    As far as I know, the only option is to use a CV/GM PCM.

    I’m pretty sure there are lots of folks running the same tires front and rear with no issues.

    It'd be the ABS Module, not the PCM. I don't know of anyone who has actually done this though

    That works on 03A's which lack traction control

    If your have traction control, you can't run same size tire UNLESS you turn traction control button OFF every time you start the car. You must maintain 3-6% height difference

    I do this myself with the proper tires. I did forget that this was the case on the 04 MY.

    Even with an '03 you can get an ABS light flashing occasionally.

    I ran same size tires all around all winter long 2 years ago with zero issues. I only went back to staggered because I lowered the front and had to get smaller tires.

    For the longest time I was riding on 235/50's up front and 245/50's out back which is in that 3% margin we're "supposed" to stay out of.

    03A's don't care, 03B's will.

    I ran 235/50R18. 245/60R18 for 3 sets (including the good tires that were on it when I got it used)

    then I found out CHP sells their 245/55/18s with like 80% tread for CHEAP (I get rears for $100 installed)

    they are however too big for the front... and the front size looks silly on the rear.
    Im a gearhead with way too many vehicles...

    Im here to talk about my 03 Marauder. 300A/B (I have a weird mix)

    165k miles as of dec 2018
    Jmod, removed 2 springs
    flomaster
    tint and 2din headunit + bigger sub
