Should be worth considering what you will do to your brake balance if you upgrade the front brakes only.

You might need to install a brake bias valve to set it up properly (safely)

Good article at

Wouldnt the standard brake balance take care of that?

Len.... if u REALLY want to beef up yer brakes....

How silly do you want to go and how much do you mind spending...



Check out the Brembo Gran Turismo line....

I think you'll be wanting Brembo part 111.5001A... that includes 313mm discs, 4-pot Brembo calipers, Brembo hoses and pads.... but that's about £1900!

You can source most of them at Top Gear = they were cheapest for the Mk2 / Mk3 4-stud (cabriolet) version (similar spec, but 305mm and 4-stud), but those are <£900.... BUT I needed 17" wheels to be sure they'd fit... 16" wheels were just too much of a gamble and I like my RX2's too much....

Well I did look at Brembo but no way! Not spending that kind of money!
have also looked at Wilwood. Same thing there!

Maybe see if the old Austin Princess twin pot calipers will fit! Get them from a scrappy!  :grin:

Still considering my options really.

I've just bought on the 'bay all this:

Golf GTI 312mm Front Brakes
This auction is for a complete front brake setup.
These brakes are off of my Mk5 Golf GTI. I have only taken them off as i have upgraded.
This setup can be used as a performance enhancement for most other golf model's.
Included:-
1 x pair of 312mm vented disc's
1 x pair of splash gaurds
1 x set of useable pads
1 x pair of carriers
1 x pair of calipers with hoses


I got quite a good deal on it all....  But is it all the right gear and will it fit?

I take it you are fitting these to a MK3.

The offset on the VAG 312mm discs is wrong for the MK3 so you will need to put 6mm spacers or washers between the carriers and the fixing points. You will also need the correct grade bolts that are 6mm longer than standard. Standard is M12 x 1.5 by 35mm long.

If your car has the 288mm brakes you can use your existing calipers and hoses in the new carriers. If not use the new calipers and hoses you have bought.

You will need a minimum of 16inch wheels to fit these brakes under.

Thanks for your reply Paul...

Yes they will be going on a mk3, mine currently has the 280mm brakes as its the early GTi spec.

I currently run 17" Competition rims anyhoo...

Oh, are these the bolts i will need then chap?

They need to be 40mm long and more importantly they need to be at least 10.9

8.8 is not strong enough to hold on brake calipers.
