The Torque Rods come in different strengths and a spot of color on each rod identifies the deck lid configuration they were designed to support. If the paint is worn, faded or missing, you can also tell by the RPO code what torque rod should have been on the car.
Red = plain
White = Spoiler (RPO code D80)
Blue = Luggage carrier (RPO code V56)
There is also the adjustment holes to 'fine tune' them. The torque rod retaining pin seems to come from the factory in the center of the 3 available holes. The Shop Manual says "To increase tension on torque rod, move the pin rearward one hole." But, be VERY CAREFUL! There's a lot of tension there.
If you do a search of PFF, there are many threads on this topic. Since the PFF search engine isn't that good, I use google and enter the search string: "site:fiero.nl torque rod". I came up with 983 hits.
