--- Quote from: DaveB1970 on February 19, 2012, 07:18:06 pm ---The rotors have ZERO float, they are simply bolted, the calipers are two piece so prone to flex, and all this hype about piston sizes is a load of crap , the surface area will work our at around 49-52 sq cm, they might tune the caliper with a smaller small piston for better bite but what's the point when they turn it upside down?
If they're having to turn it upside down to get it to work the piston sizes are WRONG.

Why would reversing the calipers provide no stopping power? Surely outright stopping power would be similar if not identical, but with the small piston deploying first you would maybe have a more progressive setup that doesn't eat pads?
Ref the fixed/bolted rotors vs floating, whats the real world difference between them bearing in mind im not a racing driver. Also do they not use the same bolted discs for the race cars?

Thoughts Dave?

It's horsesh*t, race drivers are on the brakes VERY hard for a very short space of time so they may want the big piston to do all the work in a massive hurry but all that demonstrates is a bad design the right way round..
There is a Move back to 4 pots now in GT2 circles who knows what VWR are doing supplying back to front kits..
Kev at KPM does know his stuff however (I'm sending my customers there) so there might be something to it, I would guess it may be something to do with the overall shortcomings of the design and people asking big questions of it
By rights it's not a technically advanced kit for pure track work, we've got unsupported support for it from people with vested interests but that's it, compared to say an AP competition kit which does work its half price. Don't think that everything that goes onto a prepared track car is the creme de la creme of kit because that's not the case.
Don't know about the bolted/floating race prep....race teams will generally use what they can getaway with, don't forget they can probably do away with inner arches and organise some proper ducting where a road car cant which would help...it's a budget approach to heat management, consider a fully floating setup with proper cooling....you'll run out of petrol before brakes .

the only person using this arrangement on here is Geordie56 on his rocco, I was desperate for you to have a go in it Steve as I think you would be converted, and imvho it's the pinnacle non hyped setup for the Mk5 platform.
if he ever packs in blowing it up, I hope you'll get a go in it
So what's my point?
It's the same price as the VWR kit.......

Interesting Dave, when Shaun has his car back up and running then I will certainly try to give them a go :happy2:

Regal won the VW Cup in their MKV with exactly the same brakes I had on my car. I still maintain that you don't need anything bigger than 343/4pots on a Golf.
Jesus, I'm running 6pots /340s on 1500kgs+ of 135i and that stopped all day at Spa/Ring/Ring F1 track/Rockingham..... I've still got 10mm left on the RS29s too. :laugh:
Get the right kit for the job. :happy2:

^^^^^
What he said, we actually brought the diameter down on the TTRS after doing the maths from 370mm to 362mm that was a big sell believe me....
That said its only a matter of weeks before we see stage 3 TTRS running 600BHP+, I'm happy with the maths on that application.

Vanity sells. The amount of people saying "oh, I'd have them if they were red" when I sold up - clowns.
