What’s the diameter of the HB racing pistons? How do they compare to Mugen?

All good but $26 for 4 pistons is a bit much to be honest.

Anyone else notice the plastic insert "wrinkle" when you tighten the nut to hold the piston in?

Do you mean the flap or the bushing?
if it’s the flap, you have the piston upside down. If it’s the bushing, you’re over tightening it.

The piston is installed correctly... and it's not over tightened...

Since there are no pictures to show how the pistons are installed and how the valves are wrinkled, I can only tell from my own experience that the installation instructions that come with the pistons are not very clear, and I installed the pistons upside down for the first time and was wondering why the valves got all wrinkled. Then I watched the instruction and videos from MIP web page again and noticed that the flat side should be facing up, not the side with "MIP" text, after that the valves were nicely flat. As said, I don't know if this is what happened in your case, but worth checking one more time

maybe post a picture because I don’t know what the issue could be then.
i don’t have problems with my pistons, so I suppose something went wrong during assembly.

I had the piston upside down. MIP text goes to the bottom. Flat side up.

You have the piston right side up? Flange bushing ontop, right?

See above pictures.

The flange bushings was installed correctly. However, the piston was installed backwards. There is a recess where the kit washer fits into the piston. It’s unlike the kit pistons which has the piston set on top of washer. With the MIP pistons the washer actually sits recessed into the piston. Very easy to make this mistake.

I ran these yesterday in a race, and am pretty happy with them. They seemed to keep the car a bit more stable

I agree
