Ineresting Info about BBS Wheels

jimlai322 · 12-07-2007, 02:42 PM

They talk about die forging vs regular forging if anyone is interested. Also information regarding upgrading to larger wheel sizes.

what a BIASED and MISLEADING article.

"Rather than using the cheaper and more common A6061 Aluminum Alloy... BBS wheels use a more superior (and expensive) aluminum alloy".

To the person who knows nothing about materials and wheel construction technology it`ll surely impress. However, it is obvious their wheels are made using a higher grade aluminum than A6061. A6061 is only used by low-end gravity cast manufacturers. Why don't they list what grade they use? Maybe because it is the same A6061-T6 used by everybody else? Including Volk? Neez? MORR? RAC? Champion? and dozen others?

I highly doubt they use A7075-T6 aluminum on their wheels. Although the 7075-T6 aluminum has a much higher strength to weight ratio, it does have a higher tendency of cracking than 6061 T6 does and weights more.

Also, BBS-Japan uses 5000TON of forging pressure versus the other manufacturers using 8000-10000TON in the same 3-stage process?

FYI, all die-forged wheels are built using a 3-stage forging process.

BBS wheels are great, but I applaud BBS-Germany for their success and innovation and feel a terrible shame about BBS-Japan releasing biased and mis-informative articles to get their company out of bankruptcy.
