Good point. I will have to look at fiber gaskets. Thanks.

I got a fresh new diff cover and a stack of gaskets off rockauto for cheap.
I think a new smooth differ cover and a good wire wheel cleaning of the housing will be the trick to get a clean release of the gasket each time, plus about every few race if you pull it to check it shouldn't "set" and harden to where it makes a mess to clean up. I'm liking this a lot better than rtv.

For clarity, you don’t have to add a drain plug to the cover, you can add it to the housing. The GMs have a nice cavity right at the bottom that is perfect for this.

Agreed it's GM biased towards the rearend....of the field.
Had to make a change after the 2016 results in Texas with Fords winning 83% of the podiums, every Toyo race, and every fast lap of the weekend.
2017 got it back in line with 2015's 72% Ford podiums. For 2017 Ford had 75.36% of podiums, every fast lap of weekend, but GM did get a single Toyo win.
2018 so far is right in line (but revisions may need to be reconsidered). Fords have won 73.33% of the podiums, but only 7 out of 8 Toyo races, and they have 3 out of four fast lap of the weekend.
But to keep this on topic are we allowed to run an aftermarket aluminum cover? What if said cover has some bolts to help the carrier bearing in the ultrastrong GM diff? What if the bolts are backed out so they don't provide any support? At least we are allowed to upgraded to the superior Ford 8.8 or Ford 9" with better posi and gearing options. Guess I need to do that swap instead of adding a diff cover with a drain.

That's a negative on the aftermarket cover, this has come up before and gets shot down every time. There's an RCR thread on the national forum about this very topic from a few years back.

I know some seem to think Bryan is the only one who can hustle a 4th gen, but he's not completely ruling the roost back here. I'm not seeing any disparity in the platforms based on my observations in RM, TX, and Nats. I am faster than I drove at Hallett this year. My weaknesses are launching, learning a new track quickly, and managing traffic to the extent that Michael and Bryan do. The latter 2 hurt me at Hallett and, quite frankly, getting all the way to my 10/10ths really takes a lot. I have to be pretty relaxed to get that last little bit on some tracks and that isn't exactly easy when there's 20 cars breathing down your ass (or 1 Mosty). I think some people believe they are at the limit and they're not realizing what's still on the table. I haven't touched my setup in years, I just drive. If it feels pushy, I change my driving and if it feels loose, again, I change my driving. Next event car usually feels fine. Typically when my car is off, so is everyone else's so it's relative.
