29.5 in tall.. Traction was pretty good with the heavy's... Just thought, shaving 30+ lbs per corner would help.

I've been wanting to run this test on a prostreet truck for quite some time. I'd think results would differ with a lightweight diesel truck (4500 lbs) vs. it's gas counterpart.

Hahahahaha ^ Did I see the test on a carbon fiber driveshaft here or elsewhere? I know it was on a truck in California. Picked up 7 or 17hp. Interesting results as well

I haven't seen a great correlation between unsprung weight reduction and dyno "gains". Usually the track will show better results. Just my experience.

Tenths is a big term in drag racing. Thousanths or hundreds, are more common with rotating weight changes.
However iirc when we did this same test over 10 years ago I seem to remember .008 -.010 was what we dropped in ET. And gained couple mph... Point is it did help

Well, sort of...on my duramax I would go from running a 12.0-12.1 to solid 11.80s by just switching from my 20s with street tires to pyos and drag radials.
