Looking to get some XXR 526 wheels. Need help
Ok so I've been reading for hours about backspcing and offset to the point of total brain meltdown. I'm wanting to get some XXR 526 wheels, but first need to make sure I have everything right. For the fronts I'm getting 18x9 with a +25 offset and 5.98 backspace. So if I understood correctly from what Iveread, I would need a 1" spacer for wheels to fit correctly. For the rear they would be 18x10.5 with +20 offset and 6.54 backspace, so I would need a 1" spacer as well.
Does this sound about right?

I have those wheels. You will need a 1.25" spacer up front and either no spacer on the rear and just have to massage the fender wells, or get a small slip on spacer.
Also, get the larger offset wheels up front. 35mm I believe? This will keep the hub from interfering with installation.

No wheel poke, they fit almost perfect. Massage the inner wells a little and you are ready to roll. Car is lowered with springs that claim a 1.75" drop all the way around.
