ITS Brake Ducting - Rear

[BeerBudgetRacing]

I'm considering replacing my rear aluminum drums with the all steel. Some people have said the alum will warp, etc.
Since the aftermarket primarily supplies steel the are considered the replacement.

FYI, there is a new supplier of the aluminum drums in the last year or so.

Looks like the site on that thread no longer lists them, but a quick google search shows a few other sites that have them listed- all on backorder. Thus I'm just posting this for information- not sure how far you'll get with it.
