I'm liking Weld's new forged offerrings

EDIT: Funny how the reference guide posts 11 lbs... Hmmm...

22 lbs is for wheels and tires combined.

I think that is great. Shaving 22 pounds off of dead weight wouldn't seem like much. Losing 22 pounds of rotating mass is HUGE!

See how many wheels there are on the market that weigh less than that, and look at how much they cost.



Please don't ruin a ZL1 with something gaudy.

Forgestar F14s weigh in at 27.2 lbs for a 20x10 and 28 lbs for a 20x11. a set of them will cost you about $1,850. That's a damn great price for some super light wheels. They are about 13.6 lbs lighter than ZL1 wheels.

I shaved almost 70 lbs of rotating weight when I swapped from the stock 20's to my 18" F14s (that jumps to almost 90 lbs when I put my skinnies up front) and it is by far THE BEST performance mod I have ever done. My car brakes better, handles better and definitely accelerates better.

Have any pics with it widened? Never seen that look before

At 20x10 & 20x11 how much do you think you are going to be able to widen them? They are probably at the max width, maybe you can get another 1/2" before they stick out.

The tires probably are the same weight or even more.

Oh, by the way Christmas is only a few weeks away and a set of 505a rims would look really good under my tree (Hint,Hint)

I had these on my GTO, 19x9 front, 19x10 rear. Beautiful rims but an absolute PITA to keep clean and polished. The spoke design and raw polish finish make it a bear, even with polish lock and other similar products. I ended up selling them after 2 summers of use for only an $800 hit.
