Just FYI, this is another one of those items not covered in the rules, so technically *could* be illegal. Rules do not say that IMS bearing upgrade to a ceramic bearing is allowed.
It is normally accepted that these are allowed but you never know.
If you decided to change out sealed steel ball WHEEL bearings you would get labeled a cheater. But if you replace a steel ball IMS bearing you are considered intelligent and improving reliability. (even though wheel bearing fail more than IMS bearings)
Heck, even X-51 or EBS pans are not listed as being allowed modifications because they are not "deep sump" pans.
