    If you stand at the rear wheel and look straight down at the ground, does the wheel/tire protrude out past the fender?

    I can see that it does as it gets closer to the bottom of the fender. It appears to stick out at the top but I can never tell if it is or if its just an illusion.

    I can tell you on my car it is even. It does not stick past the fender. IMHO most Ferraris could use a little more width in the rear & front.

    Cool! Looks like you now need to lower the car a bit tho...

    I think that's just an illusion as I had the car off the ground moments earlier. Once I take it for a spin it should settle.

    I think akll 348 could use stiffer springs which would also make lowering easier and safer on the paint.

    It appears that it does just a little. I may get the wheels machined down just a little.

    Mine were the same way, totally normal...

    The original 348 lugs do work though. Many, including myself have used them. I have yet to hear about an issue...

    Regarding the lugs, it depends on the year. My understanding is that '89-'91 348s did not come with the factory spacer that widened the track, so they had short lugs that work fine with the 360 wheels. The '92 and later cars, however, came with a spacer (that needs to get tossed with the 360 wheel conversion) and longer lugs to make up for it. For those cars you need to get new lugs.

    Just to clarify, the later cars didn't come with a separate spacer. The rear wheels were changed to reduce the offset by 25mm -- same effect as a spacer, but not a separate part.

    Thanks, Eric. I got that (apparently erroneous) info from the 348 tech info stuff on this site. I claim no special knowledge, or even an independant thought!

    Yes, it's indoor/outdoor. I've had it down about 3 years and it still looks great. I shampoo it every few months.

    Not from what I was told...If this were the cause, there would different types of 348 wheels and I have never heard. And I don't believe that you would need to make a bolt 25mm longer because of an offset change. I fairly confident that a seperate spacer was used...

    There are two styles of 348 rear wheels. Here's a (not very good) pic of a later model 348 rear wheel (spider or speciale) with the offset indicated: 43.05mm. The earlier cars had a rear wheel offset of 68mm -- unfortunately, I don't have a pic of that type (maybe someone else will post). The wheel with the 43.05mm offset has the extra material added at the inner portion of the hub -- equivalent to where the spacer would go.

    Having said all that, we all know that during the time period in question, Ferrari was not known for consistency in the configurations they pushed out the factory door. So it's entirely possible that some 348s were shipped with actual separate spacers. Also, I suppose it's possible that different configurations were shipped to different parts of the world. All so we'd have something interesting to talk about 15 years later...

    Also, I'm attaching a copy of the famous Ferrari Wheel/Tire spreadsheet which has been passed around here on FChat for a long time. Not sure who made this originally, but to whoever did, thanks. It shows the two styles of 348 rear wheels.

    LOL, I have had a 348 Spider and now have a 348 SS I can tell you that the wheels are different than earlier ones. It's secret knowledge that there are 2 different rear end wheels for the car. Never had any spacers whatsoever. In a way, the spacers are built in to the wheel, although you can't see them. So now go back to your source and tell them that they are misinformed and that you are now the keeper of the flame of knowledge. Feel free to ask us about any of this 348 minutia. :p :D :D

    I know this is an old thread, but I am adding 360 wheels to my 95 Spider and have done a bunch of research about fitment and such using this board. My question is if the rear wheels on the later cars had less offset, does that make the 360 wheels sit more inside the wells then on early 348's? I have seen pics on this board of 348's with 360 wheels that stick out a ton, some that are machined to look right, and others that look fine apparently just "bolted up?" Am I safe to assume that the later cars do not require the machining of the wheels? Not a fan of that process. Thanks.

    in the flesh, the 360 modena wheels is the look on the 348

    Ferrari 512 tr,
    Your 348 that I've seen referenced on this site with the 360 wheels looks amazing. Your car was the inspiration for me to go with the 360's. Did you do any modifications to the wheels? They look "right" on your car. Where did you get the shorter bolts?

    From what I understand the rear width of the suspension of all 348s is the same. Spiders and the SS cars have rear wheels with a different offset. Therefore, 360 wheels should fit the same on all 348s (including your spider).

    I REALLY like the look of the 348 modular wheel made by Speedline that resembles the wheel used on the 512M (this wheel was used on a special edition sold only in the UK)....most look amazing on the 348

    That's kinda what I thought, but then wouldn't that mean that the newer 348 wheels with their different offset would stick out further then he earlier 348. It seems like any year 348 has the same appearance reletive to rear wheel/wheel well spacing.

    This is because many owners have added 25mm spacers on each rear wheel to make their 1992 and earlier 348 look like the Spider and SS wider track. Also, different tire sizes and camera angles make this a difficult thing to judge. The fact is: the Spiders and Serie Speciale cars have an approximately 50mm wider track than the 1992 and earlier cars only because of the offset in the rear wheels.
