does adding AGX's and H & R's ...give better traction resulting in better 1/4's??

 

Not realy, alot of sports car are low to block the wind, but in the maximas case dropping your car may improve your 1/4 mile on a windy day compare to it being stock and doing the same 1/4 mile on that same windy day. But thats only on a windy day any other day I think it would be the same time drop or stock.

 

yes it will, stiffer springs and struts will improve launches because the stiffer suspension will keep more weight over the front wheels improving traction on the launch

 

well with the wind and all, your car breaks the air at whatever mph which is kinda like wind pushing against you, called drag, ever stuck your hand out the window? well the car being lower cuts the wind a little better

 

No, it will not help very much if any.

I have dragged with:
Intrax w/ OEM struts
InTrax w/ Tokicos
GC's w/ Tokicos (With a 2.75" up front & 2" in rear)
AGX w/ Sprints (Sprints are lower in the front)

I have over 20 slips with each setup & not once did i drop my time. I dont think our cars have enough power for us to really start seeing the advantages of stiffer suspension. I thought it would help my launches & grip since i ran 100 shot but i was wrong.
