Front and rear arb size

[Phill]

Hi folks, does anyone know the size of the front and rear ARB on my V6 DTM reg N550 EBK. Im buying poly bushes and the part of my copy of the vauxhall epc that you put your reg or vin in to doesn't seem to work so i cant get vehical specific info. The generic info lists 2 for the front 20mm and 22mm for my engine but it doesn't give a size for the rear.

Most are 22 front and 15 rear. I've never figured out what cars have what arb sizes There is a size bigger and size smaller too.

Safest way is to go check the width with a spanner (easiest way)

i will do that on my days off if its not under a foot of snow as my spanners are easyer to get to than my digital calipers.
