Re: Ideal size for aftermarket wheels?
How much speedo correction do you have to make with 19's in the rear? After really struggling to find tires for my Shelby Series 1's I'm thinking of a change as well.

Ideal size for aftermarket wheels?
Quote:
It depends of what size tires you decide on in 19?. Here is an example using the tire calculator to get as close as possible to stock size overall diameter. https://www.tyresizecalculator.com/ https://tiresize.com/speedometer-calibration/ Image1648726660.741177.jpg Sent from my iPhone using ZR-1 Net Registry

Dom, Do you use a GPS speedo and compare it to your car speedo to figure out the difference? Sent from my iPhone using ZR-1 Net Registry

With the speed sender gear set I have installed the the speedometer error is within 1 mph of actual at 65-75 mph of road speed. Sent from my iPhone using ZR-1 Net Registry
