Ive just found out that my two front tyres are bold on the inside. Its bold on the part nearest to the engine. This tyre place said that i might need castor and camber kit. But he also said that this might not fix the problem. He said it might cost around $400 for the kit. Just want to know how much should the kit cost and will it fix the problem. Or is it bad wheel alignment?

i had the same problem on the ea,,got a wheel alignment and all is ok now.

Camber castor kit costs about $250 no more. That should include fitting and alignment. If not $300 is the most you would pay.
Will definitely fix the problem as long as you keep your tyre's at the correct pressure.

I had the same problem with mine and was told that the kit would fix it and it did but only after the lower control arm bushes were replaced. So if everything else is in good nick than the camber castor kit will fix it....
