Just put new KMC Stealth 20 inch rims on my 4.2. Man have they slowed my acceleration. I have a Hypertech chip and an FIPK and it still drags. Just some information for all you low riders out there that still like to go fast. But from my experience the last few nights it makes it easier for the ladies to catch me.

 

when you got your new tires with the rims did you go up or down on the outer diameter? The size or the rim has no effect on acceleration. For example if you went from your 30" tire to a 31" yes you would slow down a little, but if you went the other direction from a 30" to a 29" you would gain acceleration.

 

Ah Man! Don't even start with that! I'm going to be getting some 20's within the next month! In fact, I'm not lifting my truck because the V6 wasn't going to hang. That's why I'm going with 20's! But I had no idea it would slow it down as well!

BTW, the stealth wheels are pretty sweet! But I want something with a little more appearance to them. Something like this....
