I agree with Jack, as a youngster I lowered some Fords I drove by changing the springs, wide steel wheels, bigger engine and negative camber on front suspension, so it would corner and go well also but I have seen many examples of poor "coil over " bodge jobs that the owners had to spend lots of money putting back to original due to rapid wear of the conversion kit.
Are you after looks or handling?
Given the state of the roads these days and the speed bumps, if you are going for looks it is going to be horrible to drive, so if you just want to leave it in your garage and just stroke it as you pass that's fine.

I have been in a few seriously lowered cars and anything more than a short drive to the shops, soon stops it being a pleasure to drive.

Many years ago I raced Karts and they have no suspension at all, the ride was like that!
Personally I would prefer to have a vehicle that I could use, a good set of wheels and tyres will look good and improve handling.
Have you ever followed a seriously lowered car, racing up to each speed bump, braking hard and then crawling over it with chassis and any front spoiler dragging the floor at the same time any bog standard van is going over the same speed bumps without slowing down.
That's my grump for the day, in the end it is your car to do what you want with it, check out a few car mags with the sort of conversion you are thinking about and make your own mind up.
