big brakes
I, like many builders have fitted the dual servo kit that Mike supplied, and a tremendous asset it has proved to be. I have went a little further in terms of breaking this week . with the addition of bigger brakes and discs. I have my sportster as an E30 kit, which has 265mm brake discs. but I have and e36 m50 engine in it, with a few modified extra horses! I came across this site on the web https://sites.google.com/site/e30brakesolutions/home
I thought this looked like a good budget way to attempt this and so the adaptor mounting brackets with bolts, and brake hoses adaptors, flew there way across the atlantic for about £50-£60. I purchased the RX7 Fc 4 pots on ebay for £70, and rebuild seal kit for £20, and grooved/drilled discs for £70 [MTEC ebay], and my local engineers took 1mm off the centre bore for £20. It took about 1 hour to do both sides. Alas I tried to upload the pics, but after got a message to say a security token was needed,,,any ideas?? I have edited this as I hope some fotos from flickr are able to be seen at https://www.flickr.com/photos/78885582@N04/?

That looks like a really neat, and cost effective, brake upgrade: a real bargain compared to the big brake kits on offer.
Have you driven it to know what kind of difference it makes?
Will you need to change the master cylinder to accommodate the extra volume of the 4 pots?

Brakes
Hi mike, I haven't bled them yet to try them out. I have planned in improving the front mudguard stability, and as it's been a while since I worked on the car, I want to recheck the servo striker pin integrity into the master cylinder, and reckeck the angle the servo rod meets my brake pedal. I hope the master cylinder will suffice - it is the Sierra type. I know some if the mathematicians on the forum may shed light on this- I can only judge by a test drive. Hopefully nearing completion, but I know this car has been modified more than Katie price/Jordan along the way(hopefully for the better) !!!!!!

Don't forget to fit a reasonable brake pedal return spring as well, otherwise you may end up with sticking brakes.
The one for a landrover is fine, and only cost £2.19 on ebay.
Good luck with IVA - let us know when you get a date set.
Babies - eh? Did you ever think they could take up so much of your time??!!

How much further 'above' the disc do the new callipers sit, Jeremy? I've seen this as an option on the e30 forums, and wondered if they'd still fit under 'normal' BMW wheels... and hence my new wheels.

Big brakes
Goo, I just saw ur question, so I will measure and post a picture in Flickr.i have since found a slight problem,- it wound seem the offset of the disc on the hub is different, and brings the disc very cl0se to the lower ball joint for the steering rack- will it pass IVA and cud the seal melt?cud an e30 builder post a comparitve picture? Thanks
