I've got the sussy done & strut bar, but want to do a little more for my Euro to improve handling..

Was wandering what other Euro owners have done to improve on handling..

I've been looking for sway bar, but the only brand I can find is whiteline..
Does anyone know of any Jap brands, neither Spoon nor Cusco seem to have them.

Also what other things are there to improve handling besides wheels & tires and not go overboard like role cage...

Thanks
