So this year 12 of us have booked May to return to the Ring, having to rent two houses this time :D

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.

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

the noise maker mod :D
IMG_5569.jpeg

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.
IMG_5587.jpeg

clutch is original 168k miles and 40+ track days.
IMG_5586.jpeg

had some life left in that disc
IMG_5588.jpeg

Release bearing well worn in :D
IMG_5593.jpeg

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.
IMG_5611.jpeg

was a simple job overall.
IMG_5614.jpeg

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
IMG_5616.jpeg

diff moved to new subframe
IMG_5617.jpeg

outer arms added
IMG_5618.jpeg

just waiting on a few more bits to arrive now.
