1 1/2 Iinch wheel spacers all four, GDSMOTU, #SPCR-0007, $69.99, Amazon.
For you guys planning on different rims, i have measured the stock rims, they have a offset of "0", So adding 1 1/2 inch wheel spacers is like a rim with -38mm offset. The point is negative offset moves the tire outward, offset is measured in mm.
