FD - Adjustable sway bar style: slotted or holes?

Most people are familiar with the Tripoint-style adjustable sway bar. ProParts USA now offers the same sort of bar via Mazda Motorsports, however the arms are slotted instead of having the 5 holes. Both styles are pictured below.
Should the ProParts' slot work effectively, provided the bolts are properly torqued? Or would it be better to drill out the 11mm slot to 12mm in a few places and use a metal 10->12mm bushing around the bolt?

I'd torque the **** out of them and at the end of the weekend or trackday or whatever, take a look and see if it slipped at all. I like your idea of boring it out a tiny bit though if there's a problem.

I also have a question for TP or RB adjustable swaybar owners: Do you have dual oil coolers from an R1/R2 and if so does the swaybar interfere with them? I remember it being pretty tight when I installed the oil coolers.

(Sorry for the semi-threadjack, and nice find!)

I'd be afraid of the the links sliding/slipping with the slotted arms. Maybe some sort of spacer could be fabricated to fill the gaps?

I've never used the slotted type, but I'd have to think if the links are torqued correctly it shouldn't slip. one way to find out though! I'd try running as-is and if you experience issues then look for another solution. No point in trying to fix something if it's not an issue.

They're fine slotted.

Never had any interference issue with the Tri-point and R1 coolers and lines. Not even close.
