Do you know someone in the game? As the bloke above us said, you can buy them via trade, and some discount will apply, not half price, Pedders don't reduce a lot or trade, and they're only buying them through a wholesaler. They can often be good if you tell the it's for a race car. It's been a long while since I've paid full retail.
The wholesalers for Koni's in Melbourne are mobs called Proven Products, and Top Performance. I don't know if they do retail, but it can't hurt to try. Otherwise, let your fingrs do the walking, and get a couple of quotes from Melbourne places.
As for swaybars, don't touch them until you have your spring rates and shocks sorted. Otherwise you're changing too many things too quickly. 20's only weigh 900kgs, and, in particular, don't really need rear swaybars. I've never touched mine on the 25.
Oh, and Anastasios, we don't charge by the letter. Don't be lazy, type full words.
