DEMON WHEEL HOP AFTER DIRS 2-PIECE DIFF BRACE INSTALL

2985 Views 9 Replies 6 Participants Last post by  18demon
A friend recently blew the rear end on his Demon at launch at the local1/8 mile strip. So as to try to protect against the same experience, I recently purchased and installed a $550 Per4mance DIRS 2-piece differential brace on my Demon. Tracked the car the other day, hooked well and ran a 6.5, 108 mph, 1.4 60ft on my first pass, being near the best I've run with my no-mod Demon on M&H slicks. Second, third and fourth passes developed progressively worse wheel hop. Looking under the car at the track it doesn't appear anything broke. Curious to know if anyone with a Demon has had similar wheel hop issues after installing the DIRS brace? Might be time for some fresh rears, but I don't know if that might be the cause starting and just between such few passes and after a good first run. Thanks.

Wheel hop is cause by spinning and grabbing. Just don't spin! Simple no?

Your OWN example you had no issue at first when the track was on point. Nothing wrong with the car. It was the TRACK or your setup (tire pressure, burnout length, launch style and launch RPM).

SUPER IMPORTANT: Re Torque those 2 verticle 12mm bolts. DO IT!
Here is the best response to the issue.
The diff brace helps but is not a wheel hip eliminator. One can still induce hop if one tries hard enough.
