Need Some Post Track-day Advice

aus · 05-19-2014, 06:16 PM

Sorry for the bad pics. There was a blinding glare into the garage.
Saw this leaking down one of my calipers. I was able to tighten the nipple maybe less than 1/4 turn, so it was a little loose, but I've been to Spring Mountain prior to this event, but it was MUCH hotter this time. Is there anything to worry about here?

Here's my front tire that's been FLIPPED already. The wear bars are actually in the middle of the pic. Time for new tires?

Here's the rear tire.

Thanks.
Sorry. Didn't realize the pics would be so big. I don't have a way to resize.

Nothing to worry about. As long as the threads are not stripped and it stopped leaking after you tightened it. Just be sure to check the brake fluid reservoir to ensure it is still full and top it off if needed.

Do you drive over rough curbing? That could vibrate the bleeders loose if you only snug them down.

That could be it, but I was only on the curbing one time pretty hard on that side of the car. Most of the other curbing was pretty smooth.
Thanks.

Anyone have thoughts on the tires? Do they need to go now, or can I maybe get another day out of them. I'm pretty easy on tires generally speaking.

No cords? Good to go!

Drive them until they either cord or the grip falls off.

Whether to use the tires depends on whether you drive to and from the track on them. I'd say drive them to the cords if you trailer your car to the track. If you drive the car to the track, then you probably want to save some rubber so you can make it home ok after the track day. Driving on corded tires at highway speeds is not a good thing.

freeway is relatively slow speed after a track day and the forces placed on the tire are relatively small. that being said i agree, probably not smart to attempt.

Thanks guys. I usually bring the street wheels/tires to the track just in case, so I could always change them out if they cord.

Great to know to run them till they cord!!!

Those are your NT05s right? Yeah, run those suckers till they cord.
