Personally, i'm not a huge fan of M030 cars. If you plan to do Stock class pca events or auto x, they make a great car.
However, for a daily driver...the suspension is not as composed as a standard car. Its bumpy over uneven surfaces and wanders a lot more then a non m030 car. Also if you plan to modify the suspension, you would be replacing the most of what makes the M030 different anyway.
I'm very content with my set-up. M030 Front Sway bar, Lindsey racing rear sway bar, Koni adjustable front & rear, H&R springs up front, rear ride hieght adjustment (lowest setting), D1 Sturt Brace & lower chassis brace, & weltmeister rear chassis brace. Chassis is stiff, body roll is minimal, & its much more composed over bumps & eneven surfaces then an M030 car.
I can say, the M030 cars are slightly more fun to drive as they feel more tossable and its easier to bring the rear out then with my car.
I also have an LSD & Factory Turbo Spoilers.
