I am looking for some lowering springs for my 87 GTA. I will drive it on the street and do some mild racing. I was wondering what springs would be the best for it. I heard that the Eiback sportlines are beter than the pro-kit because the progressive rate of the pro-kit makes them unpredictable. What are your opinons and experiences with springs. Other brands I should look at? Thanks

 

I like my pro-kit but if anything the progressive would make them handle better. A set rate spring will give more when more pressure is applied. So if you did a hard right turn the front passengers tire with the sport lines would move x distance when the progressive would move less because at a certain point the pressure increases and this keeps the car more level. I do wish however that the pro-kit would drop the car a little more. Right now I'm only a half inch lower than stock all around. If I had to do it again I would probably get the pro-kits just because they seem to have a better feel to them under normal driving conditions. The sportlines are probably stiff and low enough though that they would make a better choice for an all out handling car. Don't forget to cut down the rubber snubs!
