Pics to show reiforcment in porka steel arms .
 

I was reading on here somewhere that the porcshe steel 944 arms had reinforcment ,but no one had cut cut one to find out .I was comparing mine for narrowing and noticed an extra plate behind the rear inner bearing.I had looked at johans tech feature and thought this extra plate could be a real pain when it comes to separate the hub from the arm.The extra bit extends into the arm.
