How much will adding 16 lb to my car affect ET/mph(rotating weight)

Hmmm, that is something to think about. considering that these tires are a Recap. vary good chance that they don't have the same role out.
will have to check that out soon.

I added a lot for load on the L front torsion bar when i installed my new SS Spring. taking 3 turn out and it goes straighter. was a mistake on my part when i re did my front suspension last year.

But the role out i haven't check on these cheater slick as well as my regular slick. How ever both tires swing the *** end to the right, when doing a burn out. So i still thing the t bar adj was a good idea.
We will see on Memorial Day when i go back to my slicks.......

If that’s the case, you need to make a perpendicular line about 50 inches forward of the axle centerline and measure the wheel base to that line.

If you try and measure the wheel base up to the front spindle you can be off enough to skew the results.

You need a couple of plumb bobs and that square. Just drop the plumb bobs of the center of each axle and then make a mark on the floor (thats why I use tape...Id end up with a hundred marks on the floor, plus it looked like crap) and then get your perpendicular line and measure each side to that.

It’s possible the axle isn’t square in the car.
