I wanted to know which one to buy and where? Does it make a big difference. I was thinking of getting new struts too and continue to use the stock springs on my 97 GLE along with a front strut bar. I'm thinking that this will give me good handling/cornering without getting a stiff and harsh ride. Thanks
If you want a stock-like soft ride, that's a good idea.
Sway bars have very little effect on ride quality. I'd grab the Stealin' because it's adjustable, but the Cattman or Progress bar is cheaper and fine for 99% of everything else.
