Brett H. - 89GTA

I am planning to rebuild my GTA's front and rear suspension this winter. Generally, I am happy with the cornering performance. The suspension is currently stock except for Koni struts. The car will be treated to LCAs, subframe connectors, etc. I would like to drop the car a bit for appearance, but am not sure that aftermarket lowering springs would preserve the ride and handling characteristics. I am considering ordering a set of WS6 springs from Eaton Detroit Spring, and specifying the amount of drop I want when I place the order. I have heard of people doing this with other makes of cars, and the pricing is supposed to be competitive with Eibach, etc. Has anyone done this, and if so how did it turn out? Also, has anyone replaced their WS6 springs with aftermarket springs and been happy with the results?
