Yeah...but I didn't see them for the 6 piston Brembos. I only saw them for the 4 piston.

Ah, then DTC60s are a good choice as you found

Porterfield carries ST43 in 6 piston

For the people that have video with the data inserted like Harry's lap Timer what are you seeing for braking G's?

Last week I was getting up to .9G braking peaks with CTSV and stock pads. Curious what people are seeing with better pads.

I will let you know in 2 weeks after I spend 2 days at Watkins Glen on the new brakes. It won't be as good as it could be because if I brake hard at 100mph the abs will activate. Unfortunately the Nitto NT01 tires I ordered will not be here in time.

I usually get -.9G with the OEM pads, not sure a tack pad will do much better since its limited by the tires.

A quick check of cost for the DTC-60 pads, $300 at JDP for just the front. I paid $180 for the Ferodo pads from amazon, $120 extra for better "feel" seems like a lot to me but to each his own I guess. If I start having issues on the track with the stock pads I will reconsider for sure. Noisy pads are not a big issue for me, it's not a daily driver, but I am trying to keep the costs down so I can afford more track day entry fees.

The more I read the happier I am that I added the brake cooling ducts, I am convinced that is a big reason I am not having issues with overheating.

My guess is less rotating mass. Thoughts?

I never had a problem with the 4 piston Brembos with brake cooling ducts on the GT500. I bring this up to say the swap to 6 piston brakes may not be necessary and obviously there are pros and cons to both.


2014 ZL1

The 4 piston caliper change was because of the IMSA rules for the GS class. Check out the rules for the CTSCC here: http://www.imsa.com/2015-imsa-rules-and-regulations

Specifically regarding calipers:
12-5 – Brake Calipers (GS)
12-5.1
Front: A commercially available aftermarket 2-piece (split into two halves) design, maximum four (4) piston caliper of aluminum alloy, with a
maximum of two (2) pads per caliper is permitted. The caliper and its mounting location must not require modification other than an adapter between
the facing mounting surfaces. A front brake change request must be submitted in writing and approved via written reply from IMSA prior to use in
competition.

That's about the going rate for any track pad.

Stock pads seem to be working for some, it's not a bad pad at all. For me I like to late brake and I don't like that I shove my foot to the floor and get whatever the pads affords me. With race pads the torque is much higher and should allow for less pedal effort, more brake control and modulation with a solid feeling pedal, even if my peak deceleration isn't higher.

I've done the ZL1 upgrade after my brake fiasco at Watkins last year. I'm set to go there again this June. We'll see what happens. Another thing is that right now I have the ZL1 rotors on now...when they're done, I've got a set of Centric blanks to go on. I know they're a bit heavier with non directional vanes, but if they hold up and give me my same lap time, the cost is sooo much cheaper. I can get 4 sets for every 1 two piece set. A lot of the race guys run Centric blanks too because of their cost and they perform well.

Link to these rotors?

A quick search got this source. Not sure if it's the best vendor but the price is very low.

http://www.autobrakecenter.com/front...4-p-27286.html

$99 a piece.

Those are directional...there are even cheaper ones.... part number is 121.62128

[White_SS/RS]

Seems like a viable option. Curious as to how they hold up under track use.
