You are the 1st person I have read about loosing time on your 60 ft from the bar. I would bet that something was in a bind. are you saying that you unbolted the bar and ran a wheels up with no bar at all? that I would like to see! I know of no one before you, that didnt get a performance gain from using this bar. I believe Paul Ferry was cutting 1.3s 60 ft times with an ATR bar and his control arms!

My best 60 ft time was a 1.401 @ 10.71/125MPH.
For a comparison, most people running mid/upper 10's are around 1.46-1.54 60ft's.
I had the stock swaybar on there at the time. I tried it without a bar, and it hurt performance. For anyone who has seen my car, you can tell that I needed an anti-roll setup. The ATR bar might have helped, but it wouldn't have been the best way to do it. I wish I had thought up our new swaybar idea back then! Our control arms contributed to my great 60 ft (off the foot brake). They let the suspension travel smooth & easily with no bind. This lets the weight transfer quick & then you can launch as hard as you want to
Claude, my guess why you lost 60 ft time (higher #) is that the ATR bar was too wide for your car. That would push the control arms apart & put a lot of side pressure on the poly bushings. Maybe "binding up" is not the correct term here, it is more like causing resistance. This resistance keeps the suspension from moving fast like it need to, and then the weight never has a chance to transfer, and most likely results in wheel spin. Any chance you remember having to really pound the bar in place???
That is one reason we went to this new swaybar design. NO possible chance of binding or causing resistance on any car with any control arms. Another issue to consider is that with a larger stock style swaybar like the ATR piece, the lower control arms are doing all the work trying to keep the body level at launch. This added strain will rip out the forward frame mount for the lower control arms easier. We do make a reinforcing brace that welds on the stock mounting brackets to keep them from being ripped out, but that is still a lot of stress going thru there. That is also a lot of stress transmitted thru the poly bushings in the ends of the CA's, which could cause some binding.
We just found a better way to get the same results
