ET difference - swap to lightweight wheels

Got some new Racestars for my other car and overall shaved about 80lbs off compared to the stock OEM wheels/tires that were on the car previously (55lbs off the front, 25lbs off the rear). Went with some wide drag radials and front skinnies (radials all around).

Car ran high 11's last year in good air. What kind of ET difference would I see from this if any?

I guess the "old" thing is -100 = .1
So you could be close.

Yeah, hoping for at least .1 off the ET.

I mounted the rims/tires on the car last weekend and went for a spin. I can say for sure the weight transfer is way better. The front end shoots way up now when I get on it with that setup.

Hoping it picks up from better weight transfer, less rolling resistance (front skinnies are 4.5" wide vs stock rims that were 9" wide), and less overall weight.

Rotating mass is the best place to lose weight. You should definitely pick up a tenth or two.

Track doesn't open until April 8th. Still got a few weeks to wait unfortunately.

Hoping for 11.40-11.50's in good air this year! We'll see! I'll update this thread once I get some passes in. Hopefully at some point in April.
