60' vs. front end
At what point (60' wise) does the front end of the car become lofty. I cut a 1.62 the other night and the front end felt glued to the track, is that a good thing? I feel like if I leave any harder my car will spin. However, I am installing lca relocation brackets thurs. I will also be trying the 200shot out, if it hooks then we'll be in business.

Keeping the fronts on the ground and cutting good 60's is a great thing. My guess with the brackets you will pull a tire and maybe get a 1.5X. I pull a tire with anything in the 1.6X range. This will haunt me as I get faster and pull the tires harder. Obviously weight transfer is good over the rears. With a good rear set-up (LCAs, brackets, TA , etc...) you will get this. But there comes a time when too much transfer equals yanking the tires too hard and loosing straight line acceleration. At that point you will need to adjust shocks and pinion angle and so forth.

I just want to know that the car is moving enough to transfer weight. It doesn't seem right with the swaybar on. I am contemplating taking it back off, but it does drive better with the swaybar on.

What wheels and tires are you running up front? With the bar in it will be more inclined to stay down since the suspension is not dropping the front wheels on launch. I don't drive with mine at all. But then again it only gets driven about 3k per year if that. I may put it back in though with the skinnies since they are lighter.

All I can say is then is check your pinion angle. Do you have an aftermarket TA? As long as you are hooking you are OK with keeping the fronts on the ground. What kind of times do you run? What power level? What stall? Are you dead hooking or do you have spin? So many factors in a good 60'.

I think it is mainly the converter. It's a 3500 in a th400, no trans brake. The car is geared 3.50 with the 325 mt radial. It felt like it dead hooked the other night on the 100shot.(1.62) I asked the opinion of someone I feel is a seasoned performance enthusiast, believed that the converter needed to be larger. And the pinion angle was set at -2.5.

Pinion looks good. 60' seems week if you hit the 100 out of the hole. Those tires hook like glue. 3500 is pretty loose especially on the 100. It will flash higher on the 100. The gears may be holding you back. Or you may just have a very inefficient converter. I 60' in the mid to high 1.6Xs with an M6 on about 360rwhp and stock clutch. Autos tend to 60' better. So your 60' is down IMHO. I don't think it has anything to do with weight transfer. Does it seem like your traps are in line with your power level? If those are down too then maybe you are not making the power or the converter is not a very good unit. How about the trans? Is it built? Could be slipping.

I've cut a 1.57x 60' time and my front tires seemed glued to the track as well. I've got no weight reduction, even the A/C is still on the car as well as some stock rims. I feel like I'm hitting the tires pretty hard with my PT4000 converter but since my motor is still stock there's only so much power available. I've got the front sway bar removed so I guess there's some weight reduction that I forgot about. Oops. I'm going to pull some weight off the front end of the car and hopefully I'll start getting the left front tire a little light on the launch.

I am no expert, but I have done a LOT of research on autos. I recomend a 4000 nitrous converter with anti ballooning plates. If you do not cut 1.4Xs on the 100 shot out of the whole then you are way low on power or weigh like 5000lbs.
