Hey gents. How much shorter are alfasud springs vs spint. In SA we have got access to Eibach, but not Spax which seems to b popular. Any advisable options to lower the car 30 to 35mm? Thanks

Oh ! Thats a big subject really !!!

You can use the springs from either a sud or a sprint or a 33 as they are all interchangable, except the 33's that came with the cone type coilovers and 3 bolts on top instead of 4 !

Problem is, there are all sorts of different coilovers for those cars in terms of hight and stiffness !

Then your sud should have the deeper dishes , which situate the car lower with a relatively higher suspension.

So, if you want to lower your car at front at about 35mm, then you should buy a lowering kit for a 33 ( H&R works perfectly for me and some other friends ) and you should change your dishes to 33 ones otherwise you will end up lowering the car much more than what you are after !

H&R springs I bought from Alfa Romeo Shop - Tuning, Styling, Fanartikel und Modellautos - Alfa Romeo 33 Tuning & Styling

Very happy with their service and prices. Done business with them a few times in the past ;)

Thank u for the response. Would the H&R be a direct fit? From what i understand even though they 35mm it might be even lower due to the car being an Alfasud?

Thats exactly right !

The H&R's , which are a direct fit, are ment for a 33 which has higher dishes on the front shock absorbers.

Think about it this way: If you take stock 33 springs and stock Sud springs, the Sud's will be higher and stiffer.
So if you put stock 33 springs on stock Sud shock absrorbers, the car will lower about 25mm but it will be softer - which is not good for the handling of the Sud.
Moreover if you put performance lowering springs of the 33 - like the H&R's on the stock shock absorbers of the Sud and keeping the lower deeper dishes of the Sud, you will end up with a stiffer progressive setup , but the car will lower another 35 mm - total of almost 60mm ! - which will look ridiculous as the rear end of the car will look like an offroader !

So , in other words, the best setup is:
H&R's lowering kit of the 33 on stock sud shock absorbers, but with the lower dishes of the 33 instead of the Sud, so the spring will sit a bit higher and help you keep the balance right ;)

Hope this helps

Lol! I get what u sayin, it makes perfect sense. At this point do no want to fiddle around much. Justsud springs have direct alfasud springs (correct fit), so that could be an option. Are Justsud springs advisable option?
