Mate, Lots of different strut/brake combinations available and the guys here seem to have a wealth of knowledge but you probably need to give a bit of info an what is it you are trying to achieve ?

If you currently have a front drum brake set up and just want the basic disc brake setup then 120y or Sunny struts are an easy change.
If you want bigger brakes then 200b or Stanza struts may be the go and this would allow the ability to upgrade to bigger disks and calipers in the future.
There are plenty of other bigger, better and more expensive options, but how much have you got to spend ?

Yes TRX Rims will go on Stanza struts with no problems.
