Fyi, Changed To The Wider Birel Steel Bumper On A R31 And The Weight Difference Was An Additional 2.80 Lbs.with Brackets

Thanks Dale for the added information. Have you tried the plastic bumper at all? I am not sure if it is heavier or lighter than the steel one.

In general, other than the weight difference, is there a tuning preference when choosing between the plastic and the steel? More knowledge or workability with one as opposed to the other?

At this point it is up to each driver to test. It will influence each differently. There is no magic answer.

It is a matter of preference.
