Guides
Short notes on clutches, valves and brakes for the Skyline GT-R and R35. Each guide points at the aftermarket parts in the catalogue that match its subject.
Our guides share general advice gathered from manufacturers, published sources and our own experience with GT-R parts. We check facts against more than one source, but makers change specs and every car is different. Use them as a starting point, confirm fitment with us or your specialist before buying, and have parts fitted by a qualified mechanic.
