So my BMW DTM shiftknob arrived today. It is surprisingly light and quite tiny.
It is about 2 1/4 inches tall and measures about 2 inches wide at the head. Insertion depth of the shifter is right about 1.5 inches. But this **** is actually threaded unlike other BMW *****.

I will weigh it tomorrow, but it is most likely one of the lightest ****. That brings up the Q, why do German Touring Car racers have the lightest **** and we seek out the heaviest ones? :-) (I do understand the idea of a nice weighted ****)
Cheers,

To save weight. Every gramm of weight counts on a race car. Most important is roataing weight. I occasionally race radio controlled cars and weight matters. The general rule is if you can save an ounce of rotating weight it is like reducing non roating weight by 4 ounces.

Heck most race cars now use sequential gear boxes and paddle shifters. In WRC they have paddle shifters and a shift lever that can also be used to activate the emergency brake.

 

I know that it is about saving weight, my dad actually raced Rally cars in Germany. But I was a bit of a smartass that people pay extra for a lighter wing or bonnet and then add heavy shift *****.
Cheers,

Post pics of it on the car. I love it. How much did it go for, if you dont mind me asking ?

 

How are you going to attach it?

 

i like a lighter one... I want positive control of the ****... not the other way around... oh well to each their own... but whats the height gain or loss on this ****?

My Sparco **** i love it,wouldn't trade for all the tea in china.

 

haha...my all-time favourite Peter Griffin quote:

Peter is seen at a Free Tibet rally at which he says to a protestor "I'll take it"

He then calls China saying "I have something you may want, but it's going to cost you...."


"...That's right, all the tea"

 

That is something I'd like to know too. :-)
