GC8 first upgrades

This is my imported GC8 from Japan 🇯🇵 to the uk 🇬🇧, it’s a completely original car besides the radio, I’ve had it for a while now and I’m looking at getting its first few upgrades starting with breaks and suspension, I’ve been looking around at whag options there and I’m wondering if there are there any GC8 owners out there that can share what they use or any suggestions?
