Default loose steering feeling after track days..

I feel like my steering is a bit loose after my last track day. The wheel is not nearly as reponsive as it used to be. The car drives straight when my hands arent on the wheel but I can whip the wheel 90degrees from one side to the left and right and there is a mushy floaty feel with minimal turning reponse, no more tight handling feeling. Also wheel vibration and road feedback seems poor. I have proper tire pressure in michelin pilot ss tires and swift springs on nismo shocks. I haven't checked power steering fluid but I can easily move the wheel at a complete stop with no noises so im not suspecting that. I've done a search online and seem to come up with tie rod ends, center link, alignment slipped swaybar loosened, etc.. any ideas? Car has 6700 miles but has seen some tough love @ the track. What do you think? Any ideas? Thank you...Happy Holidays

"Mushy" sounds like low fluid or bad control system to me. Worn suspension parts usually produce "hard" symptoms (clunks/thuds, dead spot in steering, &c)

Check into a power steering cooler.

Sounds like you need to flush out the fluid, OP. A power steering cooler upgrade isn't that expensive, may want to look into it if you're thinking about more HPDE's that resemble this last one you went on.

How much tread is left on the Michelins? Sounds like the track may have worn the tires to the point where some of the grip is gone. Even though the car has 6700 miles, the tires may be on their way out.

The power steering fluid is on the Min. line cold and the tires are fairly new, only a few track days on them...plenty of tread left. I'm going the jack the car up tonight to double check all the joints the shocks and swaybar links, etc. and tomorrow I'm going in for an alignment check and fill power steering fluid. I'll report back with my progress! Thank you for all of your help
