Aren’t you supposed to NOT be using the abs?
What’s the point of better abs?
On track:ABS is always faster than non abs

The entire premise behind ABS is that you can constantly maximize available grip much faster electronically than mechanically with the driver and pedal

It's humanly impossible to vary pedal pressure fast enough (on/off) to account for the varying grip in brake zones

TLDR: you mash the brakes and let the faster computer sort it out vs having to dedicate mental power and footwork to deal with it. Consistency is key feature with abs

I don’t think you can do better than 9L at that price point. They’re a killer outfit.
That's what's it's shaping up to be. But may have to do custom mounts (AJ hartmann) and have them send me a DIY eco wing (they have a new setup that uses rivnuts vs having them weld it so I can place the wing mount exactly where I want it)

But OEM DSC/Traction is kinda meh anyhow. You’d get a better tuneable option with a standalone.

I can totally appreciate, ABS isn’t one size fits all. It’s a rabbit hole and the install is a pain.
Absolutely, but as discussed, you're deep into standalone DME territory then. I think the stock DME would be mega pissed without the torque request CAN messages from the DSC.

True! Bring this thread back to reality :)

So at the risk of derailing the discussion....

Looking for a single element rear wing to add some stability this season GLTC rules (701 sq-in max wing area, single element , end plates unlimited within reason)

Obviously 9lives is the best bang for the buck. But looking at options for less than 2k if anything exists

Ps aesthetics "do" matter. Really like a wider wing mount (say close to the edges of the trunk)

P s.s also willing to buy wig mounts and wing separate
I like the N9L wing, but it's ugly as fuck due to the mounts.

anyways, buy this.

Hmmm, these aren’t great numbers… The 9L is more effective with less drag.

If running GLTC I’m guessing you’re output > style…
nah you're not wrong, but i also refuse to not run things that are not appealing to me haha.

Zebulon looks great, but that's a huge budget at sub $4200 when fully customized

either of the voltex wings are great too, but 1+ year backorder

then there is my buddy Amir who does these:

True but this isn’t a “what’s best available?” but in response to the OP asking about GLTC sub $2k options.

i have a tendency to read between the lines hahah.

i didn't realize that was the intent.

Edit: I guess this applies to me too. Aesthetics do matter…
Hey, you were right about efficiency, and I’m not wrong about aesthetics (subjectively).

But honestly, nothing could ever convince me to use this thing looking like that, no matter how good it is on paper.

This has been shared a hundred times, but DO88 vs CSF DCT cooler.

DO88 is the larger aluminum one - insane the size difference.

Also made a nice little mesh / rock guard for the air guide.

Because better ABS can stop the car faster than without. For threshold braking you’d go as hard into ABS as possible and the computer will pressure those tires with optimum grip to decelerate the car all while accounting for additional parameters that would be experienced with track conditions, downforce, and slicks.


The task of OEM road ABS is to keep you alive and in control. MS oriented is to stop the car, and assumes you know how to manage the control.
interesting. it isn't something i have much experience with, but just about everything i can recall says to stay out of the abs. so now i'm curious, if you're threshold braking and get into the abs for a second, is the difference between a race abs and oem abs a couple tenths? its kinda splitting hairs, but... i get it.

The intelligence of the system knowing where the grip is and thus being able to maximize decel is the difference. And thus the delta is huge.

Here’s a fantastic old HPA episode with Bosch engineer. It’s long but I think I’ve linked to where the conversation steers to ABS.

I paid that 20+ years ago where I live on my e46 M3 track car! That’s an insanely low price for 2025.

Damn, I pay $3-400 all day down here in SoCal. Depends on the level of work (SPL links and stuff like that add some additional cost), but I've never spent more than $500 getting my car setup.
First time to Harris Hill today. I had received a lot of feedback that the juice may not be worth the squeeze to join the club for reasons like track condition amongst other things. I have to say, to go to a track on a Saturday when it’s 65 degrees out and to have it all to yourself for a full hour is insanely worth it. I came in after about an hour on track cause honestly I thought maybe I wasn’t supposed to be out there 😂. At most I think there was 7 cars on track at the same time, ranging from Miata’s to a Supra GT4 to some guy in a GT3RS that would go out do one lap and come in for whatever reason.

In terms of seat time, man, I’m stoked on the deal. It takes a lot of “track day anxiety” out knowing that at least 19days a month I can go to the track and in 3hrs have put in more seat time than an entire weekend with others. It’s also going to be a great base line for testing - I had just put my new front splitter on and this was the first time out with it and was the perfect environment.

There is a VERY rough bump in one section, but if with my Zeubulon I didn’t scrape. Otherwise - track isn’t that bad - I came from Willow Springs as my home track and that one is 10000x more hammered than this track. It is a tight course, similar to like a streets of Willow or a smaller Buttonwillow, lots of turns, some elevation (super fun uphill running CCW - which I can expect to be very challenging when running CW).

For those in central Texas area that want to go for a weekend, I think I can bring a guest for $200 a day or something like - and again, not at all limited to weekends.

If you can afford it, Setup Wizzard is the way to go for setups and corner balancing. I work at a shop/race team with one and we have different hub adapters for BMWs or Porsche centerlocks/5lugs. Super cool tool. I've been doing setups and setdowns on our clients cars for a year now and it's always a pleasure using it. Toe is calculated with a static function with wheelbase as the variable, hence the generic numbers for toe.
