I'm in the same situation, rear shocks have 115k and I want to lower a little and not change the ride quality too much.
A set of Konis/Bilsteins plus springs are around the same price as coilovers. ST (made by KW), Tanabe (KYB dampers), or a little more would get H&R (Bilstein dampers). Then there are the Tein SAZ which seem like a bargain at around 2/3 of the price.
A lot of people hate on Tein, and a lot of people are happy with their stuff. A lot of people hate on any coils under $2000 or whatever number they pick out of the air that day. Maybe that would apply if I was looking for track coils, but it seems like a lot of companies are making cheaper coils without all the bells and whistles for just daily street use.
I'm currently leaning towards the Tein SAZ or maybe ST.
ST probably wouldn't be a good idea since you are in Toronto, they supposedly don't have great corrosion resistance.
