05 M6 cam and headers car 450WHP. Does anyone know if polyurethane control arm bushings will help with wheel hop. The problem is the worst with street tires. It’s much better with drag radials.
I would look at the trans mounts first. Hinson makes some good trans mounts out of polyuerathane. Shocks can also help how old are your shocks? Finally and someone may know more about it, I think they may have changed the rear leaf spring in 2007 to be a little stiffer to help control the wheel hop.

Thanks for the idea on the trans mount I hadn’t thought of that. It’s pretty good at the drag strip with the drag radials on it but just really annoying on the street. The shocks are original so maybe that’s a good idea also.
DTE brace ... less PSI in the tires? I don't wheel hop on street tires (just spin) or Nitto nt05rs' (they just spin on the street as well). Remove front sway bar as well
A transmission brace does nothing to help wheel hop. The purpose of that is to keep the transmission and diff from breaking apart under high torsional load (high powered, high traction cars). As mentioned, polyurethane (slightly noisier) or delrin (a bit noisier) rear control arm bushings or spherical bushing replacements (very noisy) along with polyurethane transmission mounts (preferably Hinson's) will help cure wheel hop, when used along with decent shocks.
Even with Hinson mounts and spherical bushings in my car, I recently experienced some wheel hop/tire shake at lower tire pressures, but after installing an ECS Torque Tamer, that cured it. It's a wonderful little device that everyone who drag races should install, although it does transit a bit of vibration from the torque tube to the chassis..

I destroyed a diff when I had wheel hop coming out of a hairpin hard at PBIR. It is the diff and trans flexing and shaking the rear causing the hop. (You are describing wheel hop in your description of what a brace does). After a new diff and a ECS brace I now have zero wheel hop.
BTW this is the description of the ECS diff and trans brace. It describes its use and why it solves wheel hop.
