Man Im still getting wheel hop. I've got the diff brace, bmr craddle lock out, and the entire aad kit.

[@StreetTunedJesse]

@@monty3927 lol what tire you running?

[@monty3927]

@StreetTunedJesse not so good Atturo tires. 275s

[@StreetTunedJesse]

@@monty3927 there goes your answer lol. Upgrade to a Mickey Thompson et street ss or nitro nt555 r2. If you’re on stock wheels

You need a Lift my friend

[@SpeedysGarage]

This install is actually easier with weight on the suspension, but yes a lift would be nice, I'm just spoiled by the space in my shop at this point and don't wanna give it up.

[@rxs20]

would starting the large horizontal/longitudinal bolt before the two smaller vertical bolts that pick up the nut plates made it easier to support and position the brace as opposed to holding the brace, positioning the nuts and starting the vertical bolts?

[@SpeedysGarage]

Maybe. It wasn't that bad to get them going, just had to hold my mouth right. I thought about doing as you suggest but I worried about cross threading the upper bolts inadvertently.

[@bwb8651]

That is listed as an optional way to compete that task in the installation instructions...

[@rxs20]

[@harleydream4u]

I never had "Wheel hop" from a rolling street start/acceleration... more loss of traction vs. wheel hop. Now at the strip wheel hop is an issue on these cars, Hellcats and Scats. I have the Per4mance Brace, but also needed to add the Cradle Lockout (BMR) and AAD Rear suspension... now that ended the wheel hop, the brace alone did not. Do you plan on the BMR Cradle lockout and the new AAD Rear Aluminum 170 setup?

[@SpeedysGarage]

This one with the wider tires would give me some chatter due to stick/slip gone now. I'll get more data at the track. I had BMR Lockouts on Go Man Go and they added a bit more NVH than I like so I'm going to try to avoid them on the 170.

[@harleydream4u]

@@SpeedysGarage I have wider, 315's MT ET R's on 20x11's out back... BMR does not give me any NVH, just does its job. Per4mance Brace, BMR Lockout, and the AAD rear was golden for me at the track. I do not race on the street... too many road warriors doing that making comical KZbin videos of their totaled cars. Best of luck with whatever you choose.

[@muscleonly1]

I thought it was not recommended to jack up the rear of the car using the jack on the center section

[@SpeedysGarage]

Just don't be ham fisted about it and it's fine. I use something soft on the jack to protect the fins.

[@joshreynolds729]

Differential independent rear suspension-DIRS? Or drag

[@sifudan9244]

what about warranty ?

[@flicksifyr6793]

No affect on warranty as far as im aware. Maybe remove it if your differential breaks under warranty. Those dealerships will find any excuse not to do warranty work.

[@Hunter-dv1qu]

How did you fix that p0850, coming from a forum about 6 years old, saw you had the same problem, was it the transmission itself having issues? How did it turn out? My car won’t park and flashes P on shifter, I read how it says you must reset it? I hope thats true

[@StreetTunedJesse]

Is it really worth the money for this? Or is it for some peace of mind. I’m on a 2.62 and haven’t had issues over 100 passes in.

[@Megatron797]

Absolutely worth the money. Especially if you track and especially if you mod. This plus AAD’s wheel hop eliminator kit is great.

[@StreetTunedJesse]

@@Megatron797 I have full AAD front and rear suspension. That’s not what I asked. What are the benefits , according to 90% who own it people buy it for peace of mind.

[@SpeedysGarage]

Kinda like asking is insurance for the car worth the money.

[@StreetTunedJesse]

@@SpeedysGarage that doesn’t even make sense guy. What does this $600 brace do for the car? Simple question . Does it improve traction or stability? That’s all I trying to ask.

[@SpeedysGarage]

I can't tell if you're just messing with me as I thought everyone knew about these braces, but the Hellcat diffs have a history of failing in dramatic fashion, especially at the drag strip. When they fail it usually takes out a bunch of other parts like drive shaft, axle(s), and does some body damage in the process. People have said repairs were very expensive when this happens. The primary benefit of this part is it strengthens the diff preventing the breakage, and adds some insurance in that if it does break the brace holds it together preventing further damage. Secondary benefit is firming up the movement of the diff which aids in preventing wheel hop. Hope that helps.
