use those which are made for tezza's cause different cars have different measurement dimensions.. unless u are talking abt those GT wings.. most of them are universal, but please do get a good gt wing if u ar considering them if not it will really downgrade your car bro!
I'm quite sure there are alot of ppl using Toyota Supercharger pistons on their GSR or 4G93 BOT. I guess there are also alot of ppl using it on reboer 4G91 and also 4G92.
