I want to do a write up an the DIRS brace . This thing is the cat ass( pun intended lol) . I had the V2 for the 2018 and up on my car originally and to be honest I was quite happy with it . But once I seen the DIRS of course the wheels in my head started turning . Did I need it of course not I don't make enough power to warrant it but I had to have it! Thanks to Mopar ( site member) he set me up with one of the first production units . I like that it's solid aluminum and I think the best part is the bushing in the center I think this will take away some of the ridgitness ( is this a word? Lol) over the original brace and help stabilize the diff. I looks very intimidating from behind that's for sure . I will say this without a brace I got ridiculous wheel hop . In fact so bad the drive shaft hit the mid muffler ! No more wheel hop for me and hopefully a diff that will stay put for many years . The only option I would like to see is a polyurethane bushing instead of a rubber one .

Thanks Per4Mance Development for the great product I couldn't be happier! It was on my car for my 9 second pump gas pass!

I think for most people the V1 and V2 braces will work perfectly . I think the DIRS if needed for big power cars ........or people like me who has to have one

A diff brace is going to help tremendously for wheel hop.

I wonder if the BMR diff lockout bushing inserts could be used to firm things up a little?
Ohhhhh I never thought of that . They also have poly bushings . I may look at that over the winter ...

I have the TBA currently and it still hops. I do understand that tires and roads are a factor so was curious if this was a better option.

That's surprising to me. I have used every version of P4D brace on my car and I'm currently using the DIRS, and my wife has a TBA brace on her Hellcat. I can't honestly say I've had any wheel hop on either of our cars since installing diff braces.

Are either of them M6's? It's likely the shoes could be the issue

If you decide that you would like to tighten that bushing up (you mentioned a poly bushing) there is a way to do that. The BMR diff bushing set uses steel shims in the rear bushings. They are inserted into slots in the rubber isolators that are in the cradle in the rear. I’ll include a picture of those in mine. It looks like the same bushing. They simply pound in.

I have no wheel hop in my M6 with over 900whp but I haven’t had it to track yet (I doubt it will matter). I also added cradle and diff bushings along with full rear suspension upgrades at the same time so it was drastically different for the better. I may not be the best example as to how this piece does singularly but I wouldn’t be without it. It’s one heck of a unit.

I'm not having an issue yet......... But it's good to have options in the future.
