You seem to have bought just about the entire whiteline catalog shane. If i were you, stop thpone mods and start driving the car more. From what i can see the setup youve got should make it an absolute weapon.
Too me changing alot of those small things ie transmissiob mounts etc are alot of 1% things that would only count if your aiming for top ten positions at twilight speed series etc.

Start to drive it in the youve set the car up to & use the cash on ebtering stuff & replacing bits when you need new ones.
