How do you get a Suspension to hook, when the track surface is marginal at best

So here is my next question.
Been looking at Drag Slick. when you get above 26" slicks, there is more options
Is a stiff sidewall for heaver race cars? or is it for higher HP cars or........... maybe stick shift cars??????
What is the difference between M5 and L8 compound
They say a stiff sidewall tire will react quicker but i'm still running the regular wrinkle wall with tubes just don't have the coin to try a set of stiffwalls and not have them work.Without looking at the chart m5 and l8 are the compound of the slick one will be softer,mine are the m5 and are holding up well.
The 8 3/4 i would recommend making sure the housing is straight now and get it braced well on the back they will bend.
