OK so there is a FDR limit of 4.0 ? Thanks, I'll have to buy some spurs and pinions. Maximum I have is 34.

Last year in Apeldoorn and Andernach it was 4.0.
On Anna's car we used 37/78*1,9=4,005. But you have to modify the motor mount a little bit...

Hello friends.

I am from Canary Islands. People of Xray, we are using 48p, with spur 78 and pinion 37, ratio: 4.005 as David_Ehrbar says.
But I must modify the motor mount, where you put the screws more or less 0.5mm, and in the center part.

Regards.

Hello xray users!

I am also the new user of T3 12 and I must say it is awesome car.

@David, Ruben: could you please describe me (or show me with picture) your modification to fit 37 pinion? Thank you.
