Wheel offset equal to spidertrax spacers?

[EH007]

Here's my question:

I've been looking at JA's website and love the way his spidertrax spacers look on his '08 Sport. It seems that a 1.25" spacer looks just about right to bring the tires/wheels almost flush with the fenders. See his website page here:

Now here's the thing. I don't know for sure if I want to go with the spidertrax spacers and I might want to go with new wheels. If I do that, then I want to get an offset that will bring the wheels out to the same position as JA's spidertrax spacers bring his stock wheels. I'm considering getting the Mickey Thompson Classic II's, but I don't know how to figure out if how much more the offset of those wheels will be compared to the stock wheels. Does anyone know how to figure out if the offset will be similar to the stock wheels with 1.25" spacers?

Here are the three choices for the wheels in 17" with 6 lugs:

Mickey Thompson Classic II 17X9 6-135mm 5.5BS


Mickey Thompson Classic II 17X9 6-5.50 4.5BS


Mickey Thompson Classic II 17X9 6-5.50 5.0BS

Also, does anyone know if the Mickey Thompson Classic II wheels are hub centric? I'd prefer a hub centric wheel to a lug centric wheel.

This thread will help as will this website.

It'll take some basic math but you should be able to get it. IIRC the stock rims with a spacer yielded a slight negative offset. The 4.5" backspace on a 9" rim is probably closest...
