I am thinking of changing my brakes front and rear, you can see a lot if them through my wheels, I have spent days cleaning my wheels with some sort of magic cleaner I found on eBay, now the wheels look show room but the brakes look too standard, what's the biggest disc I can fit without causing myself issues? Can anyone who has upgraded give me some options and also good places to buy from, cheers

One for Raj - he'll know off the top of his head (the nutter).

Brakes: Front calipers plug and play from 4.6is or 4.8is. Discks: drilled Mtec. Pads: TRW. No cheap upgrade for rear available...

When you say bigger discs I assume as in upgrading calipers too to cater for that.

If so you have a few options. As above upgrade to the 4.8is calipers with matching discs. Will be a little bigger but nothing to write home about. This option will give you 356mm discs and then you have options to go with drilled, grooved or both.

You can go the whole hog of course and BBK it like myself. Then you can go with 405mm discs but you will need 20's as a minimum to clear the brakes lol.

Can go 380mm discs with matching 6 pot calipers.

What's you budget and actual requirements?

Thanks raj, I am running 22inch wheels so have plenty room, but the thing I am trying to achieve is a good looking wheel arch area, the standards just look to small behind the rim, I don't really wanna run drilled discs as they eat pads? Budget is about £1000,

Here's some pics of my old BBKs with 22's.

They were only 380mm discs up front.











Also drilled discs won't eat pads. Grooved tend to be more aggressive as they deglaze the pads.

These are the new brakes fitted last year.





8 pot fronts with 405mm floating discs:


6 pot rears with 380mm floating discs:


They really fill the alloys and combination of brakes and rims is spot on for me:







These are gonna be a good buy for a little over your budget of £1k:
