Yes, custom front bumper. Here's a whole thread on the car: http://www.ferrarichat.com/forum/showthread.php?t=235944
Well, the 348 is a road car. If I want to go on the track, I use my racer. For road duties, the 360 wheels seem to be just fine. Haven't seemed to have an issue with them at all or any related problems. And handling is improved with them too. Like I said, what you say, is probably correct, but the 348 is not a track car, so how it would behave on the track is irrelevant.
Mark, I have the opportunity to get a set of those wheels, but another 348 owner has said they are two big for the rear. What's the rear fitting like?
Would that not only be the case if you are planning on swapping the rims and leave it at that. If you re-align and re-corner balance the suspension I don't see any problems.
Have these on mine with 285 30 18 rear tyres which do stick out the arches alittle..thinking of going to 275 35 18
Here are a few more pics. to help you decide. I think it looks great. Hey Pap, I just had the major done, the bearings need to be changed every 30hrs or 30 miles which comes first.

Are all 360 rims the same size from year to year? I really like your yellow spider with the modena rims, what size tires do you have?, they look well proportioned on your car. I know you said that you haven't had any issues with them, does that mean no tire rub also? Thanks.
Thanks guys, No tire rub or anything. fronts are 225/40/18 rears are 275/35/18 depending on the year of your car, you may have to buy shorter wheel bolts for the rears. same length as the fronts.
Hi, firstly you do not have to take my advice. And I really apologize if I have stepped on somebody's feet here. I am talking from experience and not something I make up to be interesting. If you run the car mostly on highways at 55 mph and only do a couple of miles every year- you will be fine. Not a lot of strain on the components then. If you want 360 wheels just do it. I try to explain why I would not do it. 1. Bigger wheels with wrong ET give the wheel bearings a hard time. If you like changing those more often , well no problem. 2. The bigger size of the rim and the tire creates a bigger force on the rolling resistance, giving engine and shafts harder work. The result is lower top speed and less acceleration. I would think the 348 is about 1,5 sec slower to 100 mph. And top speed goes a little down too. 3. The heavier tires and rims (360 wheels weigh more than 348 wheels) are going to make the suspension less responsive, thus creating suspension that does not cope with irregularities on the road as good as the stock set up. This is just how it is. Try put bigger wheels on your Merc, Bimmer or Mazda you will understand. 4. The car suspension geometry was created for the stock wheels. Going taller will mess that up. 5. Those rear wheels are going to throw stones on your rear bumper.... to wide. If you live where it is dry or are friends with a painter, well no problem. 6. Modern wheels on a classic car. Why? Well why not go and buy a 360 then. Then you get the car that suits the wheels. There are less and less good ones of the 348s. But this is down to taste and people do what they like. 7. For me driving a Ferrari is the interaction between the parts. The feeling of a symphony and art on the move. I would put the 360 wheel money on parts that increase and better this feeling (like new suspension bits (for instance aftermarket coil-overs) that removes the horrible under steering from the 348. I think the 348 would look good with the stock rims in dark grey or maybe even gold. That's different, but you still get the handling and balance of the car intact. But, do what you want. I do think a lot of these cars look better with aftermarket wheels - REALLY! and as ztunelover wrote; if you re-align and re-corner balance the suspension the car is going to feel a whole lot better than just bolting it on. I think that is the key. Think before you act and there is no such thing as a bolt on. Put those 360 wheels on, go to a good garage and tinker with caster, camber, toe in etc. And you will have your look on the car but also find some of the magic in the suspension back that you have lost. Good luck and take my advice not as criticism, but a possibility to see two sides of wheel swapping. It is like swapping a wife you never really know what you are going to get, but it is a new wife right!-) Maybe doing the 360 wheels are a good thing! And by the way. I have four 360 wheels with tires in excellent condition, with the correct spacers for putting them on a 348 for sale. So if you still want to do it after my rambling, I have the goods!-) I am not exactly a good seller am I?
#3 I do not believe that 360 wheels and tires weigh more that 338 wheels and tires especially the rear wheel on the SS or late model 348...
heres the deal... forces of inertia do not know if they are spinning aluminum or rubber? larger diameter wheel = less tire. ...its physics you cant change it ... so if the overall weight is the same it should make no difference on the suspension components.
No no, I was just hoping you would explain as you did in this post. I was not trying to discredit you. I am still learning so I was just curious. I don't have a Ferrari...yet. I was considering 360 wheels on the 348, but me being me I have yet to reach any concrete decision on whether I like the look. It looks great in pics and reality, but I am not certain how practical it would be to drive it a lot with the rear bumper sloping in. 355 challenges seem like a good choice to me though. I think that wasn't the best time for that advert there.
Well yes and no. If the wheel is wider - it treads the tarmac at a wider patch lets say difference betwen a 255 and a 325 mm, and therefore more resistance. Also the further out the heavy stuff is out in the diameter, the more weigh arm (aka centrifugal force) gets in to play. Heavy bits in the center of the hub is not so stressful on the bearings as further out. Why do you think manufactures really try to keep the weight down on suspension components and light alloy wheels for fun? More weight on suspension slower response. Think heavyweights fighter and flyweight. ...But believe what you want. There is more but I can not be bothered. This is my last post on the subject.
Wait so you mean using spacers and wider wheels whose offset gives it a spacer effect will still put excessive stress on the wheel bearings regardless of the weight difference? I mean lets say for a second we have the standard 348 wheels which weigh xx pounds, and then we get the 355 challenge wheels which with tires on both probably weigh very similar xx pounds. The challenge wheels effectively space out +16mm if I am not mistaken. So the extra offset will hurt the wheel bearings more? Would a similar effect happen with 16mm spacers? Thanks for sharing this stuff by the way. Regards, Krish
I've been following this thread for a while. For the OP. You can bolt 360 wheels to your 348 with some needed modification to the rear wheels and a chassis re-alighnment. Which includes setting the ridehieght, adjusting the rear camber, and resetting the toe in front and rear. With proper rear wheel offset and chassis adjustments, Your car will have predictable neutral handling, given your tires are fresh with proper pressures. First, you must machine 19mm off the rear hub of the 360 wheel to regain the proper offset. Period. It makes the 348's already too high ride height even more 4x4 looking. Maching the rear 360 wheel hubs does not weaken the wheel. Second, order 10 new shorter bolts to install your modded rear 360 wheels. Third, Lower your 348 25mm to get the correct ride hieght. 348's sit too high from the factory. I think they did that to lessen the chance of knocking off the front lip. A 355 front bumper has more front lower clearance than a 348 front bumper. That is why I switched, usung a real European model bumper without those ugly USA side marker lights. Lower better handling car with better front ground clearance, hmmmm. Fourth, set the rear camber according to your driving style, ie; how your rear tires wear. So many 348 guys are always complaining about wearing the inner part of the tire tread off. Well, remove camber until you get even wear. It doesn't get any easier. You'll be even more satisfied that now the rearend of the car doesn't come around on you with out warning. 360 wheels are the lightest compared to 348 and 355 street wheels. Front Rear w/tires F R 348 28.6 32 51 56 355 22.2 24.4 ? 52 360 20.6 23.8 42 52 The "horrible" handling as described is corrected with simple chassis adjustments without spending a dime. Well, maybe a case of your mechanics favorite beverage if you can't DIY. 360 wheels will NEVER need "spacers" to install them on a 348. Here are some pics at different levels. Also, a rear quarter look showing the rear wheel inside the arch and the corrected camber.
