I'm planning on using 15" wheels which will raise the car by 1/2" and high profile tyres which will add a bit more but I think I need to find another way of routing these pipes nearer the centre of the car.
Ever wondered what the regulations are related to speed bumps?
Well here it is....
https://www.gov.uk/government/upload...ic-calming.pdf

Page 47 onwards covers speed bumps specifications.....

"the Highways (Road Hump) Regulations 1999 still allow a maximum height of 100mm" but this document goes on to say...." a maximum height of 75 mm is recommended for individual road humps that are not raised junctions "


So my conclusion is that my 85-100mm unladen clearance is not enough so Plan B is currently being designed.......
