I think its the questions and not thinking first mate. 4.11 is very low low for a 6speed. I wouldnt even put them into my ef on the street.

So do you currently have this car? Or just asking for the future?

I pretty sure that 4.11 gears were originally for cars running 30-inch or taller slicks, a long first gear, and wanting to hit the end of the quarter-mile doing almost redline in top gear. Probably not very practical for a street car on 25-26 inch tyres running a 4.17 first gear (that's 17.1 turns of the crank for one turn of the axle). Even the 2.39 first gear of the BTR 4-speed can get a good launch with only 3.9 gears (9.3 crank to axle ratio). Anything more than 3.45 with the ZF, and the car will probably be ahead of the engine, waiting for the revs to catch up
