That's great, then. Do they have the floor mounts too? If not I'd do the VAC ones ... but ask Corbeau which ones they recommend.
Better off getting the whole race seat installation kit from VAC, IMO, the quality of aftermarket kits can vary widely.
Yes I get a single chime when I turn the car on, same as if the seatbelt is not plugged in. Only sounds once. Beware the passenger has no airbags unless it's coded in.
