The new RPSport
Subframe Support Brace
Plant the Rear End * Reduce Wheel Hop * Stiffen Rear End Flex
We are pleased to bring to you the new RPSport Subframe Support Brace. The hottest new product for the S13 in 2009! The RPSport Subframe Support Brace replaces the factory support bar between the rear subframe and the mounting hat and the chassis of the car. With our years of experience we have developed this brace, out of the highest quality aerospace grade alloy.
The factory bar is a mere 1/8th of an inch thick x 1 inch wide. Made of mild steel, the bar is there to absorb some subframe flex against the rubber mounts. From the factory, these bars are straight when installed in the S13. Quickly over time though, the bars bend and twist. This can be due to many factors, but nearly every S13 that has ever come through RPSports doors has had the factory support bar bent on at least one side.

Comparison between the RPSport Subframe Support Brace and a (bent) factory support bar
Factory Support Bar as stock (bent)
The RPSport Subframe Support Brace is manufactured in the USA, made of 6061 T6 aluminum, cold cut and emblazoned with the RPSport Logo. The RPSport Subframe Support Brace is over twice as thick, and much wider than the factory unit. This added size, strength and bracing force makes for a nearly indestructible piece that carries a lifetime warranty against snapping.
The performance gains from the RPSport Subframe Support Brace are huge. Off the line launching is stiffened giving a sharp feel to the throttle as front to back sway is greatly reduced. Cornering and road feel is increased as the rear end stays firmly planted under acceleration. Under hard cornering and drifting wheel hop is marginalized giving a smooth, predictable and steady feel under drifts and transitions.
Included with Each Set of RPSport Subframe support braces is all the hardware you will need to completely replace old hardware, and fasten your new RPSport Subframe Support Braces to your S13 240sx.
The RPSport Subframe Support Braces ship USPS Priority Mail anywhere in the United States for $5.15. We also ship the RPSport Subframe Support Brace anywhere in the world using USPS priority mail for $13.50.
