Purchased a 6 degree beam for my 3 door a few months back and recently got round to fitting it but ran into a problems. When mounting the beam up using solid bushes it hits the floor pans next to the handbrake cable brackets. To get the beam up to the height it needs to be to bolt the diff mount up means it pushes the floor pans up quite a lot. It’s where the adjusting box sections come out of the front of the beam. The beam is mk motorsport and solid bushes all supplied through anembo. Has anyone else experienced this? Currently in talks with anembo and they think it could be the solid bushes causing the problem regards to height of the beam at the bush mounting area. Any help appreciated
Had a similar problem with powerflex bushes, the beam just touched a tiny bit but would have transmitted a load of road noise so I made some spacers at work.
Had to also make an extension for the centre tube as I didn't have enough stainless to make new longer ones.
Thanks @Mark V8 . Mine is a little more than just touching it literally pushes the floor pans up by about 1/2 inch! I’m worried I’m going to have to space the beam down a lot to make it fit but I’m sure that that’s going to alter the geo of the whole beam and arms dramatically. Anembo say they are going to design and make some new bushes in the new year but what I really want to know is what size of bush did mk design the beam to, was it to a standard oe size bush or a a solid ally bush of some kind. There must be a measurement for size of bush that was used originally when jogging it ip? Also there is a question as to whether the lip around the locating hole should be ground off when using the solid bushes?
What ever you do don’t ask him. As he will go right off on one about being an amazing engineer who builds rally and f1 bits. Then tell you how many he has sold and how no one has ever had a problem with any of his bits. Then that you must not know how to fit them properly lol. He is an utter cock.
I’ve one of his beams in mine. I fitted it ages ago don’t think I had any issues. Mines on solid mounts but there not his mounts.
Ahhh interesting subject and i had / have exactly the same issue on my 3dr cossie.
so i fitted the MK beam (i bought it secondhand) with new black series powerflex beam bushes back in the summer and bam the box section part of the beam was hard up on the floor. I compared my new bushes with an older set of powerflex bushes and the dimensions have changed. The overall size is the same but with less meat at the top of the bush so the beam sits higher up on the bush and thus against the floor just like your solid bushes.. I have fitted my old style black series polybushes that i had in my standard beam and now it clears but is still very close. I presume the design changed slightly to sit the standard beam higher up keeping things more aligned on a lowered car, but that's a guess and really i have no idea.. I am also concerned that it still might touch and cause vibration through the floor requiring a further bit of spacing. Will find out when i get to drive it but currently waiting for a set of trailing arms to be modded. My advice to anyone else thinking to use this MK beam on a 3dr cossie is dont.
Thanks for the input @Mad_Mat knowing what I know now and the problems I’ve had with this beam from day one I would never buy another mk beam but from somewhere with a better reputation and you can actually speak to when a problem arrises. The conclusion is I’m currently waiting for an update from anembo but I feel they are stuck for a solution and we all know that altering the height of that beam at the front a lot could dramatically alter the geo of the arms so much that the correct adjustment needed in terms of camber / toe etc may not be attainable. Currently 1800 quid out of pocket with a beam that doesn’t fit, poor powder coating the first time when I got it back and having to get it done again and the bushes that could end up being paper weights.
Russ i feel your frustration. Long story short i bought my MK beam secondhand but unused.
I went for it because it was the supra diff version and i was running a supra diff with fitting kit in a standard beam. So happy days i thought nice upgrade...
Of course I got it off ebay & a fair price to.... Now it was sold as 2wd and muggins here being a trusting fellow took the guy at his word. The key thing I didn't know is theres a difference between 2wd and 4wd trailing arms with the hub mountings being different thicknesses. I looked at it and thought that looks great and handed over my hard earned. You guessed it my new beam had one saph 2wd arm and one saph 4wd arm. Most peculiar and no major issue except this was not apparent until I'd spent 3 days at a mates garage fitting it all up with new coilovers all round. Messing about with new/old style beam bushes in and out to get floor clearance. Eventually get wheels on and of course 4wd side is sticking out.. head scratch wtf and the penny dropped... maybe not such a fair price after all.
low loaded back to my house. Stick in garage shut door and sulked for a bit. That was June. Now I have been waiting the thick end of 6 months for Anembo to convert a fresh pair of arms for me. I have my fingers toes and eyes crossed that it all lines up okay with the new trailing arms and the geo is good.
Trying to make improvements to the car gets so frustrating when it bites you in the arse. I heard good things about the 6 degree beams and I am hoping the car will drive better than ever when done but its way off plan so far.
Mark V8 - Love that spacer kit. If you do anymore spacer sets for the beam bushes i would be happy to purchase some from you.

That is actually not correct. The 2wd (sapph) and 4wd arms are exactly the same, finis code 5029060 for the RH and 5029061 for the LH. The ones with a thicker hub mounting surface are from a Granada mk3 (giving the wider rear track). Besides the wider track the camber on the Granada arms is also more negative, because of the higher ride height of the Granada.

Thanks. Well you live and learn... Someone told me that was the case but i defer to your knowledge here Marc.
if anyone needs a left rear arm with wider track for an MK beam i will have one available shortly.

U do realise mk witch is mark doesnt make the beams now hasn't for a couple years he sold the rights to the guy above a anembo
That’s what I thought but Ben at anembo said mk still make the beams and only the beams for them now they do everything else themselves!? I really don’t know what to make of all this to be honest. Have spoken to Ben today they are making new solid bushes in the new year and for now supplying me with poly bushes to fit it up temp for now, will see what the clearance is like then. I will update when I have the beam and poly bushes and fitted it up. I’m not entirely sure this is going to cure it but will see…….
I cannot remember if I had to mod the solid mounts on my 205? I think I had to remove a sleeve but that was more to do with my car mounts???? It was long ago now.
I’ve an mk beam I must admit it fitted fine if memory serves me right. MSD solid mounts. I’ll see if it’s good when it’s tracked up lol. But after the complete Fook up of a front set up he sent me I’d have no confidence in his work now. Imagine buying some of that twats motorbike parts lol you would be worried about dying every time you went out
