The world’s BEST restored M3 CSL?

Where do we start on such an iconic car, and such an involved process.....
Join us for a transformation on what's turned out to be probably one of the very best 'restored' BMW M3 CSL's in the world!
This amazing 2003 E46 M3 CSL has 88,000 miles and in 2019 had a brand-new factory-assembled 'crate' Engine (part number 11.00.7.833.675) installed by BMW at a cost of nearly £20k.
Then in 2020, it had a bare-metal respray by multi-award-winning Andy Finch of Spikes Vintage Restoration:
spikesvintagerestoration.com/
So, it was no surprise that the Underside needed to match the incredible condition of everything else.
The owner turned to us at @RedishMotorsportbmw and in 2021 tasked us with creating the best Underside Restored CSL we've done to date.
** THIS VIDEO WAS RECORDED IN 2021 **
Within reason, this has turned out to be a no-expense, almost 'blank-cheque' Underside Restoration on one of BMW's most sought-after M-power models.
As you can see, the underside of this CSL was looking particularly tired in many areas due to dirt and road grime build-up over the past 18 years, but also the level of surface corrosion which has been taking hold of key chassis points couldn't continue.
All of these areas need addressing on most vehicles if you want them to survive in a hassle-free way, but especially when you consider the rarity and special nature of the M3 CSL.
We've restored several M3 CSL's over the years and more examples can be found on our KZbin Channel.

Did you see the 'Back To The Future' reference in the video?
If so, drop a comment with the time stamp so we know you were paying attention!
--------------
Notes:
Even though the vehicle has some (bolt-on) performance modifications like KW Clubsport Suspension, AP Racing Brakes, and a BMW Motorsport 3.91 CWP with Wavetrac LSD, it was decided that the chassis must remain original.
This is due to any potential future sale of this CSL to any worldwide buyer who may want to remove the bolt-on upgrades and have an OEM-restored CSL.
That meant NO RACP reinforcement.
The thought process behind this is that it already had the new BMW RACP (41.11.7.000.246) installed by a BMW dealer and we know more about the new RACP 41.11.7.000.246 than you could dream of.
We've fitted more than most places in the world, have dissected both original and new RACP's, studied them, R&D'd new products, and adapted processes for the new replacement panel for longer than you could imagine.
There isn't anything we don't know about E46 RACP.
In the UK, we are the pioneers of the modern E46 RACP Repair & Reinforcement Process including Load Relief systems.
We've been dealing with E46 RACP on a daily basis since 2011 and always have a 9+ month lead time for our E46 RACP work.
So, before you comment, please take a few minutes to look us up and see our well-respected E46 RACP history which stretches back over a decade!
Whatever you think is right or wrong for an E46 RACP - it does not matter to this owner.
So, thanks in advance for your E46 RACP concerns (of which I'm sure there will be many) but we won't be losing any sleep over it.
(Of course, if you have a similar project you'd like us to take on, we can discuss all sorts of RACP solutions for your vehicle).
See our RACP page here for more details:
www.redish-motorsport.com/E46M...
So, sit back and enjoy 2 hours of us discussing and updating on the progress of this Underside Restoration from start to finish.
If you have something similar you'd like us to work on (it doesn't have to be as detailed a project as this one) then do get in touch.
-----------------
NUMBERS:
This Underside Restoration took 194 labour hours.
Just the Parts costs for this Underside Restoration were almost £31,000 alone.
Then add in Materials & Consumables and you get an idea of the value of a project like this.

1. Amazing 2. Please start the vehicle at the end, I speak for everyone when I say we would all climax after hearing the engine run. 3. This type of restoration is much more valuable than buying a brand new car. 4. Thank you for this content.

[@chrisg4rr377]

I hope BMW headquarters appreciate the level of hardwork and attention to detail. Redish is probably the world leader in quality. Quite an accomplishment

if you were to record the process and upload those videos on KZbin, you would be making more money than you are getting paid to do the job.

Truly amazing. Love the high quality standard of your work. Looking forward to seeing more restorations.

[@SimonLive-iz7wx]

The switch back to the “welcome to another restoration” is just mind blowing. Not giving your car attention below is the same as sleeping with a dead body. You don’t see it but it’s still rotting. What an honor to get to see this work, legos and models for grown ups !

“Our very biased opinion “ that made me lol This is amazing work, the level of detail and love put into it shows.

Awesome detailed work as usual. Adding the transparent wax to all the zinc plated brackets and fasteners is a good extra step, tightening fasteners marks the zinc coating , also helps with the dissimilar metal corrosion issues on heat shields etc. 👍

[@teamgomez]

Incredible. Setting quite the high bar. I managed FA-18 restoration/repair and got to fly the product for 7 of my 19 years in the cockpit. If I were still in the biz, I would make the techs watch this (and likely catch flak for ‘gold plating’ lol). Such an amazing amount of work that could go to hell quite rapidly with ‘one loose nut’ behind the wheel (and I pray not in this case!). Truly amazing work; much to be proud of.

I am totally agree with you this underside restoration is better dan oem! Great work and satisfaction to watch this movie for two hours!. The value of the car after this will be also a lot higher. This is also a great investment i think this CSL is one of the best in the world!

Is it even a CSL anymore? All those gallons of cavity wax and seam sealer must balloon it to the weight of a regular M3! Just kidding, beautiful work as ever guys - gold standard of BMW restoration.

I delivered these new back in the day to the dealers, if I remember correctly did they not even have a radio? Top class work as usual, nothing but superb 👍

[@stephenmartin5171]

Amazing beyond exceptional. I watch all your videos and I am amazed at how much effort you guys put in. One suggestion I would like to know is pricing and pricing options. Doing my own small bits as I go along on my project I understand that BMW likes to charge well for these parts. So a pricing option as you are discussing the different jobs would be a very welcome addition… 👌👌👌 In any way please keep these videos coming.

[@odortiz]

amazed how much work you guys do to make it better and more durable than stock. have you had any customers come back for a checkup after a couple years to see how things ate holding up?

[@rssagoo5780]

Words cannot describe

[@bobfrankish8883]

Unbelievable job guys, well done. Just a couple of things: the POR15 metal prep. is in my opinion the only thing they do that actually works and is worth using. However, try and get hold of some Fertan and give it a try, it really is the best rust converter out there, and the only one I have found that works well on clean bare steel. In fact, I( have plenty of it left over, I'll post you a sample when I get a minute, see what you think. If you reply to this comment and tell me who to make it FAO. Well done again.

Excellent job. Also , my dream is to buy and restore an e46 m3 , just regular one😊. Thank you for showing way.

[@gingerbreadman2488]

Beautiful work. Can I ask, why did you use rubber bushes over polyurethane for the rear suspension?

[@Mertzy63]

What seam sealer did you use for the final product? I live in the states and wanted to try and so something like this on my e36. The work that went into making this csl look so good is awesome btw!

[@studiomwg]

Do POR15 or similar rust converting acids work within closed spaces, like the rear wheel arch? I would think that for lesser repairs that it would be fine, and then cavity waxed.

[@E90dga]

Hi. In older videos u mentioned that you are painting headshield. What paint you use back then? Chrome or Silver? Heat resistant or not?

[@friguy4444]

I live in western Canada and I always thought that because we have so much snow and then they salt the streets every year that we must have the worst vehicle corrosion and rust anywhere in the world. But it's just no where near the amount that is in the UK and that whole area near the sea and with the rain and wet all the time (At least that's what i expect is why it's SO bad there). It always amazes me how much the damage is with cars from there! I guess because it's in the very atmosphere or something like that that it rots out the insides of everything as well as under sealers and in joints etc. with cars here we get terrible problems with rust eating away where ever the snow filled with salt sticks to the car and is flung into. Where ever those areas are is where it rots. But as shown on so many UK cars it EVERYWHERE! I do wish we had Redish Motorsports shop here though as you are THE BEST! and it doesn't seem like your prices are quite as insane as here. But I could be wrong on that. Thank you for the great video and sorry for the very long comment.

[@brunoduarte7532]

My dream car....

[@walterhernandez9112]

Beautiful work, I wonder if anyone knows how much it cost to get that kind of restoration.

[@elroyfudbucker6806]

At 1:22:05, the purchase cost of all the fixings & brackets would run to about AU$3,000 plus another AU$1,000 or so for the plating. All up cost for the underbody work would be about AU$40,000 at least or about 1/4 to 1/3 the value of the car.

[@bcbcfilm]

@RedishMotorsportbmw what brake master cylinder are you running with BBK?

[@bobsmotorworks]

Great work guys. Underside looks as good as new. 😎 I must ask though, what was the reason for why the underside was restored but the RACP wasn’t reinforced (ie with the plates kit etc)?

[@--LZ---]

As he said at the start, it seems that the complete RACP was replaced. The later models have a different design inside so i guess the owner just wanted to keep it as original as possible.

Is this level of corrosion common with cars that live in wet areas like the UK?

[@cdeprima1209]

Or just touch it up with Red Rustoleum primer for parts and fasteners; just spray it, no disassembly required, really, kills rust and prevents future rust, no need to finish! Cheers!
