Auto Power Industries/DSE/Tiger Cage

[Chassisworks]

Regarding the placement of the main hoop: Per NHRA rules the main hoop of a roll BAR must be within 6" of the helmet, vertically and horizontally, but it does NOT have to be that close when you have a roll CAGE. I do not know if this is the case with any other sanctioning bodies (NASA, SCCA, et al.) but thought it worth a mention.

I ask, because Chris Alston Chassisworks builds the best roll bars. The use a higher grade of steel, because Chris understands steel. And the roll bars & cages fit tighter to the body which provides more room for people to move around... especially the driver who can get quite busy in the cockpit.

Thanks Ron! There are definitely differences. The old Alston name is still around as 'Alston Race Cars,' mostly selling parts Chris designed in the '70s. Interestingly, it was sold last year and purchased by one of our competitors.

Hope that doesn't create any unnecessary brand maintenance.

We shall see. So far the only thing of note is a bunch of our parts ended up in one of their ads on another car website. We were pretty stoked about the free exposure.

Yes. When we used to install roll bars a lifetime ago, we mocked up the driver & set them 4" away from the roll bar main hoop. Didn't want the driver's head hitting the bar ... even with a helmet. In PT cars it needs to be 5" in my opinion.

Yup. Yup. Exactly.

Hmmm. Weird. Why would a company want to use the old Alston Race Cars name.
