Correct, these rims are from a 355 Challenge race car which was located in Southern Spain. Magnesium and extremely light. Cannot be polished, shouldn't be chemically stripped and should not be oven baked. These have just been sanded and wet painted. The original CH rims just had the Speedline logo in black. Later Speedline rims had the new Corse logo as well, which i've added as i personally like the contrast of the orange Corse decal. Strictly speaking though, these rims should just have the Speedline decal in black.
Nice run today and suspension settled. Dropped it 18mm and running spacers f & r - no clearance issues Image Unavailable, Please Login
LOL... Crap you need to lighten up, I wasn't pissin' in your Cherrios or on your wheels(referring to my post 172) I even apologized for disagreeing with you. In fact they look great, I was simply stating they are not the same wheel used on the 355 CH end of thought and comment in my post.
You take yourself too seriously. Who twisted your nickers? It isn't a big deal to me at all. No need to get volgur.
Yep, thanks, they are Speedline but I don't remember the model number. I just like the look, don't intend to race the car, heck, I would just run off the track anyway.
I may be wrong but this is the advice from all of the major wheel refurbers in the UK. As they're magnesium you have to be extremely careful when stripping. Chemical stripping reacts very badly with magnesium and can result in serious bad pitting and erosion. If the wheels have been previously powder coated the only effective method of stripping is to use chemicals. Bead blasting is ok if done with very fine blast material - unfortunately this isn't aggressive enough to remove powder coating effectively and you're then back to chemically stripping - a big no no with magnesium Due to the magnesium wheel casting process it is not a good idea to oven bake mag rims at high temperatures as this can cause the rim to weaken dramatically due to the nature / structure of the material Every wheel refurber i spoke with, would not touch them and simply recommended just flatting off and painting conventionally. Again, i'm no expert - just explaining what i have been told and why these rims need so much care when refinishing.
OK, these aluminum Speedline CH wheels look pretty good to me. And frankly, after reading the post by Candellara, the magnesium wheels sound like a bit of a PITA. So does anyone know if the aluminum ones are still available? I found this contact info for Speedline America: Speedline America Corporation Bill Hoffman, Operations Manager 1177 Sawgrass Corporate Parkway Fort Lauderdale, FL 33323 954-846-9234 I left a message but haven't (yet) gotten a call back. The answering machine message provides no identifying info, and sounds like a residence, not a business, so I have no idea if I'm on the right track... - Eric
You think they would look good black ? Never thought about it at all. I will tell you the car looks fantastic with them in white.They may go back to white yet . Image Unavailable, Please Login
Hi - When I decided to buy a 348, I also decided I eventually wanted different wheels than stock. After looking at options, I decided I wanted to try to find challenge wheels. I PM'd Dino, and since he had not sold his yet, I decided to buy them! They're black, but I'll have them refinished in silver. Haven't had a chance to talk with him in detail yet, but had a few questions... Can anyone confirm if the challenge wheels are also 17" and same width as stock wheels, and so take same tire sizes as stock? I searched for 348 tire recommendations, and not surprisingly, there are a lot of different opinions and experience with different mfgrs. I'm still interested in recommendations. My plan... mostly street, but may want to participate in a track day or two, or other club events, slaloms (is autocross the right term?), etc. I'm sure I'll replace them on age rather than wear, though, so would probably like softer compound/best grip. I live in Phoenix area, so rain not much of a concern. One other question...348 workshop manual recommends Pirellis or Bridgestones. The manual includes this caution statement..... " The Bridgestone tyres must carry identification code DBM for front and CHJ for rear. Tyres on the market with different identification codes, such as CHK for the front, are produced by a lower quality production process and are therefore not suitable for these cars". Are these codes are for non-US locations, and similar to ZR, etc. ratings here? If not, anyone know what these codes are referring to? Thanks for any input. Rick
Another set just popped up for $3g http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33620&viewitem=&item=360032550832&_trksid=p3907.m29 Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
seems fishy it says pictures are not of the actual wheels being sold, although feedback is pretty good....
