    I'm looking to buy a 355. Yesterday I went to see the only one that is for sale near me. this is a 355 GTS with 40,000 kilometers, the presence of the car is impressive and is in very good price, BUT, the car has chassis problems in the past has had some sort of frontal crash and was repaired and not very well. This does not worry me because I can buy it and fix it profitable.

    my big question is the NEXT:
    the most serious that has the chassis is the Sport of the suspension right (above) is ejected from a 4mm chassis. a scary sight but a mechanic understood in these cars has told me that it is normal for the 355 chassis supports booting of the suspension.

    is this true?

    What you have to remember is that for sure the most serious that has the chassis is the Sport of the suspension right (above, no photo....just ABOVE) is ejected or rejected from a 4mm chassis or a 6 mm monkey wrench, but indeed a scary sight of afternoon delight with the skyrockets in flight but a mechanic understood in these cars, those cars....pretty much ALL cars has told me (actually he whispered it in my ear, so I really shouldn't be telling you) that it is normal for the 355 chassis supports booting of the suspension, and re-booting of a laptop. So in a nutshell, the hyperglycemic analogy presented before the board agrees that it is not incorrect with the false assumpion that it is NOT a problem to abstain from the reality or myth of a suspension ghost alleviating the mycetracic echoes of days gone by.

    You need to be a bit more clear in your question.

    Hi, im going to try to explain better.

    The top right front support of the suspension upper pillowball mount has moved down for 4mm and it have a crack all around the support. Not part of the suspension, is just where the suspension fit to the chassis.

    maybe a quick paint pic will help, the green piece is part of the chassis and it has moved down, and the blue line is where it is a round crack

    Hey you monkeys this could actually be a significant issue. You see the 348 and 355 are very close in this area. The 355 ran under many conditions heavier springs. In fact iirc r. shermerhorn was talking about 1500lb springs on the front of 355challenge cars! Anyway the 355c had an extra plate of metal welded to the cars in this exact zone because this are of the car is weak. I ran heavy springs on my 348 and the thing flexed like crazy. Rob and I talked several times about this issue. I did not add the 355C extra plating but instead welded my rollcage to the shocktowers. Boy did that make a huge difference in chassis stiffness. It took me a while just to get used to the way the car handled all over again. Anyway this is a weak area in the cars or highly stressed area in these cars that waxers and polishers will never care about.

    So on to the OP question....I guess an area like this could be welded and plated like the challenge cars to restore the stiffness required. My concern would be making sure the rest of the chassis is square in 3 dimensions. You need this car to be looked at by a proper body shop with the right tools or even a race shop who can check the chassis. If you were building a racecar and tubeframing part of the car then buy it cheap. If you want to make a daily driver watch out. Ferrari repair is not cheap! The metal in the area in question is very thin and while you can physically weld it, welding changes the properties of metal locally. You need to talk to experts. If welding this area is not good then ask them about fortifying the area with the 355 challenge insert which you will probably need to have fabricated because I bet they are no longer available.

    Yes the 355CH front springs were 1500lb stock and option 2000lb both being dual rate split set-up. The CH also had a modified support to sustain this fricken wild italian heavy spring thingy.

    Last time I checked the CH parts..65128500/400 (inserts only), or the complete sides 65128700/800(for LHD) that come with the preceeding inserts are still available in USA....if your car is RHD you will have to check with Eurospares in England

    Bruce...your monkey appears older and wiser than my monkey. Good news from you on those inserts. If I was a 355 guy or even a 348 guy looking for improved performance and not welding in a full cage to the shock towers, I would do the inserts you identified 100% of the time. You just can't have a good predictably handling chassis without it being able to resist yielding. If these parts are truely available I think all owners should put them in. They are of very little weight and stiffness in this area is dramatic! I'd rather have these inserts than a tubi. I'm sure your monster will have these inserts or something home engineered.

    Ha ha

    That monkey looks just like me..really old,wears glasses, has a chain around its' neck...but is muuuuuuuuch wiser..lol

    I always want the chassis to be as rigid as possible...just one less variable when sorting out the cars handling/suspension.
