Hello, thanks a lot for your review
I really appreciate it
Spline hard to fit: it seems that the cutter tool became a bit worn while manufacturing the batch and some sample loose that 0.05 to 0.1 mm on clearance which makes the spacer require more force to slide into the steering wheel.
Sorry for this, I'll take more care in the next batch.
Stalks/wiper levers far to reach: this is something everybody has to get used to, after fitting the spacer. Everybody says that it's a little minus compared to the advantage of the improved driving position. If I could move the whole stalks/wipers/steering angle sensor group together with the steering wheel I did it. But this involves much more parts to be made and to make a good job it will be necessary to re-mould the plastic shrouds where the stalks/wipers come out from. At the end of the job, doing something that looks like OEM (and in a Porsche is a must in my mind) will cost MUCH more than the current price of my spacer.
