There are two issues with lowering. Limited suspension travel and bump steer.

Lowering will decrease how far the suspension can compress. You are going to feel it hit the bump stops. Raising the spindles compensates for this. Ideally your struts should be matched to the torsion bars.

Lowering also induces bump steer because it changes the A-arm geometry relative to the steering rack. If you were tracking the car this would be a greater concern. The side effect of uncorrected geometry is you will feel the steering wheel snap sharply left/right at times (going over a speed bump).

You may also get tire rub so you could have to roll your front fenders.

You will certainly need to get the car re-aligned afterwards.

When I bought my car it was lowered to Euro height with no compensation. I completely refreshed the suspension and I'm below Euro height now. I much prefer the handling now over the way it was before but it's hard to make a good apples/apples comparison when you have worn bushings and struts as a starting point.

My advice for a street car is to not worry about the look, replace the worn out bits in the suspension, match your struts to your torsion bars and call it a day. You'll get better handling and better tire wear and spend a lot less money.
