What is the best suspension for improve handling and lap times?

Back again... Optionzero pretty much stated it correctly as is with his first reply. Tires being the most important piece out of all. Track abuse will destroy normal road tires not meant for extended heat cycling. Same goes for normal road bushings that weren't designed for extended lateral g-force. Once your bushings die out, you will be chasing alignment problems and steering feedback troubles. So tires and bushings are numero uno. Safety is key, being fast is a goal. Don't have anything to add in terms of companies to choose from. But JIC magic has gone through an evolution in the past years and are offering bespoke kits. Their customer base isn't too deep, so you have an opportunity to get some good one on one info from the team. They can definitely meet your price point for a custom kit with good spring rate options.

You should talk to tuning experts that can give you the best spring rate option for the height you are trying to achieve. Companies like performance shock inc or vorshlag can help you with this far better than suspension companies who mass market kits for several cars. Most suspension companies won't even be able to properly tell you the spring rates for half the kits they make without reading a chart.

More important than just buying a suspension kit though is making sure the car is properly corner balanced before you even hit the road. You'll need to find you nearest suspension tuning shop to figure out if they can do this for you, or find a way of getting the car to a shop that can perform this service properly. None of the kits mentioned previously sets the spring alignment up perfectly for your car right out of the box. So you'd want to set aside about 250-500 dollars to chassis alignment after the suspension install. People end up chasing geometry related problems for years because of this oversight, don't fall into this camp.

Also note, after the installs, an alignment should be done before and after corner balance for the best results. Once to set the suspension linkages to a neutral position then again to insure the values are set as you want it for intended use. This isn't absolutely needed, but at the very least do the corner balance > alignment if the tuner doesn't have the proper tools to handle this all in a single instance.
