Lighter Wheels Aynyone?

[jbrumley1]

Has anyone here with 20" or 21" wheels ever swapped to a lighter wheel for less rotating mass?  Maybe Welds, etc., for faster 1/4-mile times?  If so, by how much did it improve your ET?

Is this a daily car or are you planning to race it?

 

You will not find all that much improvement, however there are multiple ways to make a wheel lighter, just to name two (2):

1.  Use a smaller wheel with a smaller tire

2. Lighter, less material in the wheel to reduce weight.

 

Unless you are willing to spend some serious cash, buying lighter wheels may also result in wheel damage from pot holes, curbs, etc. that your OEM wheels would easily survive

The lighter wheels were an aid in handling. AKA road racing. It does this

by reducing unsprung weight, so the suspension follows the irregular

road surfaces better.  Now if you want to go around corners.........

Thanks for your comment's fellows.  I've found a few great quality wheels and tires which would shave off about 25 lbs. from each corner.  So, this weight reduction woulbe equivalent to about 500 lbs. of dead (un-sprung) weight.  My goal was to lighten up the vehicle a bit before doing more serious upgrades.  Have decided against the wheels for now, since a turbo upgrade kit would be about the same price.  I'll later buy a set of 16" Weld Drag Lite wheels and tires for the track.

 

Shooting for somewhere in the ballpark of 400 AWDHP/425 AWDTQ.  So far, I've done the Livernois MyCalibrator tune, TurboSmart 50/50 BOV, NGK LTR7BHX (95605) 1-level colder Spark Plugs, 170* thermostat, and aFe CAI PR5 Pro Dry drop-in filter.  Going forward mods are going to be CVF FMIC, then, upgraded turbos.   Anything more and I'd have to upgrade the fuel pump and injectors.
