I have purchased a new Rear 22mm adjustable swaybar
I ordered a BSR36Z to fit an 03-07 WRX
but I recieved a SR33Z for a 01-02 WRX
I will phone my supplier tomorrow but can anyone tell me tonight if these bars are the same, or not

They are not the same bar - different part numbers ..

Both are rear 22mm adjustable, but the BSR36Z is for 03-07 and the BSR33Z is for 00-02. The one you recieved will not fit onto your car.

"Wrong fitment".

I phoned my supplier and they told me I have the correct bar
I also phoned Whiteline to verify this.
So for future reference
Whiteline rear 22mm adjustable swaybar kits BSR36Z and BSR33Z use the same bar
the bar may be marked as SR33Z
but the kits use different bushes to suit 01-02 WRX and 03-07 WRX

Kit BSR36Z (03-07 WRX) uses Part Number: W0406-22 as pictured below
the difference being the flanged edges
these bushes are marked 5087-22



and kit BSR33Z (01-02 WRX) uses Part Number: W0404-22 as pictured below
