Thank you very much for explaining and doing this!

Will be one of my modes after wheels & suspension...

Send me a PM if you have any questions

Teej-h · 10-11-2021, 10:22 PM

I sent you one earlier, I think because I am new to the site it may not have came through.

How can I get ahold of you. lol. I was going to by the kit from Tronik but would much rather support a forum member.

Looks cool. But with it being custom pad we have a sole source for pads?

Like I said earlier in the comments, the pads are now available online with Porterfield brakes, I have the part number for it with them and you can get them through their website from now on…
I really wanted to make it easy for myself and everyone.. this is very custom setup but the pads being available so easily make it perfect for longevity…

What's the lead time on ordering a kit from you in blue to match stock fronts?

about two weeks, when you order pads online the lead time for those is about a 5-7 business days.

Spitballing here, thinking of doing this but want to go with red. Are you sending out to powder? If so would it be possible to send you my fronts to do at the same time? Or what's your price for un finished set? Thanks! Getting close to deciding here

Although easiest for me would be just sending you an not powder coated caliper so you can get it done yourself with the same color on both..

I would be down for that option. Thanks

Ok, just got the word from Porterfield and they updated the pad design online and everything is good to go!

I made the pad thicker so each pad is 16.5mm thick..
Design is as follows:

Cbozz · 10-14-2021, 11:45 AM

To compare the oem pad to this one I measured it and the actual friction area of a half way used oem pad… seems like my pad is about twice the size of the oem.
Oem pad friction area gets bigger as pad gets used up, my pad stays consistently same size.
here are the pics:

SaNGRia · 10-14-2021, 08:07 PM

This is for people who re wondering about the color match of the OEM Calipers. Be honest the one i am retrofitting is way better painted than OEM

Only thing i want to mention here is, the unpainted areas has some sort of tape glue, u just need to clean them before install the pads. Yours might not have it, but just in case check before the installation.

Akkord29 · 10-15-2021, 12:38 PM

The color match is perfect. If I didn't already have the tronik setup I would be all over these.

Keep in mind that the Tronik calipers are also Brembo, so whatever you decide your getting a great caliper to start with.

How's the brake dust off these?
