Re: what brakes do you use for track use?

Most OEM brake lines are Kevlar Type 29 reinforced with a PVC casing. They're as good as anybody needs, provided the casing is in good condition. If they get very old and cracked, the Kevlar can quickly degrade too (when exposed), whole line is knackered and needs replacing. Some people argue armour...

Re: Lose power and car slows down only when driving in the rain

Which brakes do you have, Big Blue Brembos or standard?

If they're standard, dirty/corroded slider pins are most likely, imo.

Re: Lose power and car slows down only when driving in the rain

All modern BMW's should attempt to automatically dry the brake discs (by just gently applying/wiping the brakes in the rain) when the wipers are on, definitely shouldn't effect the speed though. Sounds like yours are over-active, or more likely, you have a binding brake caliper which isn't releasing...

Re: M235i 19’s

Depends on wheel width, if you want to go super wide J you'll need big offsets, yes.

8.5" at ET45 will rub on the front struts though, ET42 is about the max.

That should be the start date, dipping & painting is one of the first processes: https://www.youtube.com/watch?v=zn1ulEKkOWU

Going to be pokey.

Fronts would poke out 23mm more than standard.
Rears would poke an extra 31mm!

Re: M140i what oil and what for track

I'd go 0w30 just incase the temps rise.

0w20 is for fuel economy.

Re: M140i SE BUILD DATE

Slightly off topic :) Where on the car can I find information about production date? It's not on tyre pressure sticker on door frame. Last 7 digits of your VIN please? I know about the realoem if you're thinking about that. Thing is, it is a different date that in vehicle papers (vehicle certificat...

Re: M235i active sound

sounds mad, but I'd try OFF (in the hope that means standard) and 'rather loud'.

The S55 file is known to be very quiet. Weird that you don't have the N55, B58, N47, N20, etc, options too?

Re: £40K tax

The P11D value is the list price of a car including VAT and any delivery charges, but it does not include the first registration fee or road tax.

Re: Wheels & Tyres FAQ- please read before posting

Does anyone know if the width size of an alloy can have an impact on the wheel bearing? My car has come back with an advisory for the front wheel bearing on its MOT, its running 8.5J aftermarket all round on my 2012 1 series. Its under warranty and this is covered, but wondering if BMW will kick up...

Re: Few issues pls help

What are you washing the car with? Some shampoos can leave squeaky deposits, believe it or not! I'd try cleaning the door rubbers very thoroughly with some household APC and hot water. One shampoo which seems to quieten down the cracks and noises is Autoglym Bodywork Shampoo and Conditioner, could b...
