I didn't make any extra modifications regarding cooling. I believe though that Dave, Gav and some of the other RS4 guys are getting hold of some ducting designed for the Phaeton. Its discussed in depth on the Porsche vs. Movit Brakes thread on the RS4 forum. Dave has recently put up a picture of the part in question. I shall see if this improves matters for them before taking the plunge myself.

When I said we took extra care all I meant was we did our cool down lap after a 15 minute session and then drove carefully up and down the runway at Croft for a further few minutes to dissipate as much heat as possible from the discs before parking up again. Basically, if they were still 'ticking' as it were, we drove until they'd stopped. None of us suffered warping or fading on the track. Obviously had we been lapping the Nordschleife, as some of them did recently, this may not have been possible/sufficient and they may have done something else, I'm not sure.

When Keith says the inadequacies are in the caliper he's made it clear he's talking about stopping power, not cooling. He's made me as aware as I can be, with my limited mechanical knowledge, of the problems surrounding the heat transference between rotor and bell housing and the pins and stuff. I agree that if my funds were limitless and I tracked the car more than the 3 times a year I do now, in short 15 minutes bursts, then I would want to address these issues too. I don't think its fair to refer to him as some guy in a shed. He knows me(my budget), my car and what I intend to use it for. He fitted Movits to my S3 and they were excellent. So far my experience of this option has been excellent too. The ABS, ESP etc all function as before and my stopping power has improved significantly, which was what I set out to achieve. They were a very good price relative to other options and they look and do the business IMHO. :D

Nord,

Careful there mate, I'd hardly call Keith a little man in a shed. Dialynx is a very well respected tuning house that have produced some amazing Audi's. Keith is a also a pretty good driver, his 1.8 quattro racer is a really nice and well sorted car.

I don't believe Keith is trying to produce a killer setup to compete with Movit kits, he is trying to produce a reasonably priced alternative to Movit/Stoptech kits and should be applauded for this. How many people even try this in the Audi world? IMO he doesn't deserve to be slagged off and disrespected or accused of not knowing what he is doing.

If you want to know about his setup give him a call he is a very straight forward and helpful guy. I have no vested interest in defending him other than he has done work on my car, which I'm pleased with.

You've heard people on here tell you the setup is able to cope with track work and road work very well, it costs about half the price of the Movit kit. For those who can't afford to spend a few thousand on a full blown Movit setup this seems a good upgrade path.

Totally agree, KayGee. If I could have afforded them I would have gone for Movits as I did on my previous car. What Keith offered me were all the alternatives with the implications fully explained. Rather like custom remapping, which is a vogue topic at the moment, Keith will get to know you and not simply slap on any old set up be it brakes, suspension or performance enhancement becomes it comes out of a box and is easy for him. Many times in the past he has talked me out of spending money because he's felt it wasn't justified in my circumstances.

I will admit that I consider him to be a good friend so people can take what I say with a pinch of salt but I have no vested interest in Dialynx as a company. The set up I have was an experiment designed precisely for people like me. Its an alternative which I feel betters the original Audi one. I'm simply sharing my opinion which is what this forum is all about.

I looked at this route myself a long time ago when I first had the car. Unfortunately at the time I didn't have the caliper to let my engineer take a look at it for the fitment. It would appear though that not a lot was required in the end :cool:. I bought a set of movits at a reasonable price so I never followed it up.

Yes, as a cost option alternative I whole heartedly appauled Keith for his effort. As I see it, this mod will definately give improvement over the standard kit in a few areas. I would imagine that the feel at the pedal is much better than the standard caliper under normal road driving conditions due to the fact you have 12 pistons being operated over a larger suface area under your foot. I would also say there is a good improvemnet in stopping power when travelling at speed aswell, I found the standard callipers very poor at speeds above 120 when wanting to brake hard, especially with cold brakes. It was almost like the pads were vibrating against the disc at that speed (gasses evacuating perhaps, im not sure). I would think this kit would eliminate that tendancy being able to clamp the pad to the disc in a better fashion.

Only thing I would question is the use of the Yellow Pagid pad, bit heavy wear for general driving imho although will give the best bite at the disc. Easily changed I suppose now having a mono block design :thumbs:

Is he offering this kit with the quattro gmbh disc as an option also? If not something you could upgrade to yourself at minimal cost when the standard disc wears out.

Baker,

The ducting is only £20 mate, I would just go buy some and fit it!!

Looking at the piccy Dave posted they attcah to the splash sheilds, I dont have any on mine anymore, you will probably still have them on. Looks like I may have to go buy some and then cut them down to allow me to fix them to my car. hey ho

Cheers Gav, you're absolutely right about the brakes feel at speed. They are much more secure. Previously the car had a real tendency to wobble about when braking hard from anything above about 90. Could feel quite unnerving. :shock:

You're right again about the yelows. My reasoning was Audi put brand new disks on prior to me buying it in January. Didn't seem cost effective to take them straight off and replace so I went with the yellows to begin with to make sure I would get the track performance I wanted this year. Its not my daily drive like yours so I thought I'd experiment for a bit as per previous post. Keith has another set of softer pads ready for me in case I want to swap them round for everyday stuff and use the yellows just for trackdays. :mrgreen:

When the disks are shot I'm planning to upgrade anyway but I figured I might as well get some wear out of a set that cost me nothing. Thanks for the advice about the ducting. Has Dave fitted his yet?

Cheers
Deane

This is not the not the first time someone has used the rs4 discs with a different caliper with some success, Mr S2driver has been running around on rs4 discs and AP calipers for ages -

Sure there will have been numerous conversions on other vag cars aswell that we have never heard about.

Don't forget he lives in Germany. To the Germans, all our UK engineering companies are to be looked down on. Trouble is the situation with MG Rover didn't help our image...
