Sold Custom 18" Speedline Alessio Wheels for Ferrari 348, F355, or Testarossa

I'm selling a custom set of 18” Speedline Alessio Wheels with larger lips for aggressive fitment. These were originally installed on an auto industry entrepreneur and wheel executive’s F355 that was lowered on air bags. I purchased this set from another well know auto industry entrepreneur, but never installed them on my F355.

The Front tires are Michelin Pilot Sport 4 - 215/40 R18 and Rears are Michelin Pilot Sport 4S - 245/35 ZR18 with the earliest date code of 44/17 and the latest of 31/19. They still have plenty of tread and can be driven as is. I believe they will also fit the 348 and Testarossa, but please do your own due diligence.

The front lips are approximately 1.75” and the rear lips are approximately 3.25”. These wheels are not for everyone and could easily be re-lipped to be less aggressive. There are some minor marks on the wheel faces, some marks on the lips, and marks on the inside of the wheels as they are used.

I’m asking $3,500, which is the lowest price I’ve seen Speedlines listed for. Located in Orange County, CA, but I can ship them at the buyer’s expense.

I took one of the rear wheels to UPS to get shipping quotes. It weighed 49 lbs and 5.2 ounces. The fronts should be about 5 lbs lighter. Shipping across the country to Mass. with $3,500 worth of insurance was about $575.

I believe they are 8.5" and 10" wide. I'll measure the wheels later.

 

I don't see the Speedline etchings, so they must be generic lips. I found another photo that Mark Arcenal posted of the wheels on his car. That car and these wheels were sold to Bryan of Period Correct and then @Tarek307 purchased and sold the car. I purchased the wheels from Bryan separately.

I measured the wheels tonight and found that they are 18 x 8.5" in the front and 18 x 10.5" in the rear. The front backspacing is approximately 5.25" and plugging that into online calculators, you get around +12 or +13 offset. The rear backspacing is about 6.75/6.8" and when plugged into online calculators, you get around +26 offset. Hopefully this is helpful and accurate. I found additional photos showing the fitment on his former F355 that was stock bodied.

Agreed. Comparing the fitment photos (front especially) to the offset calculator doesn't make sense. Buy these and you can re-lip to any custom offset you want.

 

I'll measure again today. I measured the front at +21/22 and the rear at +39/40 the other night.

 

Here are my final measurements, which are as accurate as I can get:

Front Wheel Specs: 18" x 8.5" +25 Offset

Rear Wheel Specs: 18" x 10.5" +40.5 Offset

Hopefully that helps your decision.

 

Thank you! I want someone to use them on their car instead of having them sit around collecting dust. They're one of my favorite wheels, but I will be selling my car with the stock wheels in the future.

I understand. These wheels are rare enough that I purchased them intending to re-lip them to be flush. I think they're priced fairly and I'm negotiable if you decide to go that route.

 

They look incredible on 348s, F355s, and Testarossas. I parked next to a local owner's Testarossa with Speedline SL 978s at C&C.

I measured lip to lip on the wheels.
