Get the works kit.
The handling kit is fairly minimal and unless you are planning on buying the other bits later its not really worth the effort.
If you are tight on cash just buy the rear adjustable swaybar and bushes to suit and buy the rest as needed.
i decided to buy the handling kit with the sway bar because my bushes on the rear sway bar were gone. The bushes that i need are all in the kit so i though why not.
It is on order. Wont get it until the 4th of march though. Whiteline say they are outa stock until then. Just waiting now. So i park the celica and take the camira.
I ran the works kit in my white GrpA for a while. Pretty good for the price. I did end up going coilovers but for 90% of people the Whiteline kit is as much as you'll ever need.
I'll be running the rear adjustable sway bar in the GT8 soon as well.
got the works kit in mine - for street use - its 100% tops ..
some guys say the springs are a little soft for trackwork - though ill test this theory out in the near future - but for a street car - its worth the lot
as mentioned - the handling kit will be good to tighten things up - but it wont feel as good unless you complete the package when you can afford it
