Roof spoiler effectiveness

[Chris Percival]

I run this wing, and from track experience, it makes a big difference to stability from speads as low as 60mph...

Talking about aerodynamics without wind tunnel testing is the same as talking about horsepower and never going near a dyno.

Some good reading.

Reading that and then going there are the only ways you'll know if anything you do is worth it. Otherwise you could be making things worse than they already are. And lets face it, is a Type4 powered Beetle ever going to handle or have a top speed warranting any sort of aerodynamic change?

Trogdor,

Take a look here under 'Feature Articles' for a reprint of 'Käfer-Cup Beetle vs Porsche Carrera RS' from Sept. 95 VW Trends magazine...

I think it just might open your eyes to the quickness/speed that the 'lowly VW' can actually accomplish...


Take care,

Agreed, however laptimes don't lie and you can't negate experienced driver feedback(I'm not in this group). For myself, I have a mechanical engineering degree and have studied a lot of the science behind it, but I can't attest to what is most effective on the track.

Yes?

If anyone has driven a super beetle in 80-100kmh wind without a kamei front spoiler and then bolted one on.........nuff said.
The wife fought the idea of a spoiler until we took our first trip on the highway with it. Huge difference even with cross winds and semi's passing.

Hi

I agree, I recently fitted one to my daily 1303, now I only hear the wind and don't feel it.
