I would be very cautious about buying a strut brace because of clearance issues with the supercharger.
I have a Harrop HTV2300 on mine and I had to remove my Whiteline brace because I did not want it hitting.
I know your HTV1900 sits a bit lower but I think it is something to be aware of.
I replaced all the bushes on mine with SuperPro a little while ago & just run heavy duty struts & shocks with stock springs
& I have an Eaton Truetrack in the rear to keep it a little bit straighter.
It's certainly no roundy roundy track car but it is a huge improvement on old worn out stuff.
