ZL1 Hawk DT70/60 pad question

nlowell · 06-01-2019, 07:33 PM

Hi All,

About to put a new set of Hawk DT70/60 pads on the ZL1 for its maiden weekend at COTA in a couple of weeks. Looking at the front DT70 pads (HB631U.622) I noticed that everything is exact to stock except the pad diameter in the middle. The stock pad seems to curve in to 31.5mm and the Hawk pad stays out at 34mm. I compared a set of PowerStops I had and they were exactly like stock.

Does anyone know if the extra diameter of pad will cause any issues? I understand that one of the companies out there somehow modifies the pads to “fit” and I’m wondering if this is the modification needed.

Anyone with experience running these?

Thanks!
Neal

I’m running the Hawk DT70 F / R

They do not slide in I had to have the center shaved down a touch.

They are amazing pads on the track however they do squeal pretty good on the street. I wish I would have kept my stock pads and done some swapping back and forth.

Thanks Try2Paz! How did you shave the inside edge? Yeah, I expect a good amount of switching back and forth - I’m not a fan of street squeal not to mention I’ve heard these pads aren’t very effective until they’ve come up to temp. Thanks again!

Ran DTC 70/60 combo at CotA a couple of weeks ago. Ordered from www.knsbrakes.com , fit in no issues, worked like a champ all weekend. I also drive them on the street and they've been very well mannered for me.

Thanks RSFR, good to hear! I think KNS does some modification for ZL1 application and I’m trying to figure out what it is since I didn’t order through them.

Thanks! Any chance you have a caliper to measure the width at the center - looks like maybe they trimmed it down some?

They are on the car

What is the part number on the KNS hawk brake box? I’m curious now as I ordered mine directly from hawk.
