Remove spare and trunk junk for dragging?

Nismo221

So pretty much your saying the small amount of weight your talking about, I think its 50 lbs, does not make that much difference? Or is it that with the added weight we are slower but get better traction. And without we are faster but have less traction. But the end result is about the same? I would like to look at time and mph. The times may be close but I bet the mph are faster in the cars with less weight.

I'd say it's more like 30 to 35 lbs.

I looked through my time slips, can't really find any two that would clearly show a significant difference between spare vs no spare.

I just noticed you have a Nismo, it will probably be more difficult for you to launch. Stiffer spring rates will hinder weight transfer. You're probably better off leaving the spare in there and relocation the battery to the rear. That's my 2 cents.

To answer you question, I'd say the spare does make a difference but not as big a difference as other factors. On any given night, (whether I have the spare or not) my 60ft time depends mostly on:

1) how good the track prep is
2) how good of a burnout I did
3) how quickly I floor the gas pedal once the rear tires grip and the rear squats (if i don't get that part right, i get a ton of wheel hop.. no bueno)

hint: tire pressure also helps
