What is the spacing? how many lugs? what is the offset? any other info I need to find rims which will fit on the 2003 CL type-s. Thanks

 

The stock offset is +55, the closer to this the better.
Minimun of +45 is recommended. But this can be flexible, depending on how wide your wheels are.. don't get one too low, otherwise you may have wheels that stick out too far..

Bolt pattern is 5x114.3 aka 5x4.5

Not sure what you mean by spacing.. I'm assuming clearence..

if you're not lowered or planning to lower, you can get just about any wheel you want... but you more than likely won't be able to get anything larger than 19x8 and nothing smaller than 16x6.5..

As for tires.. that's another story.. decide on the wheel you want first (diameter, width, offset), then you can choose the tire..

 

Might I offer a simple suggestion here please?? This is a HUGE area of talk on the board, so do a search and you 'll see that which you seek. Second, look at the sigs, go to the following for prices (for a start)

www.wheelmax.com
www.tirerack.com
www.discounttire.com
www.precisioninstallations.com
valleytire.com

That'll get ya started. Tirerack has an interactive program that allows you to see what fits on your car in the color of your vehicle as well.
