<p>Rumor is the flexy dynalites can cause pad taper too though.</p>

Forget helicoil. When threading into aluminum you want to increase the area that you are distributing the force over. The helicoils do not greatly increase the hole size. Using something like a threadcert where you drill and tap a 1/2-13 hole for a 3/8-16 threadcert allows you to get much more better strength out of the bolted connection. I did a lot of testing on this and found that if you have at least 10mm thick alu you can get the 3/8-16 fasteners to work very well with 30 ft/lb recommended torque. They will strip at >50 ft/lb so there is little margin for heman torqing.


I have sold my last two sets with no inserts and no complaints. Just make sure you use torque wrench. I have installed and removed my set close to 10 times with no issues.

They do still taper -- but it is MUCH less than the OEM caliper and allows you to get a lot more life out of the pad.

We need some input from the track rats around here to see if this is a real issue. I have not heard about it, at least not being a big issue.

I can confirm that they do taper from front to back, and you can avoid some of this by swapping the pads direction after each track day but they still wear unevenly in my experience.

These are the kind of inserts I am talking about.

<p>I'm still feeling annoyed that I didn't see the V8R Dynapro kit that doesn't require spacers before I ordered my Dynalight spacers-required kit from 949 for $40 more....</p><p>&nbsp;</p><p></p>

I'd still like to know what's different about their hat that make them clear.

Laguna is brutal on brakes. These are Wilwood "B" compound pads on the same Goodwin dynalite kit as what pulled out the helicoils. I'm using DTC-60 and a TSE 11.75s now, but I haven't run it at Laguna with that setup yet.

<p>Don't they just put the caliper farther inboard of the hub? doesn't seem that hard to do with a custom hat.</p><p>Hey sean, thanks for stopping by, hearing from people like you is really helpful for us less track experienced people.</p><p>Do we need another thread title change?</p>

How much taper are you seeing >1/16" front to rear? I would only be concerned if you are getting so much taper that you have to trash a pad that still has a ton of material left on it.


Edit. Sorry posted before I saw the pic. That is more taper than I would expect.

I get similar taper with Carbotech XP-10s on an old-school 11" BBK with Dynalites. The XP-10s have a wear slot, and I change out the pads when the slot is gone.

I need to try Sean's idea of rotating pads to extend life. Easy enough to do when rotating the tires.

<p>@Lincoln Logs, so switching to dynapros *completely* alleviated the taper issue? Or just made it less shitty?</p>

Dynapro pads are a little more expensive. Quick search showed about $20 more for a set of DTC-60 pads compared to Dynalite pads. The pads appear to have the same area so it is not like you get more pad volume or area for increased pad life.


I also read that you see much less pad taper with more aggressive/higher coefficient of friction pads since you are applying less pressure and deforming the caliper more when using a pad with low coefficient of friction. Makes sense. Proper ducting and cooling will reduce taper as well.


I would like to see how much pad taper is seen with DTC-60 pads that most people seem to use.

<p>You missed the bit where Dynalite pads fit in dynapro calipers . I thought they also might have been thicker</p>

The pad taper in the Dynalite is caused by the inherit flex of the caliper, moving to the stiffer Dynapro will help alleviate this issue as well as improve pedal feel. We still have some testing to do at tracks, like Laguna Seca, but current results are indicating much improved wear. Once we finish our testing we will post our final word on this subject. Keep in mind the Dynapro solves more issues than pad taper, as the Dynalite heats up the flex gets worse making for a more squishy pedal...the Dynapros improved design resists this more.

SOME Dynalite pads fit in Dynapro calipers

Only some do, as explained in your link; the ones by PFC and whoever else that have the 3 holes for either caliper.
