is also very expensive, + keys are usually around $50 a pair. You don't really need the shock brackets they supply, but if you want to maintain the same shock extended/collapsed lengths as stock, you could replace the shocks for less than $100, which would be a better way of doing it.

Try cranking up your torsion bars, approx 1 turn = 0.2", and I'm guessing you'll get the desired result. Once you are happy with it, drive 50 miles or so and then get an alignment.
