I would say there is as much risk.. Just in a different wayBrian28 wrote:But I wouldn't spin at 90% a spin is over 100%. Points taken, I'm not suggesting that anybody cuts costs with safety, but the reality is that there is less risk on track days than racing. That's why insurance costs more, and why you will be kicked out if caught timing laps on a track day.
Anyone built there own cage?

we can keep this going and going. There will always be two different opinions.
It's like a motor bikers crash helmet. He doesn't really need one. Just that split second before his head hits the ground it suddenly becomes very useful.
@Brian28, I have seen people spinning on trackdays at speeds I would consider not even 70%
One's 90% speed can be differnt to somebody else' 90% speed
And I am not saying ERW tube can't be used full stop, I just disapprove undersized ERW tube. Sure you can make an ERW cage strong enough. If you don't mind adding 100kgs to your car. Personally I wouldn't spend the money on T45 for a trackday car, normal CDS is good enough for me. Not only the cost makes using T45 more difficult, the fabrication skills and tooling required are higher as well. If a lightweight car would be my goal, I would use T45 as well.
A bought core cage with ready bend tubes will enable the semi skilled/equipped fabricator to build a fairly good cage at home offering reasonable saftey and cost.

Not a chance I would get in a car with a DIY cage no matter how good the builder say's it is.
Just my personal opinion.
Seen to many crashs that don't look to bad racing, which could have easliy happened on a trackday where a good cage made all the diference.

just have a look at this picture. Maybe some people will think twice about building a cage themselves. Driver walked away with a broken arm as only injury as far as I know.
And no this was not in a race, just a driver training on the Nuerburgring.

Well it's a German registered car so the cage must have TUV approval. To gain this approval the product has to have undergone significant testing, so it would be a fair assumption to say it is manufactured by a reputable brand. The TUV examination will also ensure that it is properly installed, something which an intrepid DIYer might not manage.agent006 wrote:Who built the cage in that picture?
I know on what part of the track the accident happened (170mph section!) and I still have shivers down my spine just by looking at the picture.GeoffBob wrote:I'm surprised they could find his arm after that accident. Ouch! Great example Uwe.
Wants me to fit a few more pipes to my very own 11 point cage!
The vertical one down the A-pillar to the floor to re-inforce the bend at the roof (forming a triagle) as required in all new touring car cages and rally cages.

So did I initially, its only when you see the pics of the drivers side that you can see that it was a 2dr m3Jon_Bmw wrote:I thought it was a Z3M coupe!
