I have a good suspension setup already but I would like height adjustability on the front rather than have to buy a whole new suspension kit.

Has anyone used these http://www.rallydesign.co.uk/product...70j7qaqtq8fam1 and know if they are any good.

Also would I be able to use my eccentric top mounts with them? I know that if I ordered a new coilover kit for my car I could specify that I required them to fit the mounts.

 

They work ok, don't know about the eccentric top mounts but these are used with std cups.

not the best way to make height adjustable, i've seen them on cars, they do compromise handling somewhat.

 

Nothing wrong with the design inself. Don't know if it's legal in UK, not in Finland at least. The problem commonly is that too heavy spring is selected and combined with old soft absorbers.
If you do the math of buying two front Koni yellows + the kit + springs. The price is not far from just buying Gaz front coil-overs directly.
