I have seen bad dealings in the past from other Corvette owners from this vendor.
All the years they have been selling high priced performance parts you'd think they at least knew the basics or engines and superchargers by now
From the general progression of mods recommended by the different forums, it seems to me that the owners are still trusting that those forums have screened out vendors who would harm their cars. The forums, of course, have no real reason to allow dissenting views, opinions & experiences since they would affect advertising revenue. I think its going to take lawsuits against the vendors & the forums to eventually allow for owners to get a true picture of vendors & to see exactly how these recommended mods affect their cars.
