Jahre Posted July 5, 2013 Report Share Posted July 5, 2013 Last weekend I drove around the Nordschleife for the first time with my Lupo The car drove very well with just a H&R Coilies. What was a really big dissapointment/problem, the brakes. Well this didn't came to me as a surprise but I was little surprised how quickly the brakes were gone After 4 km nothing happened anymore.Well because the idea is to drive more often on the Nordschleife and also other track days, I have been looking for a possible brake upgrades for the Lupo. I know about the G60 upgrade but I'm not 100% sold for this solution. Then I stumbeled upon Porsche/S2 brakes. I know they have been used in mk4/5/6 Golf succesfully but has anyone fitted one to a Lupo? They would require a 305 disc but what I have understood Ibiza Cupra R discs would go. The calibers that would fit would be from the Boxster/986 rear axle. This would be a perfect solution regarding track days, because the available amount of different brake pads would be wast. The price is also not a problem. Other option would be to take S2 brakes. Would these fit directly?http://www.ebay.de/itm/Audi-S2-Bremssattel-Doppelkolben-Bremsanlage-G60-Girling-60-komplett-/171068509495?pt=DE_Autoteile&hash=item27d47a4d37If anyone has some dimensions from the front brake caliber, those would be very usefull.

Deadmetal Posted July 5, 2013 Report Share Posted July 5, 2013 You'd be better off using a decent brake fluid.You more than likely overheated it and that's what cause the lack of brakes. Quote Link to comment Share on other sites More sharing options...
Jahre Posted July 6, 2013 Author Report Share Posted July 6, 2013 I know that much that just changing the brake fluid will not cure my problem Has anyone really tried the G60 conversion on a race track? How long do they last? Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted July 6, 2013 Report Share Posted July 6, 2013 Alan W has Porsche brakes on my old GTI, if he still has it Quote Link to comment Share on other sites More sharing options...
Derv Posted July 6, 2013 Report Share Posted July 6, 2013 An alternative is to learn the track, and brake less. 1 Quote Link to comment Share on other sites More sharing options...
Deadmetal Posted July 6, 2013 Report Share Posted July 6, 2013 You say your problem is brake fade or somting along those lines.Shoving massively over sized calipers on won't fix your problem.You need a good set of disks and pads.The porsche calipers will overbrake the car.

Jahre Posted July 8, 2013 Author Report Share Posted July 8, 2013 Of course balance has to be kept. It doesn't help if the front axle keeps locking every time you brake hard. That is why I'm asking if anyone has tried Porsche brakes on a Lupo. I don't know what would the piston area be in a Boxster rear axle caliper, so can be that there is a huge difference or that there isn't much of a difference.Pads are important and that would also be a good reason to try to fit Porsche brakes, because the selection is so much better. So far I haven't been able to find a decent pads for the Lupo caliper. Green Stuff I don't want to buy. Friend had them and well there wasn't much of a difference to the originals.Now I have bought semi-slicks so the need for good brakes becomes even more important.Defcon5: Do you know from what model was the brakes from?

Inneraxe Posted December 30, 2013 Report Share Posted December 30, 2013 Did you ever go ahead with this Jahre if so how did you get on? Quote Link to comment Share on other sites More sharing options...
Huw Pugh Posted December 31, 2013 Report Share Posted December 31, 2013 You'd be better off with the Ibiza Cupra R set up than running a Porsche rear caliper flipped to the front I reckon. The Porsche rear caliper is only likely to offer the same braking power as a G60 set up. Quote Link to comment Share on other sites More sharing options...
Bigplum Posted December 31, 2013 Report Share Posted December 31, 2013 How do you know that fresh brake fluid will not cure your problem ? It's surprising what a complete flush will do, Are you running silicon fluid ? Quote Link to comment Share on other sites More sharing options...
Jahre Posted January 18, 2014 Author Report Share Posted January 18, 2014 I did found a set of brakes that would have been a bolt-on kit but the seller never answered to me. So I decided to just try out with EBC Yellowstuff, Ferodo FBZ100 Dot5.1 and some braided hoses. Since the change I haven't had a change to go to the ring again but I did went to Hockenheim. In Hockenheim I was able to drive about 10 min hard and then I started to get inconsistant braking. 1 lap cooling and then I was able to go flat-out 1 lap. So the change had brought some benefits but the brakes are still not getting enough cooling.First test I will do is to install cooling ducts and see what that brings. After that new brake pads. The Yellowstuff is good for the street but not really for the track. Well maybe I should ad that if you have semi-slicks and plan to drive hard for a longer period, then you need to consider some better pads.Thanks for the tip regarding the Cupra brakes I will take a look if I can find some on Ebay.
