Wheel Alignment- Camber kit?

[WannabeXP]

G'day everyone!
So i have an AUII xr6 thats live axle with 18" Azzuro wheels and SL Kingsprings in the front.
I went and got an alignment done today locally at Goodyear Autocare here in Warrnambool and they only adjusted the toe and claimed i need a camber kit.
I did ask them to do it but they wriggled and squirmed because the car is on gas!
Anyway i had the impression before i lowered it an inch or so more then standard that i wouldn't need a camber kit just an alignment. After that i did a bit of research using the search tool and found out a little bit but my questions were not directly answered.
Now i didnt get provided with a printout, they charged me fullprice and they haven't laid a spanner on the UCA mounts which upon further research actually have around 10mm of thread left in them.
So this sparked some anger and swearing once i found that out!!!
Anyway so the question is do i actually need a camber kit? And i do know its hard to say without figures!
Also what tyre pressure should i have in my tyres if they are 245/40R18??
The tyres are completely stuffed due to the camber and Goodyear definitely did not want to help me out!
I will endeavour to get a printout and possible explanation from goodyear but i dont like my luck! Imagine how many people they have been ripping off who would have no idea about a wheel alignment in general!
Tomorrow i will get pictures and if i can get a printout i will upload a scan
Cheers in advance!!
