As a Factory-appointed genuine Heritage Parts Dealer, the R.S. Williams Parts Department holds a comprehensive stock of genuine Aston Martin parts for cars built from 1959 to the present day. We also produce many parts which are unobtainable elsewhere for fast dispatch worldwide. 

Upgrading your classic Aston Martin is something that’s been synonymous with RS Williams Ltd since our conception 1968. If you require more responsive feedback from your car’s handling or more bite from your brakes, our brake and handling packages will be ideal for you. For those looking for more power, we have some astonishing engine conversions available to raise your car to modern performance standards. Contact us for details on our DB4/5/6 4.2 and 4.7 litre upgrades and our V8 5.7 and 7 litre upgrades.

A big part of what we do besides all the refinements and upgrades is full vehicle restoration. Every car can be recovered back to better-than-new condition given enough care and skill. We have specialised in this since our inception and have brought a great many of the world’s finest and best-known classic Aston Martins back to life, winning races or trophies, sometimes both. We work closely with our clients to understand their requirements, then develop a specification combining their ideas with our experience. Cars are photographed before work commences and carefully documented throughout, ensuring seamless history which benefits the car’s history file and subsequent re-birth.

Besides rejuvenating a car’s appearance and function throughout, an RSW restoration is an accolade which enhances a car’s value. We understand classic Aston Martins down to the very last nut and bolt ensuring rebuild to a truly authentic original specification. Preservation is in an extremely sympathetic manner due to meticulously chosen finishes and materials and a thorough understanding of how the cars were assembled first time round.
