upgrade rear brakes?

[aerodynamic18]

i have noticed that some of the guys have been talkin in the 314mm thread about changin the rear brakes for larger ones and that all is needed is new bigger pads new bigger disks and different hub carriers but using the same rear brake calipers. is this correct and has anyone done it yet?

I don't know about using the same callipers but bigger discs are really only a cosmetic upgrade as 90% of the braking is done by the front brakes - I doubt anyone would see any improvement in braking efficiency by fitting larger discs on the back

Apparently it is correct, You only need the cailper carriers and new discs, I guess that as the sizes are not that different, the standard rears on mine are 278mm (or 279mm?? ) and the bigger rear discs are 292mm.. The calipe carriers are around £34 ea from LMF.. I'll be doing mine shortly, just need to make my mind up what disc's im going to order for front and rear..

As Ian said, its only cosmetic on the rears, my new wheels make the rear discs look small, hence why im changing them..

Hmmm. Just ordered some Vx replacement rear discs for my GSi. I've asked for them to be grooved for an extra £35, the total bill for the Vx pads & grooved diiscs is £130 delivered.

How much more would the discs be if I ask them to upgrade me to 292mm + the caliper brackets?

[muffking]

Just seen that you say the brackets are £34 each... That's another £68 + the extra cost of the discs & weight in postage

You already have 292 rear brakes if it's a GSi !!!!!!

its depends on what year the car is according to vx! my gsi was made in 03 and has the smaller i think 273mm i think he said! i wanted to upgrade the fronts and rears but the mounting brackets needed were £80 a pair

VX are talking twoddle matey my Elite is a late 02 and that has 292 mm rear brakes the only difference was on early 3.2 engined cars the fronts were 302 then changed to 314 no difference to rear brakes has been made

cheers mate mine need changing the end of the month will check the size before i order them! wanted to do the upgrade to the front but cant justify paying £80 for brackets so they will fit!!

A quick test if your rear discs are vented then they are 292 mm if they are solid then they are 278mm !!!!!
