Brakes on 3.0 vs 2.7

Justin, I see you have 19" rims on yours. If memory serves me right, I think Graeme installed the 2.7 calipers, are they still in place or have you gone back to 3.0Ltr calipers?

I have gone back to the 3.0 brakes, but now have a set of LR 18" that also fit

The entire 2.7 brake package was installed - discs, caliper carriers and calipers. As I did not get the 17" BMW rims with the D4 when I bought it, I decided there was no point keeping the smaller brakes

You'd better keep them locked up now that I know I can make them fit my RR!

I meant to say would not seem a critical amount of metal needing to be removed

Have you noticed much difference in braking capability between the two? I guess you will have needed to push them to make the differences apparent.

Ah, that makes more sense!

I went back as there was no need for the smaller brakes if I didn't have smaller wheels, so we decided to put to original brakes back on, and if I went to 17s later I could always put the 2.7 brakes back on. I have since decided to go with some LR 18" wheels, as they don't require the rear brakes to be changed and the front only needed the smallest amount of polishing to fit.

I have pushed them both, and there has not been a noticeable difference at all going from the 2.7 to the 3.0 brakes, but not with anything in tow.

I'd imagine most people who know about your ingenuity Graeme, would feel very nervous if they found you admiring any particular part of their vehicle as they may well find it transplanted to yours in a jiffy! Watch out indeed Justin!

Now I will have to check the boxes still have the rims in them every time I get home [emoji53]

I used the 3.0 brakes for nearly 45K kms before fitting the 2.7s and apart from the vehicle trying to throw me through the windscreen the first time the 2.7 brakes were used, I never considered the brakes to be different. However I only towed a 1.2T van and only country driving where braking is mostly optional.
