XRAY 303363 Left Rear Upright Composite - 1 Degree Outboard Toe-In  [XR-303363]

Stiff Composite Upright for Sharper Rear Response

The XRAY 303363 Composite Left Rear Upright is engineered to tighten rear-end behaviour on touring cars. Its built-in 1 degree outboard toe-in helps the car hold a consistent line in corners, and the hard composite material is aimed at foam-tire competition while remaining compatible with rubber tyres.

Lightweight Bearing Setup

Designed for 5x10 ball bearings, this upright helps cut unsprung weight to improve turn-in and responsiveness. Dual roll centre positions give you the freedom to alter rear geometry for a more planted or more agile feel depending on the track.

Installation and Matching Parts

To achieve balanced handling, pair the XRAY 303363 with the corresponding right-side upright, model 303353. Many racers use this matched set when dialing in rear toe and roll centre settings.
