I seem to have a slightly droopy rear-end on my 1500 Spitfire. I checked the measurement to top of hard top and its an inch down. This results in the exhaust scraping the odd speed bump. My question is simple. Rimmers sell one for around £50, whereas a company in the midlands offer a British-made spring for a much heftier £110 or so. Rimmers used to do a higher spec item but no longer offer it. Which one to go for? I don't like inferior parts, and, of course the Rimmer option may be also be British-made (and by implication, just as good).
Help please!
