RS Uprights for Porsche 964 & 993 Elephant Racing Suspension Products

Описание к видео RS Uprights for Porsche 964 & 993 Elephant Racing Suspension Products

Special front uprights (wheel carriers) were equipped on the 993 RS and cup cars, correctly called RS uprights but sometimes called GT2 uprights or EVO uprights. The reason for RS uprights is to correct undesired geometry changes caused by running a lower ride height. This is the right way to lower your Porsche 993 or 964.

RS upright advantages include improved suspension travel, superior camber gain, and reduced bump steer. The result is superior performance and ride quality. RS uprights are an awesome upgrade for any lowered 993 or 964 including C2, C4, and Turbo.

Elephant Racing designed RS uprights faithfully reproduce the factory RS geometry. They are made of aircraft grade 7075 aluminum billet for superior strength. They are a direct replacement for the factory 993 RS uprights.

They accept standard 993 front wheel bearings and cover plates. GT2 type tie rods are required. There are three basic differences between RS uprights and standard uprights:

First, the wheel bearing has been moved up about 15mm relative to the ball joint Second, The steering knuckle is relocated and has inverted mounting of the tie rod, and Finally, RS uprights are aluminum as are standard 993 uprights. 964 standard uprights are steel.

Lowering a 993 with stock uprights causes several undesired geometry changes, all of which are corrected by the RS uprights.

RS uprights improve camber gain. The lower control arm angles up at the ball joint end, putting the suspension in a poor point on the camber curve. RS uprights angle the lower control arm back down, thus enhancing camber gain and ride quality.

RS uprights improve suspension travel. Lowering the car compresses the front strut and reduces available suspension travel. The result is premature bottoming out, poor handling and ride quality caused by contact with the bump stop – which creates an abrupt and unsettling rise in spring rate at that corner that unsettles the car. RS uprights put back suspension travel.

RS uprights reduce bump steer. Lowering the car moves the stock tie rod into an unfavorable position on the bump steer curve, make the car a handful to drive over uneven surfaces and requiring frequent adjustments at the steering wheel to maintain a steady trajectory. RS uprights relocate the tie rod end placing bump steer in a favorable position on the curve at lowered ride height.

Available for 89’-98’ Porsche 964 and 993.C2, C4, and Turbo Models.
