The ti shims are so thin it shouldn't be "jamming" against anything. I still have my old ti shims I use on the rears.

I'm sure none of you on here have even heard of these pads, But I've have great luck with them so far, they are made by Power Stop and are called "track day" pads.
They have an HH friction code if that means anything to you, they are a carbon fiber/metallic blend.

On my last event I ran these pads in the front only and I managed to get them Red hot and they held up great, the stop tech pads in the rear however i managed to glaze those. I am now running them front and rear (mated to centric high carbons) and have my next HPDE a week from today.

The best part is the price, total for front and rear was about $170 from rockauto.com
they don't list them under the evo drop menu, you have to search the part number on the website, the fronts are PST1001 and rear is PST961. Ohh and they are dead quiet, I daily them as well.

Does anyone know if AMS ducts work on Evo X brakes? Is the center section of EvoX rotors the same size as the Evo8/9?

posting this here as it's more relevant:

on my current setup i'm using titanium shims to work as a heat shield - but in theory, this should keep the heat away from the pistons/calipers but keep more on the pads & rotors. given my vented pistons, should i not use the shims, let the heat come through more and let the pistons vent it.. or is it still better to use the ti shims?

I would keep the Ti shims on. Plenty of other area's for the heat to go to.

what do you mean, specifically? i guess i'm not sold on ti shims (even though i've bought them) - the heat is stopped from going to the piston, but heat generated by braking is not decreased. so the pad will be hotter, the rotor will be hotter. The caliper will ? The theory is that the caliper will be cooler, right? And thus prevents fluid from boiling?

You want to keep as much heat as possible away from the piston and fluid. Thus you run the Ti shim.


Honestly, at your power level and use of the car, you're way over thinking your brakes.

well i've boiled twice, but on the misfitted ti shims. i haven't been out to an hpde again since getting the vented pistons, correct ti shims, etc. gotta figure it'll work better than the previous setup though

You boiled the fluid on pads not cut out for track duty. IIRC you bought some actual track pads. They make a world of difference.

Sam overthinking something...I dont believe my eyes

Whats pads are in there now? And a lot of that also had to do with the Ti shims not fitting properly and fully retracting thus dragging and causing excess heat IIRC

What needs to be done to keep the Ti shims from causing dragging? I think I may have this issue as well.

kyoo

iTrader: (29)

what ti shims do you have?

my shims dragging was a theory, i'm not sure if i can prove that that was what happened, outside of fluid boiling way too fast

I have the ones from hardbrakes.com

Kyoo's were dragging because the shim wasn't notched to clear a rivet on the pad backing plate.

^ that. sorry for the non response.
