Improving your cars brakes: Options and costs - Page 2 - Team-BHP

Viper got what you mean. I guess it does make some sense.

ps: I'll think more on it later am too sleepy right now. i edited my earlier posts as they had some rubbish.

Correct. The metal itself will act like a heat sink. However, the advantage of slotted/drilled rotors is their ability to prevent the build up of excessive heat and gases between the pads and the surface of the rotor while braking.

I could increase the diameter of the discs, but then I would need to get spacers made for the calipers as well.

Slotting is better as you remove less metal from the disc. However, I don't know of anyone here who does this. And yes, brakes are something nobody should mess with unless you are 100% sure of the results.

Actually, I think that is the best bang-for-the-buck solution out there for street use. Simply improving the pads to ones that can withstand great heat while providing better performance should be the first step really.

Ofcourse, going in for pure racing compound pads would be taking a step backwards as everyday street driving will not allow them to reach their ideal operating temperature.

So can someone list out the ideal (in their opinion) pads available in the market today along with the approximate costs.

Definitely. But I'm talking about a more permanent solution without altering the bodywork.

But, since we are talking about this, did you run with such a set up at the track or otherwise? How did you route it and keep it secured?

That would mean new custom discs, na? Again, IMHO you can't get someone to make good ones in India, and if you import them, then you will pay way over you 10k budget.

No, I didn't run with this kind of a setup. My car's bumper is still OE. And to be honest, I didn't feel the lack of braking at MMST.

If you were to fab a custom bumper, then it wouldn't be too hard to route some air towards the wheel wells. But I guess it would be slightly harder with a stock bumper.

well, larger discs yes. But I could look OE too.

I need to take a closer look at the brakes of the RS. Check their size, the calipers, the spindle and see what the differences are. Does anyone know offhand the size of the rotors on the TDi and RS?

v1p3r · 11th May 2007, 19:24

I think your best bet would be an RS transplant. Maybe you should talk to Pete's, I'm sure they have a lot of OE RS kits left over, after they've put their aftermarket big-brake kits on.

Mannn 10 piston calipers? You wanna fly out the window each time you step on the brakes or what?

You better believe it!

Holy moly, they even do a 12 pot job!

Food for thought...

"Drilled rotors are typically only found (and to be used on) race cars. The drilling weakens the rotors and typically results in microfractures to the rotor. On race cars this isn't a problem - the brakes are changed after each race or weekend. But on a road car, this can eventually lead to brake rotor failure - not what you want. I only mention this because of a lot of performance suppliers will supply you with drilled rotors for street cars without mentioning this little fact."

Me thinks cross drilling the rotors would reduce the structural integrity of the rotor. In this case better pads could be a better choice on a street car. Any where we could source these pads from?
Has anyone tried routing a cai to the rotors? I guess the brake dust sheilds will have to be cut. Check this site out they should have an article on it. AutoSpeed - The World's Best High Performance Online Magazine

Wouldn't stuff from the VW parts bin help your case??

RT - Also make sure that the RS rotors can fit within your 15" wheels without any fouling.

As for the rear disc idea I think that's not too advisable without a brake bias controller. Ask Jitu for his opinion, AFAIK he ran a rear disc setup on his car and was facing problems with rear brakes lockup due to a bias issue.

RS disc size is 312x25mm.

Personally I think a set of hotter pads should work wonders for your car. Here are a few options:

AFAIK, Robin already has RS wheels on his car.

Rtech · 13th May 2007, 10:44

Yup, I have RS wheels, so the bigger brakes will not be a problem. Currently checking out some options online vs getting the OE RS brakes here. Knowing Skoda prices, it would probably be more economical to get Brembo's or EBC discs!

elf · 13th May 2007, 11:09

So, Rt, lemme get this straight.

You got RS wheels, RS skirts, RS bumpers, RS badges(?), an RS steering wheel, RS end can, RS headrests, RS boot liner, & a 4 pot diesel under the bonnet. And you now want RS brakes.

What's next? An RS motor?
