Cracked on with the trailing arm bushes tonight. Again with my best guy Mike helping out!

First up was stripping off the metal rear heatshield and the rear lower brace bars.
Image

Once this was done the plastic housing that fits against the sideskirt under the trailing arm bushes has to come off.
Image

With that out of the way, we then loosened off the bolts holding the bush housing up to the chassis.
Image

Quickly followed by un-clipping and detaching the cables and clips that hold the brake pipes in position!
With that done, we could pull the arm down and set to work using my new big black tool to remove the bushes.
Image

With the bushes removed, using a medium grade of emery cloth, I cleaned off the aperture of which the bush sits in and cleared it of any corrosion or debris!
Image

The original bushes that came out were actually in pretty damn good condition! Far better than I expected for a 70,000 mile car, however the amount of play before and after was an absolutely huge difference!
Image

With the Powerflex bushes lubed up handsomely I then pressed the outer one home by hand (easy) then after realising the inner one was a bit harder, used a few components of the big black tool to make a temporary press!
Image

Re-fitting everything back in position was relatively boring, so I didn't take any further pictures, however I have a video of the bush remover tool in action which I may pop up earlier depending whether it's any good or not!

We used tip-ex to mark the housings to try and get the alignment back as close to where it was as possible, but the car will be having a hunter laser alignment hopefully in the next couple of days, so that'll all be cleared up!

Really glad I went ahead and did these, despite not really needing them. - I'll report back with opinions once I've got the Hunter Laser alignment done!

Hunter Alignment tomorrow evening with a bit of luck!
Unfortunately a job I won't be tackling myself.

Managed to find time the other night to get my technician John to have a look at the geometry alignment :)
Took a couple of photographs along the way.

Here it is on the 4-post ramp with the Hunter Alignment system...
Image

Alignment system hubs clamped onto the wheels
Image

Up in the air for a few adjustments - Rear camber and toe were out slightly
Image

Rear end readings: Spot on!
Image

I forgot to take a photo of the front readings, but all was spot on!
The toe was at 0˚05' on both sides, Camber at -1˚21' (L) and -1˚25' (R) - This is adjustable however we didn't have the correct tool for it, so this will be done again at a later date - Hopefully when I decide whether to go with new tyres, or new wheels and tyres!
Caster was a healthy 5˚01 (L) and 4˚51' (R) but isn't adjustable.

The car now drives miles better. Steering feels more direct and I have less pulling over lumps in the road.
Mega happy :)

Next up, a good clean.

Good results mate :thumbsup: makes such a difference having the alignment set up correctly.

At the weekend I finally got around to giving the car a good clean!

First up, A quick rinse with the pressure washer to get rid of any loose debris
Image

Then a pre-wash, a rinse, then another wash using the good old two bucket method and a microfibre wash mitt
Image

Another rinse and it's looking better already!
Image

Next up was to clay the paintwork on the car, For this I used a medium Bilt Hamber clay and a home mix of clay lube.
Image

Just a small area of the paintwork on the roof brought up this with just one pass! Looks like it hasn't been done before...
Image

After 2-hours of claying, the paintwork felt a lot smoother, but needed brightening up a little
Image

So, On the recommendation of a friend, I gave the car two coats of AutoSmart Platinum Polish. Very similar to AutoGlym Super Resin, but with far less powder.
Image

After drying with an Ultra Plush Microfibre Drying towel, it was polishing time.
Image

With the polish applied and removed, We're now onto the finishing coats! I've chosen to go for FinishKare FK1000P after a lot of recommendations on detailing forums.
Image

FK1000P Applied
Image

2-Coats later
Image

Next up, The leather... Due to me having no seat cover and having worked on it quite a bit in the past few months, the drivers seat had got a little dirty.
For this, I opted to go for a leather cleaner and conditioner kit from Gliptone - Basically - Gliptone are a leather producer and one of the worlds finest leather dye/paint companies, so they know exactly what they are doing when they make their leather care products!
Image

Needless to say, It came up absolutely beautifully and I'm now happy that the leather is protected and conditioned!
Image

Another cool by-product of this stuff, is that my car now smells like a leather factory! Such a nice smell :)

Anyway - Here's a couple of finished pictures:
Image

Image

And a couple of beading pictures for those interested in how the FK1000P works with rain :)
Image

Image

Image

Overall, I'm happy with the products that I've used, but I'm thinking maybe a little later on in the year, I'll have the paintwork professionally machine polished as there are unfortunately a number of marks that I'd like to get rid of and some areas on the bonnet where it looks like someone has made a poor and thoughtless effort of removing bird poop.

Next up, Hopefully discs and pads once they arrive with me from Italy :)

That clay bar was fairly dirty! I can imagine the lower half of the doors and side skirt panels being even worse? Overall it's came out great 8)

Any particular discs & pads you are getting for them to come from Italy?

Strangely enough, the only two surfaces that were this bad were the roof and the bonnet. Everything else was pretty good overall! The bumper, the tailgate, the skirts, doors and wings only needed one pass!

Tarox 'D95' Discs (Heat Treated, Anti-Corrosion Treated , Countersunk Drilled) and Tarox 'Strada' Pads (moderate fast road use).
They normally only offer their G88 (40-grooved), F2000 (Swirl Grooved) and Sport Japan (Drilled/Slotted) rotors to UK customers so I'm having the ones I wanted imported by Tarox UK :)

Good choice 8)... You are certainly getting the zed into top shape that's for sure.

I've found some wheels that I really like (And can get Michelin Pilot Supersport Tyres for) too but I'm still umming and arring about taking the car away from the OEM+ looks that I normally go for :(
And I'm not too sure how it'd look with 19"s on the Eibachs or whether I'd need to change for the H&R's.

Probably not something that I'll be doing any time soon though.

After a quiet period in which I've been mostly chasing tail... I've received my made to measure stainless steel pipes!
My plan is to give the Coupé a little more aural presence by removing the centre silencer!

Here are the pipes:
Image

And here's the offending silencer: (Photo borrowed from someone on Z-Post)
Image

I'm gonna have a word with our Tech genius guy Wayne and get him to do me a little Drive Away video of the standard exhaust, Then keep my fingers crossed that I measured it up right, then re-measure it all again another two or three times before cutting and joining... Then get another video on the same road with the silencer bypass pipes fitted :)

An update maybe later this week on these. :)

Saturday morning job: Get rid of the centre silencer!

First up, Here's the silencer...
Image

Cutting the old one off. I used an air speed saw for this. It took quite a while, but wasn't difficult.
Image

With the four pipes chopped, An axle jack saved me from having a sore foot...
Image

Comparing the silencer with the two replacement pipes - Weight wise, around 2kg has been saved - I quite simply couldn't believe how heavy that tiny little silencer was!
Image

Pipes in place sleeved over, sealed with silicone and fastened up with Mikalor SupaClamps
Image

And finally the finished thing:
Image

First impressions: Driving around normally there is absolutely no increase in drone or any horrible resonance whatsoever.
The tone of the exhaust has changed slightly and if anything feels a little 'deeper' than it was before.

Volume wise, there's a little difference, the car sounds a bit more like it should have done from factory, but it in no way sounds like an aftermarket exhaust.
I'm quite happy with it so far.

Here's a quick crappy rev-up video I took with my iPhone.

I need to get a start on mine. Have you chosen the wheels yet?

Kind of... I'm not sure though. Plus other things are 'diverting' my funds at the moment... Which I'm not too sure whether it's a :thumbsdown: or a :thumbsup: yet...

Same here, a refurb is half the money toward decent reps and my wheels def need doing. Then there is the added cost of spacers. I've just bought h&r springs and I'm keen to get it all sorted.

Did you buy the spacers online? Might just bite the bullet on some??
