To clarify, I haven't had any "problems yet" since I've just been running with a the stock set up, I'm just trying to plan ahead and prevent a problem from occurring when going to stickier tires, but I do plan on moving the Castrol brake fluid regardless next season.

I'm thinking going to SC3R's might be the best bet afterall and leaving everything else (pads and oil) stock.

Thanks for your feedback

Regarding the track I'm on, the former lead instructor who was a back up F1 car driver said he's been on over 100 circuits in Europe and this track was top 3 difficulty. Sounds like there are some similarities between the tracks we drive on.

Ha! Yea I was surprised how many sessions I got too. I think I could rock the old tires another half day session.

That’s a pretty good idea to run GY 3Rs and stock pads next season. I think you’ll be happy with the tires, run a better lap time not to mention save some maple syrup dollars or whatever you guys use for currency up there

Changing brake fluid made a difference I could feel. Seems less squish and less fade throughout the day. Then again I got about as seat time as you so..

That track sounds sick. Look up YouTube videos that have your car and track. I watched a guy with ZL11LE run a 1:43 at Sonoma. Now I know what’s possible.

You’re welcome hope it helps figure things out.

I wonder how much of an upgrade these are for the ZL1's... I thought i heard the ZL1 has vented calipers/pistons already, but not sure...

Yeah I'm still waffling on this because of price; I'm doing the math and it looks like there is big potential saving going to slicks, like $3000 a year (after the first year when things like the upgraded caliper kit is taken into account) because of the slicks reduced price and increased longevity compared to SC3R's even after factoring in more oil changes due to using 15w50 on the track but not for the street.

I'm not sure how to evaluate the cost of what I assume would be more rotor replacements with a track pad since I don't know how much more wear the track pads will have on cold rotors during street driving and I don't know how much stock rotors cost to replace or if it's worth upgrading them.

But when I hear the Hawk DCT70's don't make noise on the street, that's very enticing. Noise it the one deal breaker for me.

I'll have to see how long my current SC3's will last me so I can better estimate how long the SC3R's will last me, but most members seem to say half as long as the SC3's.
The shoulders on my SC3's have no tread/grooves left in them after 15 sessions, even though the wear bars are only even with the tread on the insides, so if they only last me one more track day (20 sessions in total) and the SC3R's only last half that long, that's 10 sessions which isn't very long. Even if my current tires last 10 more sessions (25 in total) I still think the SC3R's will only last about 12ish sessions or somewhere between 2 and 3 track days which means 3 sets for the 8 to 9 track days I plan on doing from May to Sept/Oct each season. I don't know how you have gotten your SC3R's to last as long as you have, and while I hope you're right that mine could last that long too, I'm just skeptical based on what I've heard so far, but if slicks can last me 4 track days (even if they start to get slower by the 4th day) that would only be 2 sets a season at $600 a set.

Of course this is all speculation at this point with some assumptions mixed in as well and I may be doing to much speculating and assuming right now haha

Anyways, I have a long time to decide, so I'll keep thinking about it and gathering information.

Well I might be rethinking those used slicks now, just got my father's feedback on them and his disappointment with them; he showed me his front drivers side slick and we can already faintly see the cross hatch pattern of the cords on it and this was after only 1 session of driving last track day which means that the slick was more like 75% used up than having 75% life left in it by the time he got it...

It would have ruined his track day had something else not gone wrong on his car and now he's thinking of just going back to new Hoosier R7's so he knows he won't have a track day ruined by a tire with a lot more wear on it than advertised.

You are not going to overheat your brakes. I am considered a "demon" on the brakes and never once had an issue.
Just get some R compounds that are on sale and make sure you have 50% of greater left on your pads and get out there. I am one not to over analyze things but just "do it"
I understand everyone's a little different but just get out there and get seat time! Sorry if I am a little ruff but....

Everyone that I have told to add the SS track deflectors always responds with the 1LE/ZL1/ZLE doesn't need them, it's ready to track from the factory. I don't understand why they want to resist better brake cooling especially for how cheap the deflectors are, but hopefully they will listen to you.

The ZLE already has those, I believe it’s just the SS 1LE that doesn’t.

You sure Sean? I don't have a ZLE, but I've never seen one with them either...

GMG, tire longevity depends on many factors, including the driver. Slicks also mean replacing parts more frequently due to higher loads.

As far as calipers...stockers are just fine as long as you dont go crazy with high torque pads. I can tell ya from first hand experience, that running even top shelf race spec brakes with high torque pads WILL require rebuilds (and per several posts by DTC70 users).

As far as pads...while it is NOT advisable to use high torque pads with street tires (and street calibrated ABS) because of high possibility of lock ups, this is not the case the other way around (as some experienced and fast drivers have attested).

More on pads...different pads, require different braking techniques depending on their torque characteristics. While flat torque pads can be easily modulated by pedal pressure alone, those with rising torque will respond differently to the same pedal pressure, based on temperature. Braking is a very difficult skill to learn (to maintain a well balanced car), yet absolutely crucial to fast laps. Stock pads are driver skill friendly in comparison to some other choices. IMO.

The easiest and least expensive way to try stickier tires would be to simply buy a set of G3Rs in 20s and put them on your current rims when your G3s wear out. ZERO changes required! I believe Sean gets something like 3 days F and 6 days R out them if i recall correctly. Note GM requires track only specific oil for those tires (which some have suggested are on par with R7s - or close to it?).
However, given your home track is of a "driver development" type with relatively low speeds, you may get away with a dual purpose oil. Your call here obviously.

You can figure out your season's budget based on the above info, but: as long as you continue to over drive the car, which you do rather severly at times, including exceeding Stabilitrak limits - you will be wearing out tires faster than necessary (while going slower than their potential).

Cheers!

My ZLE has some sort of black plastic air deflector attached to the control arm, though it appears to be a smaller piece than what is posted in that thread. Perhaps they created a smaller piece that can be left on at all times for 2018.

Agree with TrackClub - when too much yaw and corrections and counter-corrections are clearly visible in the video, you're overdriving. Bad habit for both driver development and tire life. Get more seat time without the overdriving before worrying about whether you're going to catch the P-car in front of you.

Seeing an advanced/instructor group driver trigger the PDR's little Stabilitrak squiggle is one thing. At the newbie level, it's something else entirely, and not a good thing IMHO. Yeah, it's good that you weren't overdriving to the extent that ST couldn't keep up, but at 5-ish track days you should be focusing on learning how to keep the car out of ST intervention. At the very least where even if the ST warning flashes briefly, you should be trying to keep yaw due to the rear sliding below the point where it is clearly visible in your videos, and where you're not making steering corrections all the way into the turn-in phase for a following corner.

To my knowledge, none of the Camaros have the “track” deflectors installed stock. The SS has them in the trunk as optional. To my knowledge, this only applies to the SS (no other Camaro gets them in the trunk)... The ZL1 and ZL1 1LE do have the “track” rotor shields. The SS 1LE and SS come with the full shields (SS has the “track” shields in the trunk).

Cheap cooling upgrade for everyone, that's why I recommend it.

The SS 1LE stock pad compound is by Ferodo and rebranded by Brembo as "HP 1000/1". Word from Ferodo is that HP1000/1="DS Performance".

With that in mind, take a look at the compound graphs by Ferodo and Hawk. Note mu curve of the DS Performance compound, where/how the compound drops off and the drop-off mu. I marked up these Ferodo and Hawk graphs for some insight. This isn't a 100% comparo since it isn't known exactly how Hawk and Ferodo came up with these curves, but it gives an idea on where the OEM SS 1LE pads rank (and how):
