still waiting for my day with an ST in phylis!, evenly matched with my old dsg GTi but im sure my car wouldnt struggle now though
if the ST has a remap you may (assuming your not remaped still) struggle IMO, standard you will be pretty even IMO

Thanks for that tt. Will cancel the bids on the rears :smiley:.

Your'e welcome.  :smiley:

Was it on eBay then?  If so, did the ad state they would fit the GTI etc?  If so, the seller needs reporting to eBay.

Dont think the rears would make much difference tbh

They actually would make quite a noticeable difference.  The rears play a considerable part in the stability and dynamics of the car during braking.  Furthermore, the rears also play a massive role during ESP operation.

Whilst the R32/S3 anchors would be a very valid upgrade, IMVHO, the cost, and the fact that you'll need to use "open" CV joints will not only put a big hole in your wallet, you could also be looking at premature rear bearing failure, and an increase in unsprung weight.

The easiest way to "improve" the rear end braking performance would be to regularly strip down the existing brakes, and clean the pad sliding surfaces, lubricating with very high temperature anti-sieze compound such as CopaSlip or Never-Seez.  Ideally this needs doing twice a year - once a year as a minimum.  And no - the stealers do not do this on a service!

If you find that you are "eating" the rear pads, then a common problem on the Mk5 is an over-tight handbrake.  I did a detailed post before on this issue, but the forum "downtime" lost it!  :rolleyes:

If all the above is in order, then some uprated pads would be a benefit.

Car has only done 3k miles so pads should be fine. TT what do you mean by opening CV joints? will i need to do this when fitting the front R32 brakes?
Will probably upgrade the pads front and rear on the car when i have the R fronts. As for with im saving a bit with the team dynamics so should bring the weight back to normal.

Blue 182. There wasnt much in it with the st on the straight, at higher speeds i reeled him in. As for his driving on the corners he was pretty shocking. He would go into the corner too quick and apply the brakes mid corner, upsetting the back end.

Golf gti ed30, tornado red, itg panel filter, revo stg 2, team dynamics gloss black wheels, turbo back milltek, ecs dogbone mount, leon cupra brakes. s3 intercooler ordered.

The R32 rear brakes will NOT fit the Edition 30, nor any other front wheel drive Golf V platform car.

The R32, and the identical spec S3 rear brakes will ONLY fit a four wheel drive car.  The hubs are different, and the wheel bearings are different.

If you really wanted to put the R32/S3 rear brakes on a GTI/Ed30/Leon Cupra R/Octy vRS - then you will need some serious modification to the rear suspension setup, including:
  • two new rear hubs
  • two new rear wheel bearings
  • two outer CV joint "housing" (to support the rear wheel bearing)
  • two new handbrake cables
  • along with the entire rear brake setup (calipers, caliper carriers, discs, backplates, pads)

Boy, there seems to be some mis-information creeping into this forum!  :rolleyes:

blimey thats a lot more work than what the MKIV needed lol

OK.  How old is the car?

And have you checked for correct adjustment of the handbrake cable?  The full detail is found in the appropriate workshop manual as listed in my sticky.

TT what do you mean by opening CV joints? will i need to do this when fitting the front R32 brakes?

LOL - unless your car is a "zero" wheel drive, then upgrading the fronts won't be an issue!  :evil:

Regarding the rears, because the R32 (and S3) have driven rear wheels, the rear end set up is designed to use rear driveshafts.  Now, at the outer end of the driveshaft, this has a CV joint (constant velocity, alowing drive to be transmitted across the joint at a constant speed, irrespective of the angle of the joint).  The "outer" part of the joint passes through the centre of the inner race of the wheel bearing (the outer race is supported in the wheel hub carrier), and is bolted to the actual rotating part of the hub, which also supports the brake disc, and the roadwheel.

Will probably upgrade the pads front and rear on the car when i have the R fronts.

Instead of R32 front brakes, go for the identical spec Leon Cupra R brakes, which are already painted red!

What pads are you considering?

As for with im saving a bit with the team dynamics so should bring the weight back to normal.

What - new rims?  Which ones?  Linky/pics please!  Team Dynamics have a very good customer service, and had an excellent "no-quibble" attitiude with a problem rim I had on SWMBOs previous Astra.

Blue 182. There wasnt much in it with the st on the straight, at higher speeds i reeled him in. As for his driving on the corners he was pretty shocking. He would go into the corner too quick and apply the brakes mid corner, upsetting the back end.

Oh, the joys of muppet drivers!  Actually, these tw@ts make my blood boil, as that kind of driving is invariably lethal to any following motorcyclists.  Slow in, fast out is the correct, and best way of dealing with bends/corners!

I'm not too up with the Mk4 rear end conversions, but yes, on the Mk5 platform, it definately aint a "plug'n'play" simple bolt-on conversion, as many would lead you to believe!  :rolleyes:

There was a guy on here who bought the front and rear R32 conversion. That's why I put yes as my answer. I didn't realise he'd had to change all those parts as well as the brake set :shocked:

MKIV just required some 6mm spacers and the bigger splash guards - rest was plug and play  :smug:

OK, sorry, I didn't mean to have a personal "dig" at anyone in particular.  :smiley:  Just didn't want to see anyone making an expensive "mistake"!  :cry:

Who was it from here who bought the front and rear R32 anchors then?  Have they posted their subsequent difficulties - or are they now the ones on eBay?  :tongue:  :grin:

Ahh - but you see - the Mk5 is a far more technically advanced, superior engineered specimen compared to the meagre Mk4 !!!  :tongue:  :tongue:  :evil:  :evil:
