Help! Speedline 328 Wheels on 308

Almost sounds like they are Speedlines for a 88.5 or 89 328 (convex wheels), where the difference in offset would push the rubber up against the spring. They may be just right for the later model 328, but not the earlier ones (and the 308).

 

Might be they gave you ABS offset wheels (either 328 or Mondial) where you need the non ABS offsets for the 308. This ABS offset would sit the wheels way deeper into the car and perhaps rub on the spring.

Speedline is the Ferrari wheel OEM.

You should send them back.

edit: mule beat my post by one minute

 

I had the same problem, I bought a set of O.Z. wheels that a guy had on his NON ABS 328. He said that they would bolt right up. Wrong. The fronts fit no problem, but the rears needed to be spaced out 1.5 or so inches. I had custome spacers builts and now my rear wheels poke out a bit. I also get rub on some G-outs. I am waiting to get QA-1 shocks before I address this situation.

 

It might be better to get 328 or 16" qv wheels with the proper offsets. I think you might be happier in the long run rather than futz with spacers. Ask me how I know.

Quasi -- When you say --"They look exactly like 328 wheels to me" -- which ones 328 abs or 328 non-abs? What are the wheel (width x diameter) values? If you can also measure/determine the wheel offsets I think that would be good information for you to have regardless of what you do next (i.e., using or reselling). Just takes a ruler and a flat floor -- give a shout if you need help with that.

For larger thicknesses (more than about 1 inch) you'll need to use what is essentially a "bolted adapter" (e.g., a Hill Eng Type 2 Spacer as shown on this 348), but it's still not clear to me what you are trying to do (wider wheels on a 308, or big offset vs little offset required).

I also have done the spacer thing. It is a lot of extra stuff (all new bolts, spacers, possible re-aligning suspension (if you want to do it right) and adds a level of unneccesary complexity. As we assuming this is a 16" cosmetic upgrade and these are the convex 328/Mondial ABS wheels you have, they are not as correct or attractive as the concave wheels which bolt right up as the originals to your beautiful 308. I think once you see them on your car versus what a concave set look like, you will be glad you got the other. So will any knowledgable potential buyer down the road.
While Lord knows I am not an originality purist, but I am a simplicity orientd guy. I took mine off. I think you might be happier in the long term with a set on correct offset wheels keeping things very simple. If he is a reputable dealer as you say, he'll understand that these are not the correct wheels for your car and take them back.
That all said, if you really like the convex look, Steve is right about the bolt on adapters. The offset difference is possibly so large that you will need the kind that themselves bolt onto the hub. Depending on what your final offset is, it is very wise to recheck the suspension alignment - at least this was my experience.
Anyway, it's just a car (although a nice one) and you do what makes you happy.
best wishes and enjoy

Here are the measurements for the stock 328 88.5 onward rear wheel is 1.85" from the back of the mounting pad to the front of the rim and for the pre-ABS cars it is about 3.7" from the back of the mounting pad to the front of the rim.

George, it sounds like maybe you have the wrong year 328 wheels. I personally would not go with spacers because I think that the concave wheels look a little better so I would try to get a set of those first. If not, put the concave wheels on there with spacers/bolted adapter. In effect, it's probably 6/half dozen.

Is Tica still liking the car?

 

So Quasi & Tica are the ones from the Forza 308 article? very cool! Too bad about the 328 wheels. With all the 308, 328, & 348s out there needing wheels I sure don't understand the limited selection & high prices we have to pay for aftermarket. Ronal seems like the only good deal.

ps thanks for Forza story, bought my 308 a couple months after I read it.

 

Am sure they are, but how much do they weigh as compared to stock? Have heard they are much heavier and adding unsprung (and rotating) mass is a real performance killer. Especially on cars like a 308 that is already underpowered IMHO

While not cheap, i guess you get what you give so i use Kinesis K27, 17-inch by 8 front, 9 rear. VERY durable, within a pound of STOCK wheels, but i GAINED 1-inch of rubber all around and NO SPACERS needed and they fit perfectly (and i DO mean PERFECTLY).

PS: i would not want to track my car as much as i do with spacers in there, but hey, that's me and Mr. AN-L Retentive Safety speaking.

my poor attempt at photochopping, if anyone cares to correctly photochop some 17 inch r41 onto a red 308 I'd appreciate it. Someone said I made them look more like 19-20inch size. For less that a 1K to your door, I'm tempted!

They're only available in one width, unfortunately. You have to go to their LZ wheels (they look good too) to get proper width combination and offset.

 

I've seen 288 GTO replica wheels in 17" with a center cap that resembles the center lock lug that look great on a 308. Scan thru the "let's see the 308s" thread. There is a black 308 in the thread with them on and they look great. Try T. Rutlands to source them or possibly Nick's Forza.

Good luck,
John

Edit: Page 17, post 327 of the 308 thread shows a good shot of the 288 wheels on a black 308. A few pages later they are pictured on a red 308. I think you can get them from Speedline or Compomotive.

 

I WISH!!! I like that look much better on our cars than the Speedline/Compomotive with "hidden" lug bolts.
