    First time measuring and learning about fitment, so bare with me.

    I lowered the 5th gen XSE about 1.5 - 2". Current front specs show about 15mm of clearance from the fender to tire, 20mm from fender to rim, and 40mm from the strut to the tire. If I were to go with 19x8.5 with an offset of 38mm and 245/35R tires, I'd probably have to add neg camber, or drop an inch off the width, right?

    245 tires with 38mm offset is maybe pushing it? I’m currently running 245s with an effective offset of 42mm in the front and 45mm in the back with no issues. My gut is saying the extra 4mm offset will likely be fine in the front, not super sure about the backs because the fenders have more of a lip than the fronts

    when I get home I’ll slap on some spacers to test for rubbing, but the best i can do is +40mm because i only have 3 mm and 5 mm spacers and I do not really want to stack them. Here’s hoping its fine though because I really wanna do that GR Corolla front caliper swap and that will need bigger spacers for sure
