SAMCO do a lot of the Race Car kit here, protective clothing, equipment etc.
There is also Demon Tweeks and Earls Motorsport.
They do the coloured silicone hoses but also a 'classis black' range.
Have a look at your local 'Boy Racer' store or ask anyone who drives a 1.1 litre car with 4" exhaust and 20" alloy wheels on it!
