I'd say get rid of the cats and you wont have to worry about them =) As for bushings, this company has stiffer ones: SuperPro Suspension Parts and Poly Bushings forHYUNDAI VELOSTER 2011-on - FS
For springs there's H&R springs along with Eibach. I've had both and prefer the Eibach. For shocks & struts, Koni is a great brand.
Pierce Motorsports has the best chassis stiffening components like strut bars and a rear torsion bar which is awesome. The rear torsion bar is almost a must for these cars.
