Seriously appreciate the advice! I didn’t want to spend money where not necessary so this was a huge help. I will look into the ZLE radius rod as I’m currently using the Hoosier track attack pros.

But, TBH, as for the arms, if you are tracking, all you need is the rear upper control arm + lockout and the rear toe rods + lockout. A couple reasons. One, those two arms with their lockouts, you get rid of the unreliable torque to yield eccentric adjusters. Two, those two arms will make alignments super easy. Three, the OE upper and lower traction (trailing) arms are just fine with their rubber bushings. IMHO, unless you are full tilt racecar time trial, you don't need much more than that. The cost of all the SPL arms and the knuckle sphericals is not justified.

The BMR diff lockout is not really needed too. Poly will deform with time and heat. The OE bushings are just fine.

I will add as far as the front low hanging fruit, go with the ZLE radius rod (forward/diagonal lower control arm). It's bushing is solid unlike the FE4 SS 1LE hydraulic bushing which can eventually fail with 3R or greater grip.
