dodgy front end bouncy bits

hi

anyone recommend a spring that would be suitable for this application, I was thinking of a Capri leaf spring but it has to fit down 2 inch wide chassis rails which isn't very wide really but that’s what I've got for a chassis. The engine is the 2.8 with a type 9, it got glassfiber bodywork but am not really too sure of the axle weight so was thinking of making the front adjustable by using a large screw to push down on the spring to raise or lower it. probably a naff idea but it just popped into me head...

any thoughts?

oh and I know there's no dampers, they are not needed in the states...I was going to use hi-tech friction plate ones cos I like to live dangerously

MG Midget?

Though what you really seem to need is a quarter eliptic spring from an early Austin Healy Sprite.
as in (b) in this picture

cheers

yeah the midge one might work except its only rated for the weight of the back of a tiny car it rather than the front end and I have a heavy v6 in there. I have plenty of length down the chassis rail to take a full spring though

You may be right, but it does need to take 2 fat blokes and luggage from that end of the car - say 300kg
2.8 is around that isn't it?

you may have a point, at a guess the 2.8 was about 30-40kg more than the pinto and the engine is quite a bit back from the wheels and it would certinly be easier to mount the half springs to the end of the rails than inside them, good call

MK2 Jaguar use 1/4 eliptic rear springs, you could remove leaves to get the spring rate right.
