hmmmm. the expression 'we all gotta start somewhere' springs to mind.
sadly, I doubt there is anything on the car that makes it go faster than it did before but never mind.
ground wires on the HT leads are for one thing only - to get people to pay 50USD for a set of HT leads in the belief that they make the car go faster. with the exception of possibly reducing radio interference, grounding your HT lead is the last thing you want to be doing!
still, it's a bit of fun for the owner and his mates and one day they may all have modified Skylines, NSX or whatever, then those badges will come in handy.
What it really needs is a set of shocks and springs to get it much lower and stiffer, and then something to make it faster - either strip all the interior out except for a pair of lightweight front seats or engineer a turbo conversion for it. or both.
and why do people insist on painting brake drums in bright colours. it's like an ugly person in a small swimsuit.
