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:

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 Youtube Channel.

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:

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.
