Demon Tweeks are probably the largest dealer of performance car parts and motorsport equipment in the UK.
Demon Tweeks specialise in mail order sales and their yearly product catalogues are the most comprehensive of any company in the industry.
Although the Demon Tweeks part business was built on the back of their mail order catalogues they now have a website which has an even larger range of parts than their paper catalogues.

OUR HISTORY – Demon Tweeks was established and founded in 1971 by Alan Minshaw to service the needs of the Motorsport Competitor. Alan, an accomplished racing driver since 1958 and former motor trade salesman, identified the opportunity to supply everything the racer could need from one source. His principles of offering top products, quality, service and rapid availability are as important to Demon Tweeks today as they were in the beginning.
