1971 500L. I'm going to rebuild the front spring and reverse and re-arch the main leaf to lower it a bit. The front spring is very stiff so, even with new shocks, the car sort of skips around on rough roads. Can I remove one leaf to soften it and make the suspension actually work rather than just bouncing around? If so. which leaf? The rear springs are softer and the suspension absorbs bumps as I think it should.
Thanks,
Ken
 
As you are probably aware, there is very little weight on the front end which probably results in the skipping that you describe.

By the nature of lowering the front suspension the ride will become harder.

Personally I would be a little wary of removing or softening spring leaves - that sounds like a brave move - that's not to say it couldn't be done though......

Sorry - I've been a bit quiet lately.

If you want to lower the car front of the car you can fit a reverse eye front spring, but as suggested, the ride does get harsher and occassionally there will be problems with tyre rubbing. Most of the retailers that sell parts for these cars also stock this type of spring as a 'performance/handling option'.

If you remove a leaf you will weaken the overall rigidity of the spring and it may collapse/invert. This won't be good and I wouldn't recommend it :(

Most of the sedan front springs had 5 leaves with the exception of Australian cars that had 6 as pointed out by Damon500 on this forum some time ago. So in an Oz car you could probably remove a leaf fairly safely, though which one I don't know. As your flag suggests Italian residency, this isn't an option.

Another alternative would be to convert the front suspension to coils. Kits are available, though expensive. You may then have the option of fitting softer spring rates. I've attached a photo.

Finally, rather than removing a leaf, as oops suggested above you could put some weight in the front to damp some of the rebound, the downside being an even slower car. You then need to build yourself a more powerful engine etc. etc. (y)

Let us know what you decide to do,

Chris
