Yes, stock buckets. What do you plan on triangulating the bar to? Something like this?

I don't see much of a point if you have a strut tower bar as that will box the top of the suspension. I have the Mazdatrix one (seems like they don't make it anymore) which triangulates into the firewall and is very rigid. I haven't driven the car with the lower arm bar yet but I notice a difference when jacking the car up.
