i just ordered gram lights 57s in bronze and they are 18x8.5 in front with 245/40R18 and a +30 offset and the rears are 18x9.5 with 275/40R18 with a +22 offset. with this affect the odo or the speedo or will everything work just fine.

 

your VDC may kick in. just run with VDC off. it's a total waste in my opinion.

 

what is the waste? with vdc off or my rims????????

 

He is speaking of the VDC.

 

This statement is unfounded. Why would the VDC kick in? The tires (front and rear) have almost the exact same rolling diameter as stock. You will have no problems. I run 245/45/17 on all four when I have my race setup installed. I've probably put 3500 street/city miles on the setup and the VDC has never acted unusual...

Sorry for my griping, but I've heard too many people say that "the VDC will be messed up" by using alternative tire sizes, but I've never seen anyone actually say they've experienced this. My best guess is that the further you deviate from stock tire diameters, the further the VDC will be from optimal in behavior AFTER wheel slippage is detected.

1001 - I can't speak to whether the offsets are right ('cause I just don't know), but as far as tire dimensions, you should have no problems...

 

Same sizes I'm running *see sig*. Diameters are the same, car doesn't know the difference. Drive it every day and track the car using those sizes and ever had an issue. Looks great on there...roll with it.

 

note, i said may. also, my VDC kicks in with my 275/30/19 setup. i just run with it off. imo, VDC is bulls.hit. you can't use your car to it's full potential with it on.

 

thanks to everyone who replied. after i put them on i'll put up some pics. should be getting my fronts today and my rears tomorrow and then tires next week
