I saw somebody on here once post something like "girls squat, race cars don't", well go to an NHRA national event, sit close to the starting line and watch the faster Super Stock, Comp Eliminator door cars, and the Pro Stock cars. The back ends set down, or squat, when they leave.
4 link cars vs. Stock suspension? Makes adifference?

not talking SE guys. And most of us don't run huge 30" radial slicks on NHRA prepped tracks.

I have never seen a car hook better with "LCA brackets". I could see no point in them, but did try a set like everybody else. And, yes it applies tall or short tires. Some guys will buy anything if they see somebody else using them. Like my dumb *** did. Took mine back off and it worked better again. A lot of this stuff is monkey see, monkey do.

A lot if that has to do with your ride height and lower control arm angle. If you lower your car in the rear, how do you change your LCA angle without brackets?

When I put taller tires on it I had to lower the back end (softer & shorter spring ) to get it back level. Nothing uglier, imho, than the *** end sticking up in the air. Still worked better without them. 1.30 60's on the rear tires well past the 60' clocks, seemed to work OK.

The torque arm is what plants the tires anyway, not the control arms. It ain't like adjusting an actual 4 link.

Well, a car I crew/work on went 1.10 60ft on radials last night at 3290lbs with some long control arm brackets. Seem to be needed in that application.

Bet it wasn't a normally aspirated 350" LT1.
And I doubt they are needed.

I totally disagree with all of this,1.30 on the back tires would equal about a 1.20 if the front end was on the ground, not happening. Been there done that. We have been 1.27 front end down and 1.40 on the back tires at the same et. 9.80s at 135. If your control arm angle is wrong it will drive the rear tires up at the hit instead of planting them down . Basically its a 3 link suspension.

Enough people have seen it do it, over and over. It does go 1.20s when the front end stays down. Class final at the Topeka, the Kansas Nationals this year. Stood straight up & unloaded on the wheelie bars so hard it shifted and guys on the starting line said they could hear the tires squall, 1.29 60'. Plenty of witnesses. Was afraid I lost that one.

Definitely wasn't a naturally aspirated anything and doesn't have wheelie bars. They certainly are needed to get the LCA arm angle at the right degree. This was also on a 275 radial, little but different ball game.

Ed, I know you have been around the block and raced these cars a long time (as have I), but the racing you are involved in, is 30" tire stockers, wheelie bars, limited suspension rules and the like. I have never seen any of them lower the car to the point that stock suspension racers and us wanabes do. If you lower your car over the tire to tuck the tire (talking more than a simple cut coil in a spring), how are your LCAs not running downhill (if looking at them front?) and thus failing to driving the tire down/planting the tire?

I am not really arguing as i just want to hear some other arguments. Stockers have a way of doing things either because they dont feel the need to slam their cars down over the tire trying to look like a pro stocker or that they are very limited by class rules. stockers also love those huge wheelies sitting on the bars through the 60'.

As I said, John, the torque arm plants the tires. As far as I can tell the upper & lower arms are just radius rods. All I got out of "LCA" brackets was chassis bind.
Wanting the back end to rise has been proven wrong. Nobody does that anymore. Well, maybe here. Not where I race.

Somebody mentioned a 1.27 60' was a 1.40 with the wheels up. I don't know what mine would be with the wheels on the ground at 60', they never are. My 1.20s are with the wheels up. The 60' beams are. 8" off the ground. If your wheels are higher than that your. 60' times start with the beams seeing your car somewhere along the rocker panel. If you are straight up, it will be by the rear tires.

I went back and reviewed all my time slips and found that I ran my best 60ft yesterday at 1.48. The brackets are not going back on my car.

Ok ill believe 1.29, Not a 1.20 big difference to do that, about 400 H.P. more.

It carries the front tires well above and past the 60' beams all the time in the 1.20s. Not the only car doing it. I never said it went a 1.20.
If whatever you have won't, you need to get to work. Mine is only a 600 hp 350". It certainly would not take 1000 hp to go a 1.2zero. That is just dumb.
Just what do you have? What's your real name? Hiding something?

Ed from your post you have no idea how these cars work and shouldn't give advise to anyone. The lower control arm is extremely important in relation to IC and where it is located laterally and horizontally ride hight is a huge influence on this when you lower your car it makes the lower control arm higher in the back IC moves way foreword and in some cases never intersects you ALWAYS want the rear of the lower control arm lower then the front this is why you need to relocate the rear of the lower control arm when ride hight is changed my car has constantly ran 1.11 60ft and has been 1.10 on a 275-60-15 drag radial I don't care if you took the 350 out and put a 800 ci big block in your car it won't 60ft without huge tires to mask your chassis problem
