Thanks for that guys . Good idea with the Jap stuff . Ive got some good contacts in Japan , who may be able to help out with parts . I have measured the top of the strut now , which will make the research a bit easier . I also noticed that Demon Tweeks have a universal top mount so will investigate that further .
I have got a few weeks to sort it out anyway , as the new springs wont be here for about 3-4 weeks . For reference I used
http://www.coilsprings.co.ukwww.coilsprings.co.uk who are doing 220lb springs with a 15mm lift in ride height for £94 delivered . Must be better than the ones Avo made up for me , which I think have settled too much anyway , making it slightly lower than standard .
