Default Steering wheel wobble during braking

After installing steeda sport springs and koni sport dampers, my steering wheel wobbles during hard braking. I dont remember the wobble being there before these components. Is there a solution to this? What could be causing the issue? Im pretty sure it isnt the rotors but im not 100% sure.. they look fine as far as i can tell. Whats the best way to check if its the rotors?


Are new rotors a good investment anyway? I may upgrade the front rotors if they are worthwhile over stock and not too expensive. I have the non-brembo brakes btw.

You may want to check your installation of those suspension upgrades and make sure nothing is loose, before checking those rotors.

Is it a fairly rapid shimmy at the wheel or a kind of slow back and forth tug?

Did you have the same wheels and tires before you noticed this? What offset are the front wheels?

Did you check and possibly reset your alignment?

I had that problem on my 2011 and a pair of Girodisc floating front rotors fixed it. Nothing else made any difference.

Only time I've experienced this was when I had warped front rotors.

hmm, does your 2014 not have this issue? and did your 2011 have brembo brakes or standard?

2011 was a Brembo car. 2014 is a GT500, which is a totally different animal altogether. I'm running 3 degrees negative camber and the braking is straight and true from 140MPH down.
