Just got my new 4 link dragster out finally,the best thing i can tell you is after 12 years of hard tails and slip joint cars(all were new when i drove them) there is no reason not to have suspension on a dragster.They stop significantly safer/faster=no bouncing and driving them back to the trailer is nice and smooth.They also seem to be more consistent but i only have 3 races on the new car as of now,all of the 60 ft and 330 ft increments are dead on run after run.....finish varies
