mate do another wheel alignment, they probably got a dodgy 1st year apprentice to do it or something.

when i first installed my coilovers i didnt get a wheel alignment, went and got new tyres, 4 weeks later it was worn to the wire of the tyres. went to get a wheel alignment, the mechanic said my toe was in about 20 degrees, which is bad, cos i understeered alot with when it wasnt aligned, after that it was all good.

just do it again
