Also in my quest for cheapish r comps for DE, I’ve found that Federal FZ-201s sucks ass. Not worth $600.

Absolutely agree with the assessment. For the price, they are great and like you said, did not get greasy and were pretty consistent throughout the day.
During my morning runs, it was a bit cooler and pushed the car a bit more than I did in the afternoon. They do make an audible sound at the limit and were quite predictable.

Got bored after work and since I'm thinning out the wiring and central locks and the electronic trunk button doesn't work I made this nifty race spec trunk latch quick release

Oooof, I'll be back home by then. Someday!

Tired and hitting the bed after hitting the berms all day. Write up coming tomorrow. Tried some new stuff.

3 weeks ago at Limerock, couldn’t take my E92 because of the noise so the e36 does the job

That's some serious cording...were you trying to use the sidewalls to increase the contact patch?

Lol

I think Arty would still try a few more sessions on those!

That tire was made in Indonesia. I am not sure I would use those as my track tires

[roastbeef]

Two days (~6 hours) of track time out of them at Laguna Seca. Price was right. Not as fast as nt01's though.

But you almost died (or at least hit a wall and/or wrecked a wheel) with that sidewall failure!

[Datka]

I think most would agree that safety should be more important than saving a few bucks on tires.
Again, running those on the street wouldn't worry me as much...

What brand?

[roastbeef]

Achilles endurance slicks. They were new when I got them from a race team that used them for the 24 hours of thunder hill. Can't be that bad...

Had a track day with two issues -

A game of What's This Noise - took me the whole break to fix it.

ok, so i have some things to discuss. the last time i was at laguna was last march, this was also my last track day... got married and had to lay off the track days to save for a bit. that being said, i was a bit rusty. as my confidence and technique came back with seat time, i experienced a few things.

only changes to the car since my last trip were APR spats (essentially gurney flaps in front of the front wheel wells) and three trackspec hood vents.

tires are achilles endurance slicks and this was my second time out with them. they feel good, but not as grippy as nt01's. they don't seem to like a lot of slip angle and start to get pushy when you get rough. i'm probably driving these things wrong, but they were very cheap and i got them new. on my last cool down lap of the day, my front passenger tire's inner sidewall blew. it held together ok for the remaining 1/2 lap until i could get into the garage. no damage to anything.
earlier in the day, i was running them with too low of pressure. they seemed to like 34 up front and 34.5 in the rear so i left them alone at about 11am when it was about as hot as it was going to get. i think the passenger front tire blew from repeated visits to the outside curbing of turn 6. it is significant curbing where i'm dragging that particular tire over. the oem suspension doesn't care for the dip of the inside of 6 and i would get launched to the outside if i went too low. turn 6 just sucks with oem suspension.

a new thing i was trying to be conscious of was turning the steering wheel less. seems weird, but turning the wheel too much when you're trying to turn is a thing. this is especially true at turns 5, 9, and 10. turn 10 yielded the biggest improvement with this technique- i was able to get to full throttle earlier and longer before the braking zone at turn 11. i really enjoyed experimenting with this.

brakes- this was my first time trying endless re20 pads. i was running ds2500's in the rear because the rear set of re20 pads were the wrong size (ugh). i want to say i experienced pad fade for the first time... is that a thing? i haven't had to deal with brake fade since i got my brakes and i would get a longer pedal feel towards the end of a session. i didn't like that at all.
the brakes are the essex ap cp5060/5040 kit. stainless lines everywhere, and SRF fluid. nothing changed since last time but the pads.
SRF was last changed in march when my rear brakes were installed... maybe its possible i got bad fluid? but that wouldn't explain how i didn't get poor pedal feel last time.
i brought my spare raybestos st43 race pads and swapped them in between sessions. they definitely felt better, but i still had a longer pedal press that got a little longer- it just wasn't as bad.

so here is my question- is pad fade a thing? like everything else is good, but the pads are creating the longer pedal feel?
i'm thinking my fluid may have taken a dump at some point, and thats where i think i'll start.

trackspec motorsports hood vents were great. temps never got above the 3/4 mark, and came down pretty quick with a cool down lap. i'm a fan!

dparm a damn c7 grand sport was in my run group. those damn things are fast. we were almost even, but he pulled away on the straights. nice cars.

the car turned 65,000 miles on the drive home. running like a champ.

Almost forgot a few pics.

What did it end up being?
