Which will get to the end of 1/4 the quickest

I can't wait for spring.
I didn't get a chance to get the car out of the garage last year, so I don't know what affect tweaking the front end will do. It should help the 60'. The front end will now have a chance to rise, it was stiff as a board before. You couldn't push the front end down much at all.
Also the muffles are old restrictive hookers I think, and at 2 1/2" are probably causing all kinds of restriction.
As for the weight of the car. I haven't a clue. There's always an issue with the scale when I'm at the track.
I have also replaced the front bumper, it's now fiberglass, and I also chucked one set of brackets, didn't think I needed both of them. That should get a little bit of weight off the front end.
