I was perusing the www yesterday and ran across an add for Coventry Wheels. Supposedly custom made for your bolt pattern and offset. I am not a big fan of the chrome 8 spokes on my 04' LS (impossible to clean the rough parts)
Has anyone ever used these wheel types? Secondly, what is the stock offset on the 17" wheel? Third, is there a way to re-calibrate the speedometer if you increase wheel size to an 18", or is it simpler to just decrease tire diameter?
Thanks all.
P.S. Happy Thanksgiving

The added tire size are 18 inch from the stock 17 inch. The Coventry wheels are 18 x 8 42mm offset (front) and 18 x 9.5 25mm offset rears. Anyone have the stock offset data for an 04' with chrome 8 spokes??
