Calkulin
Ready to race!
My 2 cents on the controversy...
All clutches are sourced from big manufacturers, so all retailers tinkle with parts or not, repackage and sell for profit. Fair enough. HS Tuning resolved a problem, fills a demand and makes a profit. Nothing wrong with that. How much do they actually modify parts for their solution (other than sanding part#) is in question. But at the end of the day, people are willing to pay a premium for a boxed solution, customer service and (I hope) a warranty should the solution fail.
Calkulin on the other hand is able to cut R&D because he has the RSR clutch as the model. He was able to figure out that clutch can be sourced piecemeal, requires a minor modification and can be had for half H&S Tuning's clutch. If anything, that's the power of the internet and forums such as this one. There will always be guys like Calkulin out there and I'm thankful for this.
Eventually H&S Tuning will need to lower their price to a competitive point or just drop the business if the effort is more than the return. I hope they've sold enough clutches to justify the time they spent figuring out what works because sanding OEM part# is not value-add. But I'd think there is still a business sourcing/packaging/retailing/warranting RSR clutches to a general public not accustomed to doing what Calkulin does.
Agreed with you 100% but there 1 correction and I amended my post to add that. And remember, this is not just my modification, HS Tuning has to do the same for the TSI version they sell
