Titanium brake shims
Anyone interested in some titanium brake shims? I asked TiSpeed to fab some up for the Cobalt SS/TC. I hate having to replace the dust boots due to heat failure. I'm hoping this will stave off some of those problems, and keep the brake fluid cooler too.
I think they normally run about 60 some odd dollars, but they're willing to discount of there's group interest. Any takers?

Titanium brake shims are provided by Brembo, Stoptech, and a few other companies that provide high performance brakes. Titanium alloys have low thermal conductivity ratings, so they're good heat shields. If you go to the track, it's likely that you'll burn off the dust boot to the front calipers. It always happens. Most people just don't realize it. I would like to prevent that. For people with painted calipers, this might help you keep your color for a weekend or two longer before they turn crap brown.
I asked Tispeed about them because they make Ti shims for various applications, just not ours yet. So yes, these are for functional use.

i dont know where this comes from Wangspeed. Shims? If you mean titanium gassing rings, they are not shims but rings with circumferential holes that fit into the caliper piston recess provided for on specific Brembo calipers. The do work. I have used them for many years.
To fit an LNF caliper the pistons would have to be removed machined to accept the rings etc. Otherwise you would not be able to install new brake pads.
I have not seen any burned boots on my Brembos but it happens. The dust boots are not that big a deal, and no one here is racing an LNF so save your money....240 for 4 is what they would be worth installed. If it is 60 for 4 something is wrong here...
oops looks like someone does do shims.....
Titanium Backing Plates
Racers with competition tires and heavy, powerful cars, may experience fluid fade and destruction of dust boots, even after the installation of a big brake kit. In order to control the transfer of heat, some race pads use special materials which act as insulators between the pad friction material and the backing plate.
These titanium inserts, placed between the pad and the caliper, dramatically reduce heat transfer, preventing dust boots from vaporizing and reducing the temperature of the brake fluid. They are especially effective when the pads have worn by 50 percent or more, since worn pads no longer provide as much thermal insulation between the rotor and the caliper.

quote from another forum: "I refer you to an excellent book by my favorite, Carroll Smith, Engineer to Win, pages 189-192. Page 192 in particular will interest you because he specifically tells his drivers to do a cool-down lap after their runs to help keep the braking system from heat-soaking and boiling the fluid in the calipers (which is bad for the fluid) and to allow everything else to cool down a little."
1) Go to fresh new brake fluid with a higher boiling point.
If none is available, then:
2) Improve cooling to your brake CALIPERS, which can be better ducts in the car side, a water spray duct-air-cooling system or possibly even different wheels with more air-space or pumping action....
3) Insulate the calipers from the hot bits in the system better - Page 190 in Smith's book shows a nice little diagram of how to make ceramic / carbon / Bakelite piston insulators that isolate the pad from the caliper pistons.

The Tispeed ones are .5mm for the standard thickness, and 1mm for the double thickness shims. I like how they are held in place by the normal caliper pin. I don't have anything in this for myself, other than passing some info along.
Regarding the dust boots. I agree they're not critical, but without them, you have to check and rebuild your calipers more often. I've had calipers that don't have boots (Alcon B Type), and didn't bother putting the boots on stock type calipers on track cars, because they simply get destroyed. But if you're daily driving, especially through winter, the boots are there for a reason. If the shims help keep the boots in tact, and a few degrees off the caliper, then for me, it's worth it.
If your car never sees the track, save your money. If you go to the track, and you don't need race pads because you're not driving that hard, don't get these. If you're beyond that, you can probably decide if these are worth the money for you.
I'll be happy to report on how my calipers and boots look as this season goes along.

I'll be trying a set out at VIR in a few weeks.
Let me know if you're interested. I have a discount code. They're expensive, but should help hold the heat in the pads and rotors, where it belongs, and not in the caliper.
