That was one of the reasons we made our Torsional plates that attach to the bottom of the chassis rails, to box in the frame rails and stiffen the chassis.

So My point is that replacing the bracket that broke needs better thought process then just replacing the bracket.....

Sorry for the long post.....just another opinion....plus your chassis has a bit of age on it.....

Morris you are correct on all counts. We will upgrade the gauge and design of the brackets. I would like your system better but need to consider originality too. I think we can make it work, the RH bracket held and the left cracked before and we wire welded it (a mistake). I think this will work for a year or so till 3170 retires. Olddog when the car spins the tires it blows them off so completely that the available friction goes down so it does not load the chassis nearly as much as pass after pass with maximum adhesion. Think of it as a burn out where the tires slip but the car barely moves. Same thing happens on a reduced scale so that loads are greatly reduced.

I have a 2018 Ford GT coming in early October so CSX3170 will get more rest time. It started on the production line in Canada this week. I am sure it won't be as wild a ride and won't sound as good but it has killer aerodynamics so should be interesting to track. I don't think you can adjust much but maybe we can add some improvements starting with tires.

I have tried various traction control systems over the years and even built a few. One actually turned lights on in my helmet so I could see that I was losing traction and react. Others were too hard on equipment this system allows you to tune for exactly what you need. Thanks to all the drag racers for developing the system to such a high level.
