personally i would change to a trd quickshifter gearstick, £200 ish from prolex-uk.
its subtle to say the least, in fact only you will know you have got it, if you want others to see your mods then it needs to be something cosmetic like a spoiler or full bodykit, eyebrows, painted calipers and stickers etc...
obviously depends entirely on funds available, if your like me with limited funds go for things like painted calipers and stickers, eyebrows, etc. if your well flushed then the worlds your oyster and anyhtings possible.
go to the garage and see what the guys have done
