How did your track day go? Did the HFCs hold up to the heat? Thanks

So far so good, Saturday morning the track was damp in spots due to rain Friday so we were not hard in it in the morning. Saturday afternoon we had 2 - 25 minute sessions on the track back to back, Sunday we had 4 - 25 minute sessions on the track back to back. The only thing that I noticed was last fall ( before the high flow cats )
My track mileage was 7.3, now with the high flow cats my track time mileage is 7.4…:crackup:

Same here! Pretty consistently 5.2 MPG. I’ll bet he had some local miles mixed in with that.

I have not put the car up on the lift yet, that will probably happen this weekend when I put my Z 26 street pads and my Velgen wheels & tires on for the summer

I changed out the brake pads, wheels and tires. Inspected the FabSpeed cats, just a little "Easter Egg" discoloration & some water spots from the rain, other than that No cracks, No issues. Just a snarling, cackling, crackling, just this side of obnoxious, exhaust tone.
Especially if you are lifting off the throttle and just put a little pressure on the pedal....
I love the sound !
