Anyone know the differences (other than £50)? Also do know if they come with everything in one box or would I need to buy something else?

the come with different calipers

I think the midilite kit is the one you need for road use. The midilite calipers are fully dust sealed and have an anti-squeal system to stop the pads from, umm well I guess squealing

I think you also need to buy the pads and brake lines.

Turbo-Brown has this kit on his E30, so he should be able to tell you whats needed.

[Turbo-Brown]

I'd go for the radial mount kit as it's easier to fit bigger discs to if you want at a later date.

There's a bit of plumbing involved to get the calipers mated up to the flexy lines on the car but only a couple of hours work at most.

Other than that, you need to either remove of modify the dust shield on the suspension strut and you do need pads as jmc330i says.

Mine do squeal though so be warned!

Thanks for the info What is the difference between the radial/lug type? I assume its the way the calipers are mounted to the car?

[Turbo-Brown]

I'm probably gonna do an appauling job of explaining this, but lug mount calipers attach in a similar manner to the standard calipers with the two big bolts being parallel to the axis of the hub, whereas radial mount calipers have their mounting bolts perpendicular to the hub axis.

This means that if you want bigger discs, you can make up some spacers and fit longer bolts to move the calipers out.

Ah-ha!

Here's a lug mounted caliper:


and here's a radial:
