Good evening Slotfriends.
Today we're 4 weeks away from travelling to Leamington Spa for the 9th Edition of the Disca Le Mans 24hrs....and it has been more than six months since my last "confession". One which I broke off quite abruptly by the way. I still owe you the rest of that story
Time for an update on my Mission8 also know to insiders as "Mission wait"
Because for many months after posting the first publication photo's of the 3D printed master...al I managed to do was cut and test fit one master for the right hand headlight lens and one for right hand the tail light lens...not much to write a progress report on.

M8 waiting game
At first the M8 was intended to make its debut at the DiSCA finals in Barcelona on Nov 4th, remember I posted those publication shots in August 2019...so plenty of time right?.
Well I got a bit more involved into the organizational work for that final than was provisioned ......so....not enough time to finish the BMW....raced the Ford GTE...again...
...and plenty of time till the next event in Januari right?
So November flew by, but by half December Stefan Nalbach (Prospeed) send me the first renders of the Hybrid M8/M6 3d design.
The M8 Mk1 chassis was a hybrid version that allowed us to run and test the M8 Chassis under the M6 GTE we raced last year at Suzuka.
As you can see its got the M8 diffuser attached to the motorpod . The same way as first used on the Ford GT.

Got the chassis printed in time for the dec 15 test we had @ the Suzuka track, December is always busy work wise but with a last minute push we managed to get the Hybrid M6/M8 chassis assembled and up and running under the "old" GRP M6 body.
I had also modified the original M6 chassis mounting the diffuser to the NSR SW pod "Ford Style"
The new Prospeed M6/M8 chassis is similar to the one Prospeed used for their C7R corvette they raced at LM 2019.
It has a Prospeed shortcan motorpod with a 10˚AW/SW configuration and 1,0 mm offset. Attached to the rear the "now correctly sized" M8 rear diffuser.
Had to shave 0,1 mm off the bottom of the strakes as they touched the track on the first roll out (later I found out that I had not tightened the diffuser screws completely)
Must interesting was how the Hybrid chassis with its narrower and more forward position of the side suspension compared the old NSR podded M6 chassis.

The first test went very well, the new chassis was still a bit slower, but showed promise. I'd figured that we needed a bigger offset pod to get it on par with the Ford, had a quick chat with Stefan Nalbach who immidiately made one and had it printed asap by Shapeways. It arrived just in time to be assembled and run in the last test sunday before the Suzuka 6hrs on Jan 20...
But there things took a bit of a downfall.
With the new Motorpod the M6 ran well, nice and smooth...but when we checked the times was 3-4ths slower than the Ford.?
And when we start pushing to match the Ford's times the BMW became very unpredictable ?
We switch back to the "old" prototype M6 chassis..and same thing. 3-4ths slower than the Ford and unpredictable when pushed hard.
We tried several different set-up changes to make the M6/M8 behave...but it would'nt...and then we ran out of time.
With still a ton of organisation work to do in the week till the race and with no gauarantee we would manage to solve the problem during saturday's free practice.
...we decided to not run the M6/M8 and race the Ford instead....again.
A good call as it turned out the weekend after. First of all with the more stable Ford even though I was waisted as usual we did manage to take 2nd place overall and win our GT class.
But by just one lap difference from the second placed GT car: the Prospeed Corvette C7R.
By now it was Jan 31st which was the cut off day, last day, according to DiSCA rules, to pay the remaining enry fee and make changes to your car choice for the LM 24hr race.
And although I had an idea on how to fix the problem with the BMW chassis....we decided to go for the plan B and switch back to the Ford GT. Better safe than sorry.
To be continued
With kind regards
