Correct rubbing won’t occur if you are careful.
Sag in the rear is common and can be cured cheapest with T32 springs on the back but won’t get you under 2m presuming you have a taller pop top.
Lowering springs alone may help but not guaranteed to level out, heavy duty versions are available though.
Lowering springs with adjusters are available but seem a lot of money for what they are.
Sports shocks and lowering springs may work and give more comfort than coil overs.
Most would go coil overs for adjustability, which ones.........do a search if you have a day or two free it’s very subjective. You can spend £300 or £2000 the choice is yours.
This is B14s and 20s for reference, t30 but had a sag in the rear due to conversion.
