I modified a 1988 Chevy Camaro 35mm sway bar to fit the Coupe.
Surprizingly easy modification and it cost me $35 for the used bar.
I was also surprised to find that there was no increase in understeer.
I do not have a rear sway bar and on wet roads the rear end will 
start to slide undr lift throtle conditions (than you control the 
slide with the throtle).  Under dry conditions the car remains fairly 
stable and rear end can be kicked out with trail braking.
I found no need for the rear sway bar. 
BTW I use stock springs (different than 4000) and Boge Pro Gas all around.
I find the suspension stiff enough for the Toronto roads.
