Just doing some upgrades and wanted some input. I want to run my car on a track and build my set up around that so I was thinkikng of a few upgrades. For the money, how well is a z32 front and rear upgrade for braking power? also what suspension would performe well on the track,cornering ect. Ive heard good thinkgs about HKS suspension. also I need some input on flywheels. Is it worth the money for the more expensive brands, or can i get away with a cheap flywheel?
