To be honest those mods help ALOT. However, they don't count as a substitute for common sense or a decent set of driving skills. A skilled driver without the above mentioned equipment standard may still be able to push a vehicle a fair amount without causing an accident.
It's like saying you're in an Audi RS6, and because of the good suspension, large brakes, 4WD setup you can drive around like a madman and think they are going to save you. If you push your limits and the cars limits when placed in a particular situation you WILL crash.

It's sad, I've heard of many family friends who have witnessed their friends die in the car along with them when they crash when pushing it to stupid limits. The cars weren't clapped out bangers, just the wrong time, wrong place.
Best to stay safe and get the uprated brakes, suspension setup, steering control and just hope you don't end up in a hairy situation.


Just remember Murphys law, anything that can go wrong will go wrong, so best to cover all areas and hope you don't end up in a ditch regretting not getting better brakes and proper tyres. :mad:

Just to point out an obv point here... Keep heat in the brakes???
That's a stupid statement. Road cars brakes ate designed to work best from cold. Unless your talking about red stuff pads this is bullshite.
With road pads ect its when they heat up you get the problems (fade).. I'm not being funny bit you only put m52 in your motor for one reason.. And even if you didn't, you will soongave a heavy foot let me tell you.!
I find with 325 discs and pads I get terrible fade (had this for ages and still no incident and I do drive like a teat) I reckon they would be fine with dot 5.1 fluid. Raise the boiling temp (high performance stuff)
I will be going with this very soon and then green stuff pads later

It's not off topic, we're trying to save your ass.

BTW non vented E30 discs won't last one stop from a ton let alone 150. First thing they tell you is not to use the brakes yes because your non vented discs will melt?
I said:

Can anyone suggest how to test if the boot lights are staying on with the boot shut?

So much rubbish gets spouted on this forum! If you drive fast on the road regardless of brakes/engine/talent you stand more chance of a mishap. FACT.

I have noticed though it is always the folk with no money/budget that want to justify why slinging a bigger engine for as cheap as possible is acceptable. It usually goes hand in hand with:

"It's still a 316 on the logbook, so cheap insurance innit"
How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

Well, this has certainly gone off topic.

I appreciate what you're all saying, but like I said I can price up brakes myself because it's something I'm familiar with. Engine conversions not so much, but we've all got to start somewhere, only about 2 answers relate to my question! I never said I couldn't afford to do any of this, simply asking how much.

I also don't see why my current brake setup would suffer from fade on slip roads with an extra 20kg up front; should I upgrade brakes for when I carry passengers? I also wouldn't need to brake from 100mph or 150, as I don't do now! The braking power wouldn't suddenly deteriorate because there's more power under the bonnet.

My driving style would seriously not change. I'm not a youf who is making his first step up into the realm of powerful cars, I've had quick cars in the past, and TBH I just like sitting at 1500rpm and a manual gearbox - but I don't want anything other than an E30. You may then question the point of even carrying out the conversion, but I enjoy tinkering so much I'd probably like the challenge of doing it more than the result.

I do a lot of motorway and A-road driving and the ability to drop a cog and feed in some torque to get round tractors would be a blessing. If the time comes where I moonlight as a getaway driver, brakes will be my first port of call.

M52 weighs more than 20kg over an M10, nearer 40kg I'd say.
With extra weight, be it passengers, luggage etc, your driving style should change - planning and braking further in advance for example.

I do agree with you that the braking power will not change, but the ability to overcome the braking of the car will change and people won't believe that you fit a more powerful engine to drive the same as before.

For a short time, I drove my S50 conversion with standard E30 brakes (discs all round) and can honestly say around town it was no problem. On the open road though was a different matter - the ability to drop a cog to overtake tractors as you said, suddenly means you will be accelerating faster, to higher speed than before, with more weight and forward momentum. You will need more brake effort to slow or stop in the event of something coming the other way, which happens all to often on country roads.

If the non-vented discs and drum rears were good enough, BMW wouldn't of gone to the time and effort of changing to vented discs on the 320i and discs all round on the 325i. Both have extra weight and more power than the M10.
As standard cars, they all need to stop from 60-70mph, the bigger engined cars have better brakes for a reason.

Take advice from someone who has been there and done that - if you're thinking of increasing power and weight, upgrade the brakes. A change to vented fronts will be a good start.
