Hi is the Mk sprint allowed in to any of the race championships that we race in.
MMmm!
Think someone is getting their companies mixed up,as the sprint is made by Martin (MK engineering),this subject is to to with MK sportscars I
thought??
Perhaps the slagging off other companies first before you realise all the facts is ok with some but it smacks of petty bitching to me,not very
profesional is it.
I have'nt seen the car or wishbones so i'll refrain from commenting!!perhaps others shouldn't shoot from the hip too!
Once I've finished a project why do I start another?

if the above last few statements are correct and the wishbones aren't actually mk items and therefore non of this is actually mk sportscars
fault then i do hope procomp will be issuing a full appology to mk.
however if the above last few statements turn out to be incorrect then please feel free to ignore this post 
built a car, built a home, had a family. lost the family, lost the home, still got the car.

Wooooaa!!! there chaps, this appears to be getting well off topic. In terms of moving the bracket in question, no mountings have been moved, the
bottom ones have been widened on one mount to allow the bottom wishbones to fit in. The picture in question was me trying to offer up a old pair of
Luego ones that I got off ebay. The suspension geometry has not altered since it left the MK factory on 30/03/06, It also has Mk Locost wishbones
fitted.
Back to my original point, I was trying to acertain why my suspension has zero castor and if it is correct. Any research that I have found states
that I need some incorporated castor, whereas MK say I dont. The reason why I need to sort it out now is because you cannot use adjustable top
wishbones in the 750mc race series.
This then leaves me with two options...
1) My Locost race car will not need the castor - I leave everything as it is
2)I change the top wishbones to accomodate the castor.
The only thing that makes me think it might be an inbuilt design issue is when I hear of other people having difficulty with self centering on their
cars (a quirk of poorly set up castor).
And yes I was told on the phone that none of the Locost race cars have the castor

I dont think anyone has thought that you were causing a fuss! someone else has done that!
Does seem strange that no castor is built in though.
I would think you might be as well clarifying things with Martin himself at MK engineering who was responsible for building some of the early cars for
Ron Champion.He will know if the castor was built in or not,althogh obviously Martin does not run MK sportcars now.
Once I've finished a project why do I start another?

Right, this is going in a tangent. Back to my original point. As I have said this is a 750mc Locost race car.
Initially I had a set of Luego bones and the 'rear' bottom wishbones mounts were replaced with wider ones that would accomodate the Luego
bones.
The front mount has NOT been moved and has stayed in the same position, the rear mount has been replaced with a wider one that would allow the luego
bones to fit in. Therefore the suspension geometry has remained EXACTLY the same and not altered from how it was on day one.
Fitted now is a set of MK locost wishbones utilising 3 of the original mounts and one wider one (to accomodate the Luego ones), as you can see that
the geometry remains identical.
Oh, and just if it aint been clear here is my car sat with my MK bones

Be fair charlie, I have only put this post to find out what I need to do now. I have in no way slagged MK off and since you wish to go through my
previous posts you will be able to see that I have defended MK in the past when people have been asking 'why they do not answer the
phone'
The be-all and end-all of this post is cause I am not sure who is right. At the end of the day, I am building a race car and it is important for me
to get the handling right. I have ZERO experience of setting race cars up, but I have been told mine is wrong by several sources. You need to
remember that before I put this post up I called MK and told them the problems I had, I was not convinced by their answer hence my original post.
Look, if people want to take it the wrong way and see it as MK baiting then you have too much time on your hands. I have no time for slagging folk
off, as I have a race car to build in time for March.
As i keep stating all I want to know (as I am not convinced by my original reply) does my 750mc MK locost chassis need any castor? If it doesnt then
there is no problem and we all go back to work. But if it does then I need to change the top wishbone

Hi right my last say on this.
1. we now know that he dose have the correct wishbones on the car and still has ZERO castor as MK said it should have.
2. All of the chassis from other manufacturers for the locost 750mc championship DO have castor on them.
3. The 750mc actualy state in the regs that the top brackets are allowed to be moved from the book dims to achive the desired castor . And currently
all of the cars running in the championship are running LEGAL wishbones.
Charlie (snoopy) You say that i have been slaging Mk and martin kenan off in previous posts. But actually all i have done is to disscuss on a
discusion forum what is actualy commonly known. IE that the INDY has lets just say not verry good rear geometry. This is accepted by martin as he
offers a service to re jig the backend to correct the problems and HATS OFF to him for admitting and offering to do this.
Lets hope that MK sports cars offer the same deal with the top wishbones for thier locost kits. Unless they are going to openly say that ZERO castor
is preferable to having castor.
Regarding my comments about the MK sprint when i and other didnt think the chassis was verry clever we were all told that the pics that we were
looking at were of a prototype chassis and that the production version was going to be fully computrer designed to give better geo and more strenght
in the chassis and since then i have made no further comments. Has the chassis beeen changed for production from the prototype one ?.
cheers matt
PS the 750mc already allowed the use of oval tubing in the locost championship as we were doing that since year 2000.
And the only wishbones that were bending were the luego ones whitch they strenghtend up and the MK ones which are still bending even the oval ones
such as the ones fitted onto james oddonels car supplied earlier this year.
PPS paul aspden is no longer in buissnes setting cars up although he dose still do some grp work for kit cars.

I just found this thread.....incredible!
It's a very brave man who drives a car with NO caster. How does it self center? Shopping trolley geometry! You'd get big arms pretty
quick!
And, the winning cars in the next 750mc Locost championship will probably be Procomp prepared, if not supplied. They will handle in a markedly
different way to everything else, ....except mine!
So, if you want up-to-date handling and grip, go to Procomp, accept what Matt does and don't ask questions about specifics, because they
won't be answered directly. 
Cheers,
Syd.

I think its about time I left this forum as I am getting more than a bit pi@@ed off with pratts slagging everyone off.
Some helpful forum this is,one person is after some help to correct a problem and idiots who should know better jump in slagging everyone off!
I for one will never deal with Procomp after the pathetic comments that have come out here again.
I thought he was a professional?
As for Aussie Sydney Bridge,who the hell opened his cage?Syd,everytime some crap starts flying you are somewhere near it,I wonder why??PS. I seem to
remember the farce a year or so back about some accident damaged wishbones a certain nameless person used to con money with,you really do seem a nasty
peice of work.
Thats it ,I'm off this forum..it's being spoilt by petty troublemakers,what a shame....
Once I've finished a project why do I start another?

I couldnt agree more dean, it's a shame really, there are some really decent people on this forum and some very good information, I allways try
and reply or post in an adult manner, some of the answers I have recieved have sounded like they have come from a bunch of primary school kids!!

funny really i kinda knew where this thread was going to head as soon as i saw it, couple of two footed tackles and we are off again.
my opinion on manufacturuers areas on this site for what its worth ........ they should read the posts in there area and answer the questions
themselves,if they cant do that then they should ask chrisw to remove them from the site.

Yes, you DO need castor.
About 7 degrees with Cortina uprights. That's what seems to be common in most of the intelligent world.
Sierra uprights can tolerate some more, depending on how heavy you can cope with your steering being.
Cheers,
Syd.

No surprise you're an MK avid supporter. You've built one!
It appears that MK race wishbones are still in need of some attention, as are the originals which DO fail in racing without getting anywhere near an
accident.
After that 'fiasco', some manufacturers actually strengthened up their designs, so it had some positive results.
When the kit industry here gets the same engineering oversight that is mandatory in Aus, a number of manufacturers will disappear, or be forced to
make some fairly big changes to their products.
I don't want the Aus system, but unless the manufacturers design their products properly, then I see it as a necessity.
Cheers,
Syd.

Well it looks like I might have to make some wishbones that will incorporate castor?
What about using valve springs to get the car to self centre? I have seen in old posts folk have done that, will that sort it out for me?
Finally thanks for some useful advice chaps

hi mate
the valve springs is a trick to get your car to self centre
its not dangerous if done properly
it just shouldnt be needed
so I wouldnt Id do it the proper way

As Matt at Procomp is setting the car up for you, why not take some of his advice? No doubt he knows and has probably told you exactly what is
required in order to get it to self centre and exactly how much castor is needed. If not, take it somewhere else to be set up or better still, get
some advice from Syd Bridge and do it yourself

I'm with DeanC and Mad Dave on this one I'm afraid.
It seems to me that certain posters have an adgenda with MK products, both MK sportscars and MK engineering and they're clutching at any sort of
tenuous link to put the boot in.
I think manufacturers should stay out of this sort of discussion because whatever you post, well intentioned or not, looks like sour grapes.
If your advertising consists of bad mouthing the opposition then you're in for dissapointment.
I'd include ex manufacturers such as Keith (Syd) in this too.
