steering damper
hey guys question got a problem, i have a manx with a problem in the steering, the problem is i think it needs a bigger damper as its only when the
road is uneven that i get the shutter i think its because its so light in the front and the tyre size is 235 this happens any thoughts of wat it could
be and how to fix it p.s the standard damper is new
cheers

I'd start with the basics first.
Jack up the front and put it on stands. Turn the wheels by hand and check everything is running true. The rim could be bent and the tyre out of
round.
If all seems ok try balancing the wheels again (you have balanced them, have'nt you?).
That is a big wheel for a little car and if everything isn't spot on, she's gonna shake.

YIKES
235 is a BIG WIDE tyre to use on the front...
Maybe too BIG...
Original size was 155 so, maybe You have Gone past the Balance of the original front end... and steering box etc...
165 is normal size these days...
ALL that weight of a BIG tyre on a very light front end...
what pressure are You running....??
I wouldn't run any more than 22 PSI on the front..
try 18 PSI ... VW recommended pressure on a beetle..

You hav e a problem with the unsprung weight, if you go for a ride in a big yank tank they ride really well, low unsprung weight contribute's to
this, its the weight of wheel, tyre and the unsprung part of the suspension including the brakes compaired against the weight of the car, the lower
the percentage the less affect this has on the on the ability of the suspension to do its job, in your case you have a very light car with a large
tyre and probably a steel rim, this would resault in a very high unsprung weight, when you hit a bump it has so much mass hanging on the end of the
stub axle it throws the car around and stops the suspension from doing it's job, make's the car unpredictable and ride badly, if you put heavier
shocks on your manx it will even be worse as this will just direct all the energy directly into your light weight car, this is why wheel and tyre
manufactures go to a lot of trouble to make light weight alloy wheels and light weight tyre's, i have a set of three piece 17" rim's with spun
aluminium rim's on my beetle with 45 profile tyre's and this combo work's well with a good ride and excellent handling, a wheel like a centerline
would be the best choice for your buggy as they are spun from aluminium sheet and riveted together resaulting in a very light wheel, a change of
steering damper will not help.

ive got some 6 " wide steelies under the house might get some new tyres for them and see how they go they will be just that lil bit lighter
............. was thinking of weighting down the front alittle i have some alloys but they are 14 " they look good but i cant get tyres for them
anymore to suit the buggy cause even a 60 series tyre will look crap cause of the hight of the car.

Weight what wheel / tyre combo that you run now and compair it to the other set that you are concidering using, take your bath room scales with you to
the tyre place a weigh some of the tyre's that are suitable and get the lightest, mag wheels are no guarentee that they are lighter than steel
wheels, because your car has had the body replaced by a lighter one the unsprung weight has increased even with the standard wheels and it is critical
that you keep it light as posible, down the road concider the center line wheels and on your car would make a noticable difference.
