This stage 3 trac bite product does work to keep the rear diff and cradle from flexing on take off. Having that said, there will be a diff noise that is heard in the car which is normal. This is worth it when you have a Roush supercharger that puts the horsepower at 750 at the crank! Besides that this is a 2023 s550 Mustang and this product fits the 23 model year. I would recommend this product to anyone.
Wheel hop, sloppy loose feeling drivetrain/ rear end, no confidence at the track. GONE. After having other SPE parts on my truck, I had high hopes for this. My 2016 GT feels like it is on rails now, and the overall driving experience surpassed my expectations. Vertical links were a little harder than the rest of the kit to do but still no big deal to get done in a night after work. 10/10 SPE!
Great look out of the box, even better fitment. Everything went together with ease. Helped a TON with wheel hop, and putting the power to the ground. I personally run this on my 1300+ whp twin turbo car, and it has no issues cutting 1.20 60's at the track as well as my 900whp SC s550. 10/10 recommend!
