Hello all.
I bought my car back in August 2012. Have been on here ever since but all my questions and updates etc have been scattered throughout the board. I figured I will make just the one thread to update and ask questions. Hopefully even give a few bits of advice, though I'm not a guru yet.

Little bit of a backstory. I use to have an E32 740iL as my daily driver and a Ford Cortina that sat in my garage for weekend use. The E32 was getting a bit tired and I wanted a quick reliable daily driver. I was looking at something along the lines of a C32 AMG as the E39 M5 was a bit out of my budget.. I was looking on carsales at work one day showing a work mate.. Really just having a browse when I stumbled on a very clean E39 M5 for literally half the price of anything else at the time. My immediate reaction was
"WTF I'm going to buy that"
I did a check on the car and found it that it has been involved in a collision back in 2007. I gave the guy a call regardless and left a deposit as it was too good a price. Even if the engine was blown and it needed some exterior work I still would not have been out of pocket.

I flew over 2 days later and drove it back home (12 hour drive)

There was a serious vibration in the car. which I knew was the guibo the owner tried to say it was wheel alignment (yeah right) Was an easy fix though. Also the wheels were very gutter rashed.

Here's what it looked like when I first got it. removed the front M badge obviously :p



Once that was sorted the next thing was just a basic service as a I suspected the proper oil may not have been used.
After that a decent set of treads and a custom wheel alignment with a bit of front toe out.

I sold my 7 series soon after. I kind of miss it now



I drove the M5 every day for about 3 month before getting a company car. Then it just sat in my driveway for weekend use while the Cortina sat in my garage.

I did a few minor mods, such as a muffler delete and custom rear section with stainless tips. My rear section is a bolt on / bolt off setup so the standard setup can be put back within 5 mins. I'll never do that though because it just sounds too damn good now.

I then opted for some new wheels, I thought very long about the style I wanted. then ran into the hurtle of not being able to get with width I wanted without having to up the diameter. I originally wanted 18x9 & 18x10. but settled on 20x8.5 and 20x10

Here's the before and after







After almost a year of having two cars I hardly drove I needed to make a choice between the 2. The Cortina which I had as my pride and joy for 7 years. Or the M5. I chose the M5. I don't really miss the Cortina strangely. I took some last photos of the two before it was gone.





My next step with the M5 is suspension. I had the gaurds rolled last week and I have a set of coilovers that are going in tomorrow and will post some pics once it's done. I'm going to go lower and firmer. I'll update on that when it's done.
That's it for now.

Sweet ride!! Right hand drive? Glad you got the opportunity to grab a beast, I bought mine about the same way.

Very nice, and nice choice on the wheels. No many 20" look right on the e39, but yours pull it off nicely. :applause:

Thanks for the replies. My suspension is currently being setup. I'm going 30mm lower all round. maintaining the factory looking rake angle. My aim is to fill out the front gaurds with some nice stance, also tuck the rear wheels in. I'm trying to not to compromise road handling. I'm going to run around 1.5 degree rear camber with a true toe and have the front wheels toeing out slightly for a more agile feel. I stressed the fact to my suspension specialist I did not want to experience understeer. The guys setting it up are very renowned for their work. So I'm leaving it mostly in their hands.
Will get the car back on Wednesday. I'll take some photos of the look and how it drives. I might have a tinker around with shock stiffness afterwards for a bit of fine tuning.

IMO the key to removing understeer is to introduce some camber on the front, made a world of difference for me.

Yeah I do run a bit of front camber also. It does improve front grip some what. I found with a toe out increases steering response and turn in lift off over steer dramatically increases

Coilovers are now in. Wow what a difference, car is handling much much better now through the bends. Looks awesome and the ride isn't that harsh at all if anything I may even go a firmer spring rate on the rear. Here's the new stance

My next two steps is going to be clutch and brakes, in that order.

The Clutch I'm looking at getting is the UUC Twin plate feramic rated at 1000hp Twin Disk Flywheel/Clutchpackage for E39 M5 and Z8 – UUC Motorwerks Online Store
Sounds like an overkill but I'm notorious for wearing things out very quickly with my driving style. Also I want to future proof if I decide to go a supercharger later on.

Once the clutch is done i'll make a move towards some brakes as I don't have much left on my fronts. I'm leaning more towards a Ceika kit after chatting to the guy on facebook a bit the products are very well priced and he really knows his stuff. Will be getting some 8pot 405mm rotors. But as I said it's a slow progression thread so it won't be happening immidiately. maybe a few months before I do the clutch and hopefully the brakes before the end of the year.

Lol yes, the alignment is done. Toe out on front and slight camber, and rear is cambered out just enough to fit in the panels. I opted for not having the bump stop on the front just where it meets the guard. So I'll have to be cautious up driveways but will still have lots of travel on the front.

Those pictures on page 1 look great, just the right amount of drop. I know some have said over the past few days that they prefer the standard ride height, but IMVHO that makes a HUGE amount of difference.

Each to their own I guess. I can see the perspective of some saying best leave it original. Don't get me wrong there's plenty of things to be respected about the factory tuned E39 M5. As a carsalesmen I'm swapping into new daily drivers quite frequently and can't help but think that if this or that was changed this would suit me much better. I'm not really one to be 100% original and with an M5 there's many people out there that say leave it the way it was built. Truth be told though. My car is not to please others, it's to please me. I'm always open to what others say or think about my ride and in some way I cater to that (minutely) My eventual goal is to have a car that is very tastefully modified but streetable. It's an M5, it's heavy, but I love it. Eventually, I want this car to be a very quick and corner capable weekend car.

I'm even thinking about sacrificing the company car and going on a car allowance, buy my self a daily E38, keep the M5 and build a E36 M3 as a purely track focused car.

I'd love to have an E36 M3 track car, M5 weekender and 7 series daily. I'm slowly trying to build to that, focusing on making some money for the long term. Hence why I'm taking it nice and slow with the build and not dumping all cash into the project.

Thanks Angry dog.


I have a question though. I need to flush my radiator as the fluid is starting to look a tad off green. I've done a quick google search but havn't found any instructional demonstration could some one please show me or link me to a thread or step but step how to do this?

Hey mate
You will likely find all radiator coolant change info hidden in the various thermostat change threads.
Maybe if you haven't done stat yet it's a good time?

I've got a bit of a problem..

I'm getting power cuts around hard corners. anything under 3/4 tank. gets worse as the tank goes down. I've heard it's the siphon pump. I pulled out the fuel pump assembly today and everything looked to be in order. Is the siphon pump part of this assembly? There's two components under the rear seat. obviously one is the fuel pump... What is it the other? my fuel pump is okay. and quite new.

Please note: It is not a DSC issue. DSC is always turned off.
My engine is cutting power only around sharp corners, (not while going sideways)

There's a sender on the other side of the tank, check that. If you unlock the cluster menu, test #14 will show error codes.

If you see D7 and followed by some number, that's the issue. 10 to 15 minute DIY.
