So after a going around VIR and having some spirited backroad drives, I have some things I want to address:

Here’s what confuses me, when I drive hard the brakes start to vibrate as if they’re warped. BUT, once they have cooled down, they give off no vibration which leads me to think warped rotors is not the issue. Any thoughts?

Next, after hard driving, I heard the following noise from the coolant cap/tank area. I just topped off the fluid with another quart or so before this, and have already replaced the self-bleeding cap. Any thoughts on this/how worried should I be?

Next, at parking lot speeds, I hear a grinding when turning the steering wheel left. I have been advised that it’s probably wheel bearings but I didn’t feel much play in any wheels so I’m wondering if it could be anything else or if it’s just not bad enough to feel play yet?

Lastly, the shifter has a stupid amount of play partly from factory and partly from worn down bushings. I’m thinking I’ll do a short shift kit to fix this but just curious on opinions. I can either go $500 Porsche route, $300 B&M, or $60 eBay. Curious how dumb I would be to go with the cheap eBay shifter considering it’s only $60 and I don’t see what could be so different about these mechanisms.
