How do they need to be set?
Please help

I believe that you are talking about the tweak screws? If that is the case, the last time I ran a t-plate car (early 90s), I would put the car flat on a table, ready to run. Next, lowered one screw until I saw the light gap disappear between the screw and chassis. Repeat for the other screw. There should be a slight gap. Next, turn each screw a little at a time until they actually touched.
The biggest problem was not pre-loading the t-plate, as it induced some horrible reactions, and possibly pre-maturely fatigued the fiberglass.
Back then I used a tweak station to set the cross weight (tweak). Now I see people using the coins on the front wheels. I still think the tweak station is still the best method.
It is still a tuning option. With the Rev.5L we are leaving the tweak springs backed off all the way unless we really need turn-in. I know of good drivers that will leave the screws backed out equally on a t-plate.
