Default damper angles

hi, i´ve reacently done the first of three tests on my build & at first the examiner saied that it looked good & had no rermarks but after talking to someof the other examiners it was dicided that the front suspension is according to them WORTHLESS
*25x2mm tubes in the front lower wishbones is too weak with pinto motor!
*damper angel must not be greater than 35 deg.
*lower damper bracket too weak & too far from the uppright.
*upper damper bracket should be moved out to get a better angel.
*back damper angel is to big ,damper bracket should be moved out.
i have done everything exactly as in the book but it appears the examiners here dont think its good enough what can i say,heads upp to anyone building in SWEDEN.
i have started on new 25x3mm front lower wishbones but i dont know what or if i could change the angels on the dampers ,could i just move the brackets out? anyone have any sugestions or ideas?
wuold moving the brackets out effect the hight......?
thankfull for any help
samy

What a PITA Samy,is there no justification to appeal the decision and can that be done in Sweden.

How can they say that in their opinion the suspension is not up to the job as many Roadsters are running around in England and other country's.

Moving the pivot points will change ride heights and suspension settings and stronger springs may well be needed to compensate.

If at first you dont succeed,avoid skydiving...

No parachute require to freefall,only if you want to do it twice.

Thanks for the reply Fly, thats exactly what i tried to tell them this is a tried & proven disign made by profesionals... but i need more than that to change there minds, they obviosly dont know what they´re talking about so they go by the rule that more is better.
cheers

The design was done in CAD I presume and FEA of the stresses etc would have all been done and I would think it is possibly over engineered to account for home build and other discrepancies such as weld penetration etc.

Someone more in the know with CAD expierience and an engineering background will be able to help and possibly give you some idea as to what you could present to the tester to persuade them otherwise.

Good Luck.

Also, the overall solution of the suspension is not much different from other seven type cars. It's almost identical to the MK Indy design as far as I know. You could try to find out what suspensions cars that are running around in Sweden have, and appeal the decision based on that information.

Also, there's always a route to take the car to an EU country with easier self build registration rules, then "import" it to your home country. That's the route I'm going to take, I'll take the car to Estonia for the inspection.

it realy sucks & its too bad it has to come to apeals & unnesesary discutions when i know there are hundreds of sevens built & being built in sweden & many of them have the same disign .i think the only way to convince them would be to have some solid tecknicle info.... wich i think is not going to be easy to get.
would be great to hear from other builders in sweden & hear what they have done, i will try to post a thread on locost sweden maybe but as far as the haynes roadster i cant think of anyone that would know more than people on this forum
thanks
samy
