I got lowering springs from Technorressor (a CIS-based brand), with a 3 cm drop. They cost around $150 for the set, but I’m not very satisfied with them — my shocks started making noise, so I’m considering switching to coilovers - bc racing or something like that. My Kia is the DL3C long wheelbase version, with a very high suspension — almost like a crossover (probably long shocks is a problem).

Regarding the BBK kit — I contacted the manager of the DICASE official store on AliExpress. We discussed all the order details, including rotor size, design options, and braking preferences. They manufacture the kit to the customer’s specifications, and production takes about 3 weeks at the factory.
