If wheels and tires weight a few lbs more than before. - Im no physicist but you could theoretically gain considerably more rotational mass. Any engineers please weigh in.

I also am no physicist but heavier wheels and tires create a lot more rotational enertia which reduces acceleration, makes braking worse and doesn't improve traction or handling. Generally the stock wheels are the best for most cars. Any aesthetic wheel changes should weigh the same or less to not go backwards performance wise. The spread of weight from the centre outwards also has an effect. The best upgrade is better tyres.

Larger diameter wheels will slow down acceleration and be worse for braking. The plus side is that you have a higher top speed.

The car is still awesome though...

and it looks so good...

so pulley and tune is deff on the cards

Increase top end or screw with ur speedo?

You will have a higher max speed only if it is limited by redline in top gear. Your speedo will read lower than the speed really is. None of this is a concern if the rolling diameter of the wheel is the same. If the tyres are lower profile on the larger wheel with approximately the same diameter then it will not make a difference to these two things.
