Advise on lowering my Saxo please
 

Hi,

I'm new to this forum. I bought a Saxo 1.1L a month ago.
Yesterday I mount 15" alloys with 195/45R15. Looks nice and the handling is much better.
Now I would like to lower the car. I think 20mm or 30mm will be ok.
With spring do I need to buy ? and where ? (online)
I live in Mauritius, so the website need to ship to Mauritius.

Thanking you in advance for your help.

Regards,

Gregory
