Which of these react better to modifications and genrally a better tuner car? Is there a reason I see more DSM than All-trac's at the track besides DSM are easier to get and made by 3 companies?Thanks

i have a 96 gsx. thats a 4g63 block stock 210hp awd. the mods are veary inexpensive. you can run into the 12sec 1/4 with $1800.
