Looks AI! So cool
I recognise the driver
So this year 12 of us have booked May to return to the Ring, having to rent two houses this time 
Second trip last year she started to feel a bit wobbly at high speeds and at 168k miles it’s time to give the girl a re fresh.
Laid everything out yesterday to stock take and I think I’m very nearly there.
Also going to do a new article on shift pins for the Z4 gearbox, can’t find anything on the internet about it, can really feel how notchy mine is.
Also thinking for a bit of fun wrapping it in something. @Holliez4 has an idea of something satin.

Good for you mate, did you build it yourself
Hi Monica are you any good at changing timing chains ?
Right! Finally found some time to strip the coupe apart reading for this years Ring trip. I’ve pre built the new subframe and arms, everything’s zinc/powder coated.
Pre built subframe
car airborne
these wheels will be painted back to their former glory in the future
the noise maker mod
didn’t take long to start getting everything off.
on closer inspection can see the front bushes falling apart
explains all the movement above 140mph hard cornering.
oh!
Will give the mounting points a clean back n re seal. Also got new brake lines front to back to fit.
starting to strip so we can move the diff and shafts over.
next up remove the gearbox ready for overhauling.
clutch is original 168k miles and 40+ track days.
had some life left in that disc
Release bearing well worn in
loads of life left….
Next for removal is the front brakes, these have had some serious heat treatment last year. I have wavy heat ripples.
I have new discs and new Ferrodo DS2500 pads to go back in

Car now fully stripped. Time to start fitting new bits.
I’ve noticed of late the gear change getting notchy so looked on real OEM to see if you can do the pins on this ZF box and found you can. Cost me £136 for the kit.
Doing gears 1-4
same method as we do on the Z3 box.
big boy roller pin.
was a simple job overall.
might do a separate article as I don’t think this has been done before.
Got my moneys worth from those brakes, pads were so crumbly
diff moved to new subframe
outer arms added
just waiting on a few more bits to arrive now.

Made some progress last weekend. Annoyingly not as much as I hoped. Turns out the brake lines were wrong so we focused on other things.
Front brakes all rebuilt. Fresh discs and a set of Ferrodo DS2500 pads, can lean on these all day long and they never complain.
wheels looking like they need another refurb, hoping to go back to the original 2 tone
got the rear brakes all together. Saves the work once the subframe is up. Also cleaned them up with some fresh paint.
getting excited
last minute plan to replace the selector seal as it was weeping.
got some nice upgrades in the form of race mounts and some fresh gearbox mounts.
while I was under the car I noticed the subframe mount paint had cracked, as it will be years till I go under again thought I would take it back to bear metal and re paint.
the clutch kit arrived just in time. Can see quite a difference in quality when you compare a Sachs kit to an LUK kit. Plus the price is nearly double now.
now waiting on the last brake line to come in.

Been on quite a journey this coupe. 
Getting excited to drive it,Been on quite a journey this coupe.
I don't think there's not any item on this car that's not been removed or replaced.
Not sure about that mate, I had to take your engine out just to remove a stuck boltMore 'Triggers Broom' than mine now Lee
Got a good 3 days on her to finish off the final touches. First job was getting the rear subframe in and torqued up.
then I started assembling the clutch and gearbox parts.
this was tough. 60kg off the chest up and in. Was actually very easy, these you have to be careful installing as the majority of the bolts are Ali.
another little upgrade going in. Vibra-Technic engine mounts.
old soggy mounts
Nice race mounts
next in was the prop.
and torqued the arms along with setting the camber and toe to mid settings. Few shields later and the rest was back together.
Everything went perfectly today. Down on her wheels and so excited to test drive
after getting back the rear end now sits up high on firm bushes.
test drive was incredible, gear change is so sharp the clutch bite is very low. Just need a good clean and to setup the Geo. Need to get used to how she feels now.

The Ring trip was a huge success. The car was the best it’s ever been. She felt so stable, brakes were crisp. In the last month I’ve rebuilt the rear subframe with new bushes and poly for alignment, new clutch and new gearbox shift pins, new discs n DS2500 pads along with vibratech race engine mounts.
En route to the tunnel, mate Matt in his AMG
on the train
then by 4pm we’re sitting at YouTube corner.
This time we book two houses and one house needed to have a big balcony so we can take our pizza oven and bbq.

Our house which the southern lot stayed in.
over the weekend I managed to get 14 laps in and set a new PB lap of 8:36 gate to gantry chasing Matt in his AMG, could have knocked a bit more off as we had one yellow flag. In all though very impressed with the coupe, she’s in the best setup shes ever been. This brings me onto making a huge decision to sell the coupe. I’m planning to move onto something slightly bigger, will be dining some final touches before listing her for sale.
