Hi guys,

Im looking for 6 degree rear beam for my Escort Cosworth if anyone has one to sell or know of one available.
(couldnt post in parts wanted as dont have access being a newbie)

 

Worth contacting Mk-Motorsport, they did mine recently - turnaround was pretty good around 6 weeks, communication wasn't amazing but was happy to reply to messages when I asked for updates etc.

 

Oh I had a terrible experience with MK Motorsport, great contact up until I paid for one that was supposed to be in stock then he dissapeared, then reappeared appologised and said I'd have it the next week, then the following, excuse after excuse then no contact for another week. thankfully money refunded after 6 weeks. Its a real pity as he had other nice looking bits I wanted too buy but just couldnt put myself through the torture again. I just ordered OMS one, ready in 3 weeks so fingers crossed. looks like a nice bit of kit.

 

Oms? More info please and price 👍

Ł800 exchange or Ł980 outright, comes painted and any added brackets for bladed ARB or spring platform removed if running coilovers etc are no extra cost, I'll report back when I get it.

 

Looks bang on mate cheaper aswell

 

Harvey gibbs at scs is well known and respected for making them and has been doing them for years, i will be getting one off him for mine soon. they do vary in quality from different suppliers and I’ve known people to have issues with them from other suppliers. There a very decent company to deal with too and it will be done when they tell you.

 

Yeah thier all ultimately copies of Ahmed bayoo's and harvey did work with him very closely with the dyno work ect

 

Yea i think they do vary a bit though, i know a guy who had one from someone and from memory there was a couple of parts that needed to be notched/scalloped out so the arm’s didn’t touch when they moved, but they wernt done so the arms bashed as they moved and he had to take it all off to get re done ect. Not to mention the reputation people like mk motorsport has for taking money for bits that dont get delivered, or not at least for several months after they are promised

 

lovely looking beam in that pic.

 

I got a Mk beam off Mark in Nov in his group buy on facebook Ł800 un painted +delivery ,also ordered a WRC breather as was good price at time . was delivered few weeks late ok but kept me informed .. I ordered front adjustable arms from him since and came nps . can only say found him ok to deal with .. not got round to fitting it yet though

 

Just out of interest, those people who are running a 6 degree beam, how did you find it changed the feel/behaviour of the car?

 

good question Steve. I would be interested to know too.

 

This article gives a good understanding of what it does and how it changes the charastics of the car http://randbmotorsport.co.uk/shop/Mi...Suspension.pdf

 

With a 6 degree beam the car has less understeer as the toe change on the standard beam pushes the front of the car wide. And when the car oversteers the 6 degree beam makes it much more predictable because the toe and camber change is much less. The standard beam can make the rear quite snappy. All in all the car is much better balanced with a 6 degree beam.

 

Ive never driven a car with one but been speaking to a few people recently who say they make sod all difference and they wouldn’t bother! Literally 5-6 people said the same

 

they can’t be setup properly then or junk bushes and suspension,the touring cars must of put them on for show then if they make no difference 😩😩

 

Bullshit

 

Im just telling what ive been told, i have no experience with them.
Im not going to name names but the people who have supplied and fitted/set them up are very reputable and the owners of the cars are well known on the scene and have had their cars a long time.

 

To be fair I’ve heard people say they make a massive difference and others say not that noticeable.
Always wonder if the people that have good feedback may have had shot spherical bushes prior?
Either way reducing the toe change can only be a good thing.
Had my car on track with standard beam and it was great, although on the road it does tend to suffer from bump steer from the rear

 

I have never bothered fitting one to my car as it's only ever used on the road and I don't think it would make enough difference if any to warrant the cost. Plus I have 2 mates that bought them, one says best thing ever and the other says total waste of money !

With 400+ hp RWD and a good diff and suspension set up I've never had any handling issues on the road !

Would i fit one if I was tranking the car ? Yes is the simple answer.
I belive that it would make a big difference here but I can't drive the car like that on a the road to need a 6 degree beam.

My way way of thinking is, If you have issues with handling and think a beam would improve it then buy one.
If you have no issues but everyone is telling you it will drive so much better with a beam then unless you just like spending money leave it alone.

 

Id say road driving is where you would want one as the bumpy roads here mean the toe angle is always changing on rear.
i find my car quite twitchy on the rear normally but on track where it’s smooth the issue went away and the car handled well.

 

I’ve an Mk one in mine with solid mounts proper diff mount and supra diff. Not used it yet as it’s waiting to go back together. I’ve been told a properly set up beam and good tyres absolutely transforms the cars grip level

 

On the track it won't feel twitchy since there are no bumps. But you still get bad handling because of the beam. Bump steer does not only mean the toe changes on bumps, it will change on any compression and rebound of the spring, so also on cornering. And the bad thing during cornering is that the inside wheel will toe out and the outside wheel will toe in, so both rear wheels are working against the front wheels when trying to rotate the car, and the result is understeer.

In an oversteer situation when you have opposite lock on and when the rear then suddenly grips, the rear wheels are then pointing in the opposite direction of the front wheels, which makes it very easy to loose control and spin the car. And the softer the springs and shocks are, the bigger the movements of the springs will be, and therefore the bigger the toe changes will be on the rear.

 

I was in dry conditions with federal 595 rsr tyres, car is poly bushed all round in beam mounts and diff etc, Koni adjustables and rear toe shims (think we may have said on escos forum).
car felt surprisingly good at coombe really balanced and neutral very slight touch of over steer in the slower corners I’d say but that was easily corrected by adding power which seemed to drag the front back inline.
Tyres were really good never got any where near a slide just a touch too much body roll which is to be expected I guess on an average road suspension set up.

 

Im considering giving the shims a try first now for Ł10 instead of Ł1000

 

I had the car wheel aligned prior and then after the toe shims were installed and they do make a difference.
ended up with the desired toe in after shims were installed
