Title: 75 Spring Choices
Post by: GTVeloce on April 04, 2023, 09:38:54 AM
I tried to buy another set of King Springs for my 75 and they are no longer being made! They seem to be making the standard height sets but not the lowered version.

So, does anyone have a set in good condition they are willing to part with? Chasing KARL-05. Or any other suggestions? I know options are available from O/S vendors but would prefer to buy locally and save on cost/freight if possible.

Not having much luck finding king springs anymore sadly so need to look elsewhere.

What are others using in the back of their 75? This is a road car so not looking for track springs but lower and stiffer (but not crazy stiff) would be preferred. I am currently running the standard height King spring at the rear and the spring rate is ok but the height isn't and I can't cut these springs.

I have Eibach springs in the rear of my 75.  Lowered the rear 15mm < 20mm.

Or have the King spring free length reset?

GT Veloce,

What is the free height of the KARL-05 ?

I may have a set that will work.

Thanks for the responses. Another forum member sent me a link to the Eibachs through EB Spares (which incidentally are cheaper than through the Eibach site). I have emailed Eibach for the spring rates to see how they compare. As reference, the King Springs KARL-05 are 95-155lbs (progressive rate spring). I always found this quite good for a road car. I'm sure a dedicated track car would want firmer but the roads in Eastern Melbourne are rubbish!

MD - I'm not sure what the free length of KARL-05 are. I have a set but they are installed in my GTV. I'd prefer not to remove them unless I have to.

I have also found another source from the Netherlands. Never heard of this supplier but lots of Alfas that way!

Also a progressive spring - dual rate. I asked for the spring rate and was given 27N/mm which I am guessing is the firmer setting. I did some calculation and it came out very similar to the KARL-05 firmer rate.

I have just measured a spare set  of KARL 05 I have that measure a free height of 400mm. Send me a PM if they are of any interest to you.
