I've about decided to get the black FR 22's but I read they have a noticeable impact on performance. I haven't seen though where anyone has times posted to quantify the difference. Anyone run these at the track yet to have a real world before and after time? How about 0-60? I dont go to the track that often and plan on keeping my 20's but hate to loose a really noticeable performance where I think our Jeeps are the most fun.

If it's a heavier wheel which I would imagine they are, they will affect performance. It's more rotational mass. Perfect senario would be..... new wheels and tires are same revs/mile and same weight, then there would be no performance difference. If they were the same revs/mile and a lighter wheel, then you would see some gains. If they were the same revs/mile and heavier, you would see less performance.

It's all about rotational mass like Harry said. Lighter the better. 22's are more for looks not performance.
