Hi,

I like the looks of XXR 530 wheels but have read on numerous websites that they suffer in quality and may not be safe to track. Some say it's not true. Aside from being heavy, are the XXRs really dangerous to track or drive hard on public roads?

Without knowing the answer, I would assume that a wheel that's even moderately dangerous for most passenger vehicles will be fine for our much lighter cars. Since you say "numerous" sites, I'm going to assume more mass appeal than our brand, haha. Basically all of the loads on a wheel are proportional to that corner's weight, so breaking on a car with an 800lb corner is not an indicator of immediate threat on ours with ~600lb on the heaviest corner (also assuming you are talking Elise/Exige). That all being said, if anyone has actually seen a failure with our platform, then their experience far outweighs my intuition.

IDK, but for the track I would error on the side of not taking a chance. (I know, oxymoron of not taking a chance while tracking a car.)

No.

They are NOT dangerous as track wheels.

The first thing to realize is that it depends on the style of the wheel. Some styles are stronger than others, and the 530 is a stronger style (meaning it has more spokes).

Second, it has a LOT to do with the weight of the car. On a Lotus you could use pot metal.

And lastly, there are many thousands of guys using these for track wheels because they are so cheap to replace, and yes I'm sure there have been some failures, but nothing close to the Lotus/Miata weight.

If you want to worry about a failure, make sure your toe links are addressed...

lol thanks and good to know. Being cheap to replace to me is not a factor when the damage caused by the wheel breaking is far beyond the wheel itself.

Another potential for cause of failure is powder coating unless at low temp....LSS Wheel failure....https://www.lotustalk.com/threads/epic-lss-wheel-failure-at-grattan-raceway.316009/

Thanks for the insight, guys. I am going to try to look elsewhere.

Light car running on wheel for heavier car, tire height not that low, on big holes on the pavement... not stressed by that.

Note that this primarily applies to forged wheels (like the LSS).
True and like one of the posts pointed out that with forged wheels a power coat at 250 deg is below the ageing temp for forged 6061-T6 at 350F
