312mm conversion

zekegti · Feb 9, 2005

I am looking to upgrade the brakes on my 1.8t. Can't afford brembos so was looking at TT brakes.

Any opinions on whether it is a worth while conversion and would i see a noticable difference over just upgrading my current discs and pads?

Also what would i need to do the conversion and will they fit behind my 16inch monty 2's

Definately worthwhile. Theyll fit behind your Monty's no problem.

Even using stock discs and pads when i did the upgrade on my GTI there was a massive improvement. I'd fully recommend it, especially to the remapped people, like yourself!

I've read about the upgrade too, but what exactly do I need to get hold of- audi TT callipers and carriers? (What are the carriers? excuse my ignorance!)

Richard W · Feb 10, 2005

zeke - AFAIK it's just the carriers you'll need (and new discs and pads of course!). 17mm bolts hold them onto the hub so make sure you've got the right socket. I think Mike posted the part no's for the discs and pads from GSF recently and the carriers are available from VAGparts or the stealer.

kris - with a 115 you'll need to change the whole hub including calipers etc. The discs on a 115 are 280mm and the caliper carriers (carriers being the bit that holds the caliper in place on the hub and allows it to move as the brakes operate) are cast as part of the hub.

GTis and TDIs 130 upwards have 288mm discs with the same hub as the TT/4mo. By simply changing the carriers the calipers are mounted further away from the hub allowing the use of a larger disc - 312mm in this case. The extra force applied means much greater stopping power even from std TT parts.

yes mate.

How much would the carriers cost? Either new or used.

spencert · Feb 10, 2005

New the carriers are over ?100 each, plus if you buy oem parts from the dealer the 312 mm discs are quite a lot more expensive than the 288 ones.

Richard W · Feb 10, 2005

VAGparts do the carriers for ?58 +VAT each

Anyone got the contacts to do a GB on these?

Andrew · Feb 10, 2005

Yeah a group buy would be good if someone could do it

J4SKX · Feb 10, 2005

I'd be interested in these as well.

Would definately be up for a group buy on this. Being a bit on the young side, do insurance companies penalise for this?

Insurance penalise for nearly everything [

Thanks for explaining that about the different setups on the 115 and 130+ Richard. Is it even possible to replace the hub? Does it cost a bomb?

Richard W · Feb 11, 2005

I've just bought a pair of hubs complete with calipers discs etc from the classifieds on here (Thanks Tom!)

It's a bolt on conversion - driveshaft/ball joint/strut/trackrod end/caliper hose check the alignment and Robert's your mothers brother.... anything over about 60k miles and it'd be worth putting new bearings/hose/ball joint in when you do it.

Keep an eye out on the classifieds here, eBay and breakers - be warned though sometimes the parts from breakers are not entirely straight!
