Hi mate
H+R do lowering springs for the frs which everyone uses and are apparently good.
I have a suspiscion that my own frs may be lowered but i bought the car as is and it wasnt mentioned. Either way my car isnt silly low, i just sometimes think it sits lower than others, but only just!
www.rsownersclub.co.uk have a great forum and the mk1 frs section is EXTREMELY helpful. Have a word over there mate
