I have been asked many times if these braces are really necessary and do they work. I will relate my own personal experience and you can judge for yourself. Before installing any braces I found three banked curves and pushed them to the limit to see how fast I could take them. I installed the front brace and to my surprise, the car stayed straight and level like a slot car and I was able to take the curves 15 to 18 MPH more than with out the brace. I am talking tire squeel and slippage. On one curve I actually felt the rear end "move and twist" slightly so it was then I installed the rear brace. No more moving and twisting it worked. To tell the truth, I never pushed the curves any further because I did not know if I would just slide or roll when losing it all together. If you like taking curves they are great ! I Iost many ricers on curves and seeing the look on their face was priceless. As far as straight up drag racing I don't really see much benefit if any at all.
