285mm up to 314mm discs?

[lee gsi]

How easy is it to upgrade from the 285mm discs up to the 314mm set up?

Vauxhall list both sizes for my Signum but I am 99% sure I have the 285mm ones.

Whats needed to go up to the 314mm size?

you will need the calipers and carriers as well as the discs and pads bud

It's an easy upgrade but getting the bits at a decent price is the challenge

Disc's and pad kit on trade club is only £54.37 + Vat so just need to find some callipers then.

I know the discs and pads are cheap as I bought some a couple of years ago, it's the calipers and carriers that'll cost you. I got mine from a saab dealer for 100 quid

If you see any more let me know.

What are they fitted too so I can trawl ebay etc.

The v6 diesels and all v6 petrols from 2004 apart from the vxr (345mm)

Are the 285s standard on the all the non-v6 Vecs?

[John LE]

No 2.0t and early 3.2's had 302mm discs
