Encourage them to copy or very closely imitate the internal shape of the factory unit. It is designed/engineered and tested to produce desirable fluid flow and lubrication. I've seen other units create very poor flow with modified internal shapes.
Well, I suppose alternatively they could embark...
Finally got some as close to "apples to apples" pics of the before and after FMI front leveling collars. It really seems squatted out a bit a lot of the time I examine it, and despite the front fender gap being larger than the rear, it is pretty darn close to level. I have a bubble level app on...

Removing the PC in the counterbores would be a huge hassle and would likely make an uneven/low quality surface.
Thanks! I'm not too fussed on a bit of additional maintenance, esp...
