No clue if the Quaife and 3:73 gears helps or hurts.
Sorry I can not be of more help.

Wheelhop is the result of the tires alternating between spinning and then momentarily hooking thus causing violent tire and driveline shake. The end result can be catastrophic. If the car can overpower the tires and just spin, you will not hop. If the car dead hooks and is a manual trans, that may be detrimental too by overstressing the drivetrain.
Street tires and DRs tend to wheelhop much more than bias ply tires.
Thicker sidewalls and lower profile tires tend to wheelhop more.
Too quick of clutch engagement and lockup without slip can produce wheelhop.
We have successfully used adjustable QA1 coilovers which are a great product and help mitigate some traction issues but coilovers cannot prevent wheelhop.

very interested in this also. I have 560rwhp and putting re-11"s on this spring and rps clutch. Do the ecs tranny brace help? Have f55 ride all else is stock. 3lt trim. Street run only so far. No wheel hop just spinning stock gooodyears 12000 miles.

You will most likely overpower your tires every time on the street without inducing wheelhop due to your power level. A well prepped track may cause an issue depending on your launch technique but more often than not you will more than likely just spin with those tires. As for any brace, we have seen breakage on vehicles both with and without them; therefore, we do not run one.

From my understanding, the tranny brace does not eliminate or even reduce wheel hop. It acts as a barrier once the carnage occurs, limiting the damage to only the rear axles/diff, hopefully saving the trans.

So it looks like no one thing will stop it or even the combo. old days it was traction bars bolted on to leaf springs. Much more involved now but I know some on this board have mastered this but at what cost. Is trying to stiffen the rear-end the way to go? Rear mounts stiffer sway bars, heavy duty rear hubs.Trying to get my parts bought before spring. Will call Doug Rippie on Monday for his thoughts. Will post after I talk to Doug maybe help others as well as glad Mean Joe brought this up.

Is this on the street or track or both? Is your car an auto or manual?

Cause and result highlighted. The cure is to provide a smooth application of power not to exceed the maximum traction available. The problem is determining the degree of traction, since the available power that causes it, will by definition be excessive. With a manual car, the primary control is the driver's input.

What I have found to be some factors in wheel hop........
~Temp of the surface in relation to temp of the tire, a colder surface seems to elevate the problem
~Tire compound and condition/age
~Suspension design, A-arm bushing deflection..etc
~How the power is applied

and i will add a dew point within -5* or higher of the actual air temp

So the real answer seems to be that it's driver related more so than anything else. Thanks for all the good reply's. I guess I just need to give it a bit more gas. EEEE HA!!!

its driver related to the condition's but without the basics, bigger sidewall tires lower air pressures and good shocks better bushings tires warmed you will still get rear breaking wheel hop

Good call on all those points. I have a 2013 GS. The car came w/GY super car tires. They were RF tires. TOTAL JUNK! I had wheel hop from them on any hard acceleration. No matter what the ambient temperature was. Especially when it was cold out. I switched to Michelin Pilot Super Sport tires, and the wheel hop is gone.

Took the 13 GS 6 speed out today, 44 degrees in Ohio. Wheel hop like crazy. This has been happening for a while even in the summer. This can be good for the car?
