I'm not British, so baked beans was not something I had come across until I was 16, specially not for breakfast - my normal breakfast is what you guys call 'continental breakfast'. The first and only time I had a full English breakfast I was sick for two days, and since I have not been able to even smell baked beans.

That's more like it!

This is me when I'm out with friends and the waiter asks if I'm also having English breakfast :rofl:

beans AND toast, a bit flash for a student, toast is enough if you REALLY love your car.....

Prices I was quoted /actual were as follows:

Birds supply Quaife LSD £893.65 +vat

Birds fully fitted £1670 inc VAT you say the 35i series has a welded crownwheel..

I was charged £165+VAT for a specialist to fit in Glasgow with 3 hours labour to remove and replace at B for BMW, labour rate as about £75 per hour.

So about £150 cheaper than Birds doing it..

From what I heard its a pretty specialised job as even the B for BMW guys contract it out.

Out of interest, had to take the car for its MOT and the roads were teh most treacherous I've seen yet here in the Scottish Borders.

A couple of hills, one with a very sharp, steep turn.

Both the zed scampered up on summer tyres with only a very little flash on the DSC on the first steep hill where quite often, non AWD cars just get stuck with one wheek spinning..I was taking it very very carefully but anyway..there you go!

I could not imagine Z4 ownership without my Quaife diff. It was my very first mod and especially with a tune, it’s a must have.

Also, an RWD car should really be able to light the rears up without any one tire fire. Disappointed they didn’t have it as a factory option.

I can highly recommend it if you are anywhere above 300 hp or like to kick the back end out every now and then.
