First of all, welcome to the board my fellow SR5 owner
You should come out to our meetings.. My SR5 used to be White with black bumpers and blue interior when I first bought it back in 98.
I can help you out big time on any questions or anything regarding the SR5's I have gone through it all..
For your suspension question, struts are pretty expensive. The springs are about $400 1.6" drop and those are the APEX (The ones I have) For your struts you should probably pay about a bill and change for each strut (KYB's) other than that I don't really know of any other struts for our cars.
You should definetly consider coming out since you're in TO, the meets are great. And I'm sure everyone would be happy to have another AE92 coupe along.
