You can get duct scoops, hose, etc. at all of the stock car supply places. If you're looking for cheap racing parts, always look for stock car stuff. Try coleman racing, lefthander chassis, pegasus (not stock car, but still a good selection of stuff), etc...

Hahaha.. that works too. :D

Hey Mike... remember when I was talking about using an abrasive pad to clean off rotor deposits?

This from Porterfield:

Nice find! I like this part:

"The best way to avoid uneven pad deposits is proper selection and bed-in of pads. The most common cause of uneven pad deposits and associated vibration is use of street performance pads on the track."

The PFC 01 Compounds (as well as the Hawk HT line) have a very agressive initial bite... not something that's good for us new track drivers as a little tap in a corner may buy you more than you were expecting. :lol:

I think I'm going to go w/ a set of Hawk DTC-70 race pads as recommended by Tim over at StopTech. They're designed w/ a very progressive bite, which should be better for learning to brake at the limit with.

Dean's also recommending the R-4 and possibly the R-4E (Endurance) compounds. They're significantly cheaper than the Hawks, but I don't know their availability for the ST-40 StopTech calipers.

I asked what S&H would be to Reno on each. Will update when I get it.

Damn, I paid the high price :(

Can you get a good price on rotors while as well?

Probably, checking.

Heya guys..thought I would check in since one of your members has come to me with braking issues, and I have a few thoughts.

Not to be rude towards any particular vendor, but Axxis, EBC, and Ferodo have fallen out of grace with the racers I talk to, a few old-school people still use Ferodo, but only if they can find a supply of their older (better) compounds. Axxis and EBC are just mistakes waiting to happen in a race environment. HPDE is a different matter, but you'll eventually either get to that criticla speed (5mph can make all the diff in the world) or you'll try something different and go "Ohhh..thats what you mean..".

:)

Right now -the- hot pad on the market is the Raybestos ST41 and ST43 pads. Relatively low dust (who cares, its a race pad), and the rotor wear is well, not bad at all, once you consder that these carry a solid .7 friction coefficient, or higher. These are a no-excuses, no holds barred high energy pad. On an ABS equipped car I would go ST41 up front, and ST43 in the rear. 41s are too grippy for rear use, and without ABS you would want ST43 in front as well..less likely to stab at the brake and flat spot tires that way.

You can read friction:temperature charts here:

http://www.speedtoys.biz/datasheets/datasheets-all.pdf its 10Mb..proof quality when I go to the printers for shows, apologies for the size, but most of the relevant PF, PFC, Hawk, and Raybestos data is in that packet.

Theyre also way cheaper than the Hawk and PFC choices.

ST41/43 fronts for an STi are: $235
ST-43 for the rear of an STi are: $125

Those are the club prices for those, margins are very thin, as theyre priced to complete strongly already.
