Just realised you have a "T". Are those an set for the "T" which has different forks?
Springs are springs. Sure they will help raise the nose and reduce sag - but will not address the (imo) borderline useless Hydraulics.
Also - After many years of Sports bikes - I really do not like progressive-rate (variable wound) steel springs. Prefer Fixed Rate or Fully Variable Oleo-Pneumatic.
I fully recommend you chat with @Joesmoe - he fitted Different springs and Cartridge Emulators - this is ONLY AN OPTION on the "T". For the life of me I cannot remember the marque.
