SMG with HPF clutch stage 2 - WOW

After the ESS VT2-550 install, the gears change became a bit sluggish compared with N/A setup. It was obvious that the stock clutch besides handling with no slippage from low to mid revs, near the redline it couldn't handle pretty well at this power level and was delaying a bit the shifting. S6 seemed like S3 in normal conditions.

At the time that i bought the ESS kit i also ordered the HPF Clutch stage 2 but had it in the shelf waiting the stock clutch to worn. Lately, i had some problems with stuck gears R, 2nd and 5th (or missing gears 1st, 4th and 6th). After some research, it pointed to two possible problems: broken springs or bad gear identification switch. I bought all this parts to avoid a trial and error:

Compression spring - 23311228393
Compression spring - 23111222720
Compression spring - 23317511337
Compression spring - 23311228405
Gear position sensor - 23412229792

Since to install some springs it needs to remove the gearbox, i also decided to mount the HPF clutch to avoid another gearbox removal in a near future.

After all mounted and SMG adaptation i took it for a spin. Now, what a difference... Gear shifting feels like when i bought the car, firm and quick but at this power level. Couldn't be happier with the car. I fall in love again. This car is a hate and love neverending story. I hope that this love period remains for a long long time.
