Pro Tip: Titanium hardware is not just for show. Every ounce matters in a race build, and the transmission-to-engine bolts are some of the heaviest individual pieces of hardware on the engine. Replacing them with titanium saves real, measurable weight — and the hollow-dome design takes the weight savings even further while looking clean in the process.
