Finally I find someone who’s more of a fuss-pot than I am.
Seriously… enough with the new caps… get out and rag that thing before the summer’s over!
I think i may get this car out by the end of the year but yet again i put a plan in my head for all that i want to get done before im happy with it and that list seems to go on and on .

A bit of a more exciting update on the progress of the car this time .
After i picked the car up and had a good look round and everything is in great nick but the one arear that could do with some attention was the rear subframe as this had some surface rust and could do with a tidy up .
After looking at this more it would make more sense to remove the whole unit to be able to do a proper job and also it would make it easy to fit some new parts when it is off the car .
First was to un bolt the coilovers and all the brake lines , handbrake , ABS sensors etc .
And after an hour or so the rear subframe was removed .
Then it was on to removing the rear hubs / brake discs and hangers .
Then after a good clean up and some sanding of the surface rust the unit was looking much better and ready for the next stage .
Then it was on to removing the stock OEM rubber rear subframe bush .
With all this prep work done i could then set about applying the rust converter .
After giving this a day to fully dry it was then time to give a few coats of black stone chip to give more protection and tidy the subframe up a bit .
Then i fitted some upgraded Powerflex polyurethane bush in a Purple medium compound ( there are Yellow soft , Purple medium and Black hard that can be had in this range )
And then on to the last part of fitting some new Pure motorsport rear camber plates .
The come in different sizes but I have gore for a 1.5 deg set up as this has been recommended as the best set up and should give around - 2 deg of negative rear camber when installed as the cars run 0.5 deg as standard .
and installed .
Then to re install everything back on the rear subframe .

Another part has been installed on the car so the list of things to get done is going down .
One part of the car that i wanted to look to change / renew was the engine mounts as the car is still running the stock Renault units that will be getting a bit tired by now .
First was to remover the OEM upper engine mount .
I ordered a new OEM Renault unit to replace the old one .
New and old unit .
To add to the new mount i have ordered a Powerflex insert .
Then the easy job of installing this on to the new OEM mount .
Then all installed back on the car .
I will look to change all the mounts on the car and there are x 4 of them so there will be another x 3 left to do .

Nice work on the rear beam. I’ve heard stuffer upper engine mounts can be pretty hardcore. What’s the NVH like now?
I will let you know as the car is still up on axle stands as I have a few more bits to do .I had this type of mount on my old Fiesta ST and that was ok so I'm hoping that this will be the same and if not I can allways remove it .
After installing the upper engine mount this week it was time to change the OEM upper engine torque mount .
First was to remove the OEM mount .
The stock OEM mount had a bit of play in it so was due a change .
The new unit is an Airtec polyurethane unit in a Purple grade middle stiffness .
Then to re install the new unit .

Keeping the mount theme going next was to look at the lower gearbox mount ( dog bone mount )
I found out that the car is all ready running a Vibra Technics lower gearbox mount but having a look at this it looked a little worn but still in good shape but as im changing all the mounts on the car i thought i would get a new unit .
First was to remove the Vibra Technics mount .
old and a bit worn but still in good condition .
I have ordered in a new Airtec unit again in Purple grade stiffness .
Then re installed with the new mount .
That just leaves me with one mount left to do .

So on to the last mount on the car then .
The gear box mount on the 250 does not have an aftermarket replacment but you can fit the uprated OEM mount from the 275 modle that is stiffer so a new one of them was ordered .
First up was to remove the old 250 gear box mount and for this you need to remove the battery , battery tray , ECU etc .
One of the common faults with the gearbox mount is that the bolt is week and can snaps over time so i removed this with caution .
Old mount removed .
Old part number .
New 275 mount .
New part number .
New and old monut side by side .
I also replaced the gearbox mounting bracket .
Old bracket .

New bracket .

New and old bracket side by side .
The last part to change was the bolt for the new bracket so the OEM renault bolt that is rated at a 10.9 tensile was replaced with a new unit bolt that is rated at 12.9 tensile .

And then the new mount and bolt installed .

That is now all of the engine mounts changed on the car for new upgraded units .

Looks ace. Any feedback on the Fiesta now the mounts have been changed, I'm contemplating doing mine which is now on 80,000. Cheers
Still have not driven the car yet as I still have a few things to do but will report back when it is back on the road .My one is on 97,000 miles and the OEM mounts were ok but were getting a bit tired so this should firm things up but as I have a mix of polly and rubber im hoping it will be like my old car set up giving more stiffness but not causing NVH issues .

Great thanks, yes mines lost some of the sharpness it once had so I'm hoping a similar approach might improve the handling again . . .

Love the way most of the pictures are of the car floating in midair without any wheels.Reminds me of when I bought my Megane, ended up sitting without any front suspension for a while while I tidied up the car

You are very correct and i have only driven the car once when picking it up 4 months ago and from then it has been up on axle stands and will remain like this until i stop fiddling with it Reminds me of when I bought my Megane, ended up sitting without any front suspension for a while while I tidied up the car
Note to self must stop buying more new parts and get on finishing the car and driving it !!!!!!!!

Amen to that! You’ve got all winter to tinker with it.. get out on the road and kick it in the balls while there’s some daylight left
I know best summer we have had and I'm wasting it .I have a track day planned for this month but TBH I won't have it ready then and October is looking doubtful.
Are you still looking at next month to get the Atom out on track ?

Even if you get it into the road, you can do a few hundred miles of ‘shakedown’ which should give you the chance to iron out any frustrations before your first trackday. Come on… you know you want too I have a track day planned for this month but TBH I won't have it ready then and October is looking doubtful.

I’m all booked for the Atom to go on track. 14th of October. At Pembrey. In Wales.
I must be out of my mind. I’ll pack my scuba gear

Tbh i should have just driven it over the summer and then spent the winter messing around with it .I’m all booked for the Atom to go on track. 14th of October. At Pembrey. In Wales.
I must be out of my mind. I’ll pack my scuba gear
I have not done Pembrey but it look like there is lots of run off so you should be fine if maybe a touch wet and cold
