Car Unstable Under Full Throttle

Does the same sort of thing happen under braking, any instability with or without noise? Looking at the bump travel side of suspension movement here.


Norm

No instability under braking from my observations. My nose doesn't really rise under acceleration either. At least not as much as stock.

New rear tires, wheels/tires balanced, and aligned. Solved it all.

I am having the exact same problem after also installing Pedder Xa Coilovers. Did you ever solve your issue? My car feels the same way you are describing.

Might be worth a try for sure. But my tires do look good and my wheels are balanced. I may take them to the tire shop just to be sure, but this was not an issue prior to the BMR suspension setup install and Pedders Coilovers.

What exactly from BTR did you install onto your car’s suspension system?

Did you get it aligned and time the bushings once you did all the suspension work? Mine felt "drifty" but once I timed the bushings, feels solid now

^^^^ This. You have to "clock" the bushings after lowering the car, AND get a good alignment on it to correct the problem. Just because the tires look good, and the wheels are balanced, won't make a difference in how the car drives under heave acceleration..
