Cool, thanks. I'll give your setup a try as a starting point in a couple of days, we've got low-grip carpet where I'm racing.
The PDub 415 bumper showed up, and is definitely a big improvement over the stock bumper as far as hardness goes. It required a bit of chopping to make it fit right, but nothing too major. I'm waiting on the kydex part to show up from BRP to see how that does.
