thanks again guys i was looking at the suspension and hub i know i would need bigger wheels but i was unsure of size.

if i were to go above 15" wheels iam concerned about speedo error because the old girls ganna be road legal and i cannt get any speeding fines or i wont keep my job. i was woundering if programming the ECU on my new engine will correct this or not as vauxhalls you can program them to run on different sizes and it corrects any speedo error. (the guy iam getting my new engine doesnt know anything about cars he just drives them.
