Yep that is exactly the same as mine Mikey, looks standard once its been powdercoated black.

it still varies quite alot from the mk5 one tho

Yeah i did mine black in the end, and the Anti-roll bar gold to match me brakes.

turboboss...

I am very interested to see how the rear beam is made adjustable??
Have you any pics??
I have got a zetec-s rear beam to go on2 my fiesta, which i have been told makes a lot of difference to the handling .... but to make it adjustable... sounds even better!!!

[BUTRE]

opps... just opened a new topic about FRST handling tune.

http://www.fiestaturbo.com/phpBB/viewto ... 294#974294

turboboss, would like to know details about changing castor.

The mk3 chassi can be made to handle!

Its like the tyre comercial: "Power is nothing without control"

[Red16]

is the zetec s setup the same as the puma set up?

when i had my fiesta rst about 2 years ago people were on about switching the frst rear beam etc for the puma one, as this improved the overall handling, however i never had it done so cant comment personally.

[turboboss]

people i will tell you more about the adjustabe rear beam and lower wish bones once i make the trip up to zoo motorsport, they are doing them as we speak so should have them fitted and car set up before the end of the month i never heard of anyone making the rear beam adjusable ontil i phoned them about an inlet manifold zoo motorsport specialize in making custom parts for strength,durability and to improve the handling karl bromley at zoo did explain how it works to me i just cant remember everything but soon all will be revealed

I find that my turbo handles better than my si. My turbo is standard and holds quite well untill high speed. the si is on a 60 drop and its all over the place. i might end up putting the rear end lower on it so it is more like the turbos. i read an old old old rally sport news mag and when they researched to build the turbo they lowered the rear and made the dampers stiffer so obviously they saw a problem there. All after market suspension kits loose that thought and i find that the front always goes lower than the rear.

How do you have yours??

what suspension are you using?

depends on how you propose to do it, you could end up just make it worse

[DR1984]

I find like sunil that when driving a little harsher into corners the back
snaps and lifts. It also makes an annoying knocking noise which to this day
my local 'fraud' dealership does not know what it is.

Been looking into Z-S rear beam as to have bolt on rear disc. how hard
would this be to do.

[fiesta_fras]

my rear beam has a strip set half way inside the V shaped bit, and poly bushes and a FRST ARB which has had added mounting points in the middle of beam as when as on the sides.

perfect balance of stiffness and handling

[Ollybee]

Got a strut brace on the back of mine and it really stiffens it all up. You can feel it working even in slow corners and when the back end starts to drift it's sooooo much more predictable and controllable.

A very good £35 spent there!

[Chris_S]

I'm thinking of making subframes for mine to help stiffin it up a bit.
Anybody any thoughts on this I might even get round to making a couple of sets to sell (made to order).

couple of drawings of your plans would be good

[Ollybee]

HOLY CRAP!!

I put some unused Goodyear NCT2's on the back last night and on the dry they are beautiful!! Damp round abouts are another matter, however highly entertaining. Dont think I have ever has a car so sideways and managed to catch it. I love my Fiesta

I also like the expression on the faces of old people when you catch a big slide!

[turboboss]

next week i will post pictures of the mk3 fiesta adjustable rear beam,rose jointed adjusable front arms and the cossie spoon style inlet manifold should all be done by then

Long time no see, hows things mate. Sounds like your motor is coming along , do you ever stop modding it lol. Will have to have a look at your new setup when i next see ya around. Ive got a little engineering place in Taplow by the Sainsburys working on my adjustable lower arms at the min. Im not going as far as adjustable rear though.

[turboboss]

hi m8 car been on and off the road at the minute just had simpsons race exhausts do me a tubular manifold for my gt25/40r roller bearing turbo so turbo placed over my gearbox karl bromley at zoo motorsport use to race mk3 fiestas and the ka and have carried out lots of mods to improve the handling he is doing me the lot plus a full suspension setup..yeah when is it going to stop hopefully in the next two months im having a new zetec block being built for me as we speak with steel rods and je pistons custom newman cam with soild lifters s8 ecu cossie style inlet manifold and 100 shot of direct port nos and to sort out my cts gearbox i am having trouble with my quaife diff.. hows your car getting on? have you had it mapped yet seen you a few times on the A4 car sounds angry are you doing any track days or rwyb this year

Im getting an exhaust made up at simpson racing eventually aswell , went down there for them to sort out my de-cat and there work is proper (insert ghey rap term) so im gonna ditch the magnex for one of there systems. Aint had mine mapped yet, still gotta a few thigns to do first like the exhuast and i want a new inlet mainfold aswell. Whats up with your quaife diff?? i bought a stg2 from Bernie a few months ago. Aint done no track days or RWYB yet but i did do a grudge match with Performance Ford a couple of weeks ago (http://www.fiestaturbo.com/phpBB/viewto ... highlight=). Will be in the March issue, managed to get to 60 in the 6's and 15 sec qtrs in the damp. cant wait to get it mapped and run it on a dry day with me adjustable lower arms. Reckon it will be in 14's easily. Saw your feature in Performance Ford not so long ago. aswell , well done. You got any parts for sale that i might be interested in? you must have loads of spares the amount times you've changed things round you nutter

[dannyboy]

Hope you dont mind me asking turboboss but how much did Simpsons charge for the exhaust manifold?

Dan

[turboboss]

simpsons charged 850+vat the welding proper a work of art but for some reason the car not as loud as before different exhaust note just waiting on zoo motorsport to finish off my front arms which are nothing like the adjustable arms that fiesta frenzy do these are custom steel tube with more adjustment you have adjustment on the tie rod ends and also the where it is bolted to the car body then my rear beam is adjustable should have pictures on friday i will be selling my 2.1 zvh block,cossie L8 ecu with pectal board i will have to see what else is lieing around, sunil those times are good especially for a n/a car get simpsons to do the rest of your exhaust system the works excellent ,i want to get down to santa pod as soon as possible but first i have to run my new engine in

Let me know when your going to the pod and ill probably come with ya, would like to get mine timed again and would be good to see your beast go up the strip.

[turboboss]

no problem mate........ just a few problems with my cts stage two gearbox like when i activate my nitrous in fifth gear i get loads of wheel spin from one wheel which shouldnt happen hopefully when i fit the new engine i can have my quaife diff repaired also zoo motorsport are doing me some uprated drive shafts dont want to snap them like last time i was up the pod

there are other diffs out there worth considering

[turboboss]

the only other one i know is tranx which is the plate type any others?

[FezzR]

the only other one i know is tranx which is the plate type any others?

yes but cant remember,
trying to find now

[jayrs]

cant say i have really had a problem with my handling, its slipps a littl and its come out a few time's, but have to say my mk2 XR2 handled better as standard.
got avos on now but not really given it much yet, would agree that the back beam is a bit flimsy and could do with being a little tighter

[Spanthefestaman]

They should have come with an indepentant reap suspension set up. or an Xr2 style rear beam.

Ive got a few ideas in my head that i would like to try but i dont have a spare beam or the kit to have a play. Basically a steady bar from the centre of the axle to the lower shocker mounts. Would be pretty much a fixed bar one to each side. Could be adapted from a xr2 rear tie bar (cant [ERRR] of the proper name. Hard to make you see the pic but i think that it would minimise twist in the axle. Also my mate are into R5gt and they run the front end lower than the rear and say that thats the best set up for handling. And they use a similar torsion axle to a point. Il try and make up a pic of my idea.

[MAD_Adamski]

i haven't tried my new rear ream out yet but my rs handled brill before with koni's and 15'' rims it was a great handling car so now with my zetec s beam and focus disc set up the hanlding [ERRR] be top notch ...


i think trying to fiddle with more camber and stuff on the rear is goin a bit OTT well for me anyway, its each to there own but i'm quite happy just slapping a stiffer beam and wider track on rather than experimenting with stuff

[PUREtom]

Will the zetec S rear beam fit straight onto the fiesta mk3 si?

Got a pic at all?

[MAD_Adamski]

the beam should fit straight on yes mate heres a couple of pics have a few more in my gallery

[sjoyce666]

Ian get on passionford and have a word with a user called MEF, he does suspension kits to change the rear fo an escort so it can run coilovers so im sure he can sort something out for you or give you an idea at least as its not as easy as fitting coilovers on the rear fo a fiesta so he knows a thing or two

at least worth a try

I've been doing calculations all morning concerning roll stiffness, weight transfer etc, and just found this thread. My car used to be pants, so on went the 2i wheels with 185/60/13 tyres, which made it sharper. Then came the 195/45/15 wheels/tyres, front anti-roll bar and Gmax suspension, and a fast run on the twisty roads didn't give me one moment of understeer, nor end rear end action.

I drive my car pretty damn hard on wiggly roads and the back end hasn't been a problem once. The Metro loses the back sometimes, but never the Fiesta. The front end goes before the rear.

Like I say, I've been doing quite a bit on roll stiffness and weight trasnfer recently, and going through the calculations shows up a lot of factual information which throws your old beliefs out of the window. In short, I would formerly have thought "My car's understeering, so I need to put a stiffer anti-roll bar on to stop it rolling and sliding". The truth it, the front needs softening in relation to the rear, which could be accomplished by reducing the roll stiffness, increasing the rear stiffness, or a combination of the two.

That said, increasing the roll stiffness at the rear would seem to be the best option, as the front end certainly doesn't need to be any softer on my own setup. The roll's not bad on mine, being a little stiffer would be good. Increasing roll stiffness doesn't alter the load transfer in lateral acceleration, only the rate of load transfer. This would result in sharper turn-in and less body roll.

Increasing the rear roll stiffness would shift the load transfer towards the rear of the car, putting more weight on the tyres and giving more grip, taking away a little from the front.

To model the car's roll characteristics would be a damn hard thing to do, and would be the way to calculate exactly how much needed doing to the back of the car to get a fairly neutral setup. Roll centres would be reasonably easy to calculate, but the sprung centre of gravity would not be as easy.

Long story short, after all this babble, is that "suck and see" with rear beam stiffening would appear to be the best way to get the handling you want! I've babbled on above to discuss the true reasoning behind stiffening the back of the car up, and the welded webs appear to be a pretty good way to do it, and much easier than a full beam transplant!a

[FezzR]

cant believe i just reas all that

cheers james im sure people will fine that interesting, i have no interest in me fez at mo tho

as for the adding webs to a beam as apposed to a swap, most people would probably end up removing the beam to get it welded, and so little advantage if any, i would much prefer the ZS beam to a welded mk3, mean reason is the redesign of the mount between hub and beam, which to mean is a lot stronger and better design

[heeman10]

I would swap straight to the ZS beam if it didn't mean shunting the rear track out to an arch-interferring width, which is why I'll be welding a FRST beam when I attack that part of the car. A guy came round to look at the Fiesta yesterday to price up a respray and a couple of bits...£1500 + VAT

Ian - I bet you lose interest in yours quite a bit, you are certainly going for the in-depth stuff rather than just making it run and driving it. It'll take you longer, but be more satisfying in the end This weather hardly encourages you to work...I've just come outside now to spend the last two or three hours on mine before I have to go back to uni and it's snow, and -1 degrees C Gotta keep cracking away though, it's been great just to see it again after so long
