nice car mate, mine was much like yours except i got carried away and its not much like a bonus now.
i would say looks wise its a good idea to decide which way you want to go and stick with it, meaning if you want it to look standard like a sleeper then maybe go 15" steels and try conceal the exhaust a bit, they can look just as good as a car with spoilers etc with alot less work.
once i fitted alloys / rs bonnet and roll cage i decided mine looked too modified to be a sleeper so carried on going with it.
engine looks good, was the mouning the same?
