Got a set of groupA fit rl7 wheels
Basically, i got a set of the 'conversion nuts' so i can put them on using std studs.

However, i put the nuts on and tighten and the wheel is still slack.
What i think is there should be a steel insert in the wheels maybe?

Any thoughts or ideas? needing help here.
