yes already tried them thanks Dave. They are very good and helpful. Item 6 is available from them/ Honda UK but that is all. you can get the same parts in a top mount kit, from various aftermarket manufacturers
In the US you can get full strut assemblies e.g. from KYB (these are also the brand of shocks I have bought) which would make life easy, no spring compressors required, but not available over here it seems. Pity.
So looks like I'll be disassembling the strut as planned using a compressor, hope the set I have got is up to the job. ? not looking forward to that part.
would be interested to know what other people have used parts and tool wise.
coilovers of course another option but dont want to go down the adjustable ride/height route, wanted to keep it stock. and would be more expensive. looks like H&R for example do a nice set but v pricey !
