I think the original poster of this thread now runs a front stiff setup...

Here's a description of RTR cars from Smurf BNMS on Honda-Tech...
The RSX's run 800# front, 3000# rear, what looks like a 25mm front sway bar, and a 42mm rear, both I believe are hollow. The arms and rates of the bars are unknown. Also, the moton canister pressures are 280psi for the rear. The person I talked with said that they needed a tremendously stiff rear to get the car to rotate well, but didn't offer any sugesstions as to why, but stated that the integra's a used setup that was less extreme. On the other hand, the TSX's run 700 to 800, both front and rear, and depending on the driver, uses any where from a 1 inch to a fence post as a sway bar out back.
