If you can fit it in the budget the Hotchkis TVS is probably the best bang for the buck. If not and you just want to do a few things here and there give the guys at Speed Tech a call. They are also in Canada, that may help with shipping and or import taxes/fees. I am not sure how that works.
There are many ways to improve what is already there, Blake or Roger can take good care of you.
Let us know what you end up doing, and include pictures.
