Front Suspension Springs

[d068795n]

Gentlemen, can a member with a 2000cc Ford Pinto engine in a Triumph front suspension roadster SWB Mk2 advise me of a pundage rating for the front springs. At the moment mine are of an unknown rating and far to stiff. Thanks all

Re: Front Suspension Springs

If your car is on the road simply take it to a local weighbridge and speak nicely to the operator
You want the front and rear weights
Then calculate the appropriate spring rates

1 Hz (60 cycles per minute) - is ok for a luxury saloon
2 Hz - 120 cycles per minute is about as high as you want to go with a road car

If its any help a hybrid with a Triumph 6 cyl engine rides quite nice on Mk1,2 or3 Spitfire standard springs not shortened
they are the softest available regular springs to fit a Triumph .
