Hey what happened to the ubb search? I was going to find a long post I made about dsm brake upgrades, but I can't find it....
Like Josh said I also have a big rotor/4 piston caliper brake upgrade. Mine are from a company called TCE, I was one of the test fitters for their first 1G kits.
There are three size options, all being .81" thick:
11.75" fits stock 16s and aftermarket 16s.
12.2" fits some aftermarket 16s and all 17s
13" only for 17s
The kits use a two piece rotor, aluminum hat and iron rotor. That means reduced weight <my 12.2" rotors weigh only ounces more than my stock 10" rotorors> and cheap replacements <$50 each>.
The calipers are a wilwood billet superlite 4 piston caliper. They weigh 3.75lbs EACH, while stock calipers weigh 12lbs EACH <kind of funny, getting much bigger brakes and having it end up much lighter, sometimes you can have your cake and eat it too>. They use a "differential bore piston". What that means is that the trailing pistons are larger and apply more pressure to the end of the pad, this eliminates pad taper, which is a cause of compliance in the brake system <compliance=a spongy pedal feel, basically>. The pads are a universal shape from wilwood. There are many companies that make pads to fit these calipers, so you can find a pad that suits your driving style. Most pads are about $50 for a set <half the cost of pads for dsm calipers>. Since the billet superliter was designed as a racing caliper, pad changes are very easy, takes me 20mins including jacking the car.
I didn't get a chance to do any distance testing vs. stock with acutal measurements, but I did notice a decrease. Pedal feel is AMAZING. Switching from a sliding piston caliper to a fixed piston is incredible. It's so easy to modulate the pedal and really be able to tell right when you are at the limit...which is almost impossible <at least for me> with the stock calipers.
Anyway from what I have seen out there for dsms I think this is the best kit for the price and have been very satisfied. I can't seem to access the dsm ftp site right now, but if you go to pics.dsm.org, then regionals, nwdsm, members, and then nick drake you can see a bunch of pictures of the kits.
Prices range from around $850-$975 depending on options. For pricing you can contact todd cook at, toddandchris1@home.com
