does anyone know good places to get cheap spares such as brake discs and brake pads

You'll get top service from AF (site sponsors): http://www.advancedfactors.co.uk/range-rover-sport-l320-3-c.asp

Also Yeovil and Duckworth LR are sponsors for genuine parts.  Visiting from DISCO3.CO.UK

I've used Advanced Factors a couple of times - speedy service at a decent price. I even got a free Land Rover once (ok, it was an Airfix kit but... ) 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Don't put cheap discs & pads on,,they won't last 2 minutes.

ive been looking around online and ive found a website called paddocks, any good? and also am i allowed to upload screenshots of products from websites other than the sponsors?

As long as it's not your's, you can comment on any company. I would assume this includes to screenshots. Not used Paddock's myself (unless I may have done years ago), but IIRC, some of the cheap stuff is/was carp, so just be careful what you buy.

Seriously though, try Advanced Factors and you won't want to use anyone else.  Visiting from DISCO3.CO.UK
