Movit v Porsche brakes

[johneroberts]

Ahh, brakes,brakes...everyone seems to have troubles with brakes...even CSL owners complain about their brakes...

Nothing wrong with my brakes matey

On actual braking performance, I was mighty surprised at LeMans last year, when Marc Duez showed what the standard braking system is capable of (after turning off ESP) at the end of the long straight !! - Outbraking all sorts of machinery - but then he only did two laps in the car and I think he'd have been in the gravel trying that after a couple more laps.

Didnt realise Marc was at Lemans, i could have sworn he was at Spa?

Ok, ok smarty pants!...Spa!

There's nothing wrong with your brakes cos you don't go fast enough to have to slow down for corners!

a great many German CSL drivers have switched to Mov'it brakes, the stock ones don't stand up to enthusiastic use.

Best ask phil and Gav a bout that mate, better still you will see for yourself soon......
You thrill seeker you...go and throw yourself out of another plane

Looking forward to that passenger ride matey!...although I'm not sure if I should be...it might start the 'maybe I should change my car' thoughts off..

Actually never been in a Porsche of any kind...keep thinking about taking one on a test drive..

I'm fitting on my RS4, the RS6 8 pot caliper and the brembo disc 380 x 32 mm with ergal support designed by MTM .
I've reed the discussion and I've see that sameone wuold buy the Big brake systems by AP .
Ok, but you mast consider that AP Company wos buight , same years ago by Brembo S.p.A. . The disc and the pipe and the pad are the same of brembo brake.
Also tha RS6 caliper is made by brembo.

Didn't realise you had a CSl jr, could have sworn it was GT3

I think how you use/abuse the brakes also has a massive effect on braking performance....late and hard seems to be the way to do it if you want to preserve good braking performance (which seemed a bit crazy to me when I first heard it).

Theory behind it Dave is that the less time you are on the brakes the less heat and wear you will generate even though they being used more aggressively (short sharp stab as appose to a long drawn-out grind), also the harder braking will shift the wieght over the front wheels more allowing you to turn in much later/harder and then get back on the power earlier. All fine and dandy until it goes pair shape and you leave the braking just that little too late. Suppose it dont matter though if you ain't paying the bills.

[DaveP]

Yeah...when you think about it it does make sense...it's just initially you tend to think that if you brake gently they'll last longer.

Like you said bud, it's all good until that point at the end of the straight when you slam on the anchors and find there's a bit less stopping power than you thought there would be (for whatever reason!) - kitty litter time at the least if you're lucky

Main reason I brought that point up is that from what I've read some CSL owners have had problems with standard brakes, others (with just a pad change) get on okay with them on the track....seems that how they were braking was making all the difference.

On the CSL/brakes thing

We ran a tweaked E46 M3 at the ring this year and as the cars Movits were'nt ready in time, I fitted a set of pagid yellows(RS29) to the front and bled the system with race fluid,just removed the pads yesterday after 4 days at the ring and obviously the journey home, pads down to 1mm, discs well cracked and due for the bin, so while you can get away with a better compound pad,OE discs and fluid, if you're pushing on(our man was) the cost of constantly replacing discs and pads rapidly starts to make the big brake kits more attractive.
The same driver in an MTM S3 with Movits last year, 3 days at the ring, pagid orange pads about 1/3 worn, discs fine.

[DaveP]

Ahh...interesting Tom...by the way, have you got any pics of the mesh you've done in the front wheel arches to allow for more cooling to your Movits matey ?

I attacked mine last weekend with a Dremel in order to try and improve things...I haven't opened them up completely, as I thought the downward slant of the plastic may actually help to move the airflow around a bit more in the wheelarch. (could all be boll0x, but it seemed to make sense when I was looking at it!)

I think a dedicated piece of flexible tubing running from the front intake grills right to the wheelarch would be the way to go, but haven't been brave enough to remove the wheelarch liner to have a proper look and see if there's space yet...

[TarmacTerrorist]

Dave, let me get the prices for the Pheaton cooling ducts, just been a little busy this week thats all, they will do a better job as they force air directly into the back of the wheel itself (exactly where you want it).

[PhilT]

I'd be interested too Gav.

[SimonS4MTM]

And me, i guess they would fit an S4 just as easily

[Jani]

Looking at Etka, it would appear you need the following:
3D0 615 447B -cooling duct left
3D0 615 448B -cooling duct right

You may also need the splash plate of the discs, not sure whether the RS4 splash shield fits with the duct.
3D0 615 311C splash shield left
3D0 615 312C splash shield right

As always, no guarantees the parts numbers are correct, or that they fit. Shouldn't cost too much if someone wants to make a prototype.

The brake discs of Phaeton are only 345 mm, but maybe the cooling ducts can be modified to fit. Besides, the air intake is from the middle, so the difference in size shouldn't matter too much.
