Cant help with the drag racing aspect of it. I just went through this research and was having trouble finding feedback here and on the Corral about those particular dampers.
Here is what I did find: KYBs can be found for 150-ish (for 4). And 4 Tokico HP's can be had for 230-260 for 4 new ones.
The KYB's are about the best bang for the buck per many people but a lot of folks with lowered cars think they are a bit harsh. Others argue that the extra money for HPs makes them a better deal in the long run. I did not look at more expensive stuff since I am poor.
If you have a lowered ride, I would consider fox dampers to get the strut into the sweet spot sooner, since you have diminished travel.
my lame two cents. good luck.
