I recently bought/traded for a set of qa1 f series 12 ways all around, new in back, used up front. I am debating getting a drag spring for up front and using the stock spring in back. However, I am bewildered as to what to do next. What would be next in my quest for traction? I am using 255/55/16 ET Street Radials on salad shooters for my racing tire. Any suggestions?

 

Tubular LCA's with LCA relocation brackets.

What else is done to the car? Engine mods...? Suspension mods.....?

 

It is a h/c auto car putting around 350 to the tire.

 

Injuneer has it right. A set of lower control arms and relocation brackets would be the first place to start for straight line traction.
