Sirion suspension upgrades



Literally just today I bought myself a 2002 Sirion and couldn't be happier (first car finally)

I'm wondering how people on this forum are getting parts from overseas or what parts are good to get hold of here in the UK. I'm a pretty heavy guy (110kg 6"3' haha) and the rear springs felt very soft so I'd like to make them a bit stiffer and would also like to get my hands on the front strut brace.

Any help is hugely appreciated.
