you’ve already got some solid advice from Jack and Maarten. This is what I can say from my experience:
If you’re on the stock wheels, I definitely recommend 165/60/14 Toyo Proxes CF2 on the fronts. They are amazing tyres and really improve the handling.
Secondly, if your on a tight budget, then I recommend 35mm lowering springs all around, they help to eliminate a lot of body roll. If your on a bigger budget, then go for some proper coilovers.
Lastly, just to make the car feel more direct and fun to drive, I recommend a Nissan pulsar short shifter kit (from eBay) as this makes the gear changes much more quicker and some reinforced engine mounts - HardRace is usually the company for the engine mounts.
These mods will make the car much more better to drive and more like a go kart. If you want to make the car quicker as well, you can put the 1.0 gearbox and 1.0 flywheel in as this noticeably improves acceleration.
