Hi, I'm considering lowering the suspension on my 2002 model honda civic hatchback. It has 16 inch alloys with low profile tyres on. I phoned Demon Tweeks at Wrexham and they said they wouldn't lower it any more than 40mm without having to change the shock absorbers. I don't want to have it lowered and then find myself getting stranded on speed bumps etc. How low do you think is okay and what make of coil springs would you go for. Please help?
