Well, because I am not Dinan and I am a one man operation with a day job.... I cannot get too deep into developping or manufacturing parts that don't sell.
I learned my lessons on the MAF, did better on the oil canister kit for the M30.
Now I just want to supply dirty cheap parts that improve the car without breaking the customer's piggy bank.

This link is for installing the 320i transmission mounts instead of the weak E34 / E32 ones.
I installed them on my 535i and sold them to a couple of customers. They are pretty stiff and are very cheap.
They are stiff enough. I could develop something like the enforcer and make a huge batch of them, but I don't know if enough people would be interested.
By the way my 540i rear brakes are for sale again: Vented Rotors + callipers + carrier + clips: 150 US + shipping cost.
