BMW X5 E70 3.5 4WD 10-13 Ultra Racing 4-Point Front Upper Strutbar 639-Point – URTW-TW4-2639P

UltraRacing is a Malaysian manufacturer of chassis stiffening and bracing components founded and headquartered in Malaysia. The brand specialises in bolt-on structural reinforcement parts designed to reduce chassis flex, improving handling precision and tyre contact consistency for road and track use.

Their product range covers front and rear strut bars, front lower braces, rear lower braces, side lower braces, and anti-roll bars. UltraRacing bars are manufactured from steel and aluminium, with adjustable designs available for fine-tuning chassis balance. Fitment coverage is broad across European and Japanese vehicles, with a particularly strong range for Volkswagen Group, BMW, Honda, and Toyota platforms.

On track, reduced chassis flex translates to more consistent suspension geometry under lateral loads, which improves corner entry stability and overall handling predictability. UltraRacing products are a popular and cost-effective first modification for track day drivers looking to improve chassis rigidity before investing in more expensive suspension upgrades.
