I would say that yes they are worth it. I have the tapered ones on my car and they really helped the car handle better in the woops section at my local track. I did not notice the difference on the larger jumps but definately on the small stuff. The cost is a little high but you must consider GHEA is not one of the large manufacturers and are not producing large volumes, therefore cost is higher. Even with some automated equipment I would not want to produce and sell these for under $20

Not to get into this whole big bore discussion but you must consider that Associated will be releasing big bores in the next couple months. If you are like me and need all the new s-it as soon as it comes out then switching to these now might not be the smartest investment but that's your call
