There is a reason for this. The redesigned shock geometry of the .3 cars differs greatly from every other offering on the market. With the new design, the front and rear geometries are a lot closer than they were on the .2 cars. To balance the new suspension, a higher rear shock fluid is required in order to get the correct balanced feel from the cars. It is a little strange if you've come from other cars, but the reasoning is correct.
Yes, it can make the car loose. We've been running Joe's setup in order to add rear grip (as well as grip all around) to the buggies and it's made a huge difference. The farthest I would go with shock fluids to get more rear grip is to have both Front and Rear the same cst, i.e. 450/450. Using more of a "traditional" fluid setup gives more rear grip at the expense of poor jumping, landing, and stability.
