1.5 Drop Springs
I am unsure of brand, but I have a set of 1.5" drop springs, brand new. All are still tagged front or rear. Front were installed momentarily but never compressed. 125 plus shipping.

Re: 1.5 Drop Springs
That's what a tgo member sold them to me as new in the box. Over the last couple of years the box fell apart, I installed the fronts just to roll my project then decided on air ride. I wish I could remember the brand. I know they were eibach.

Re: 1.5 Drop Springs
if they are 1.5 drop eibach they would be the sportline springs which are red, the eibach pro-kit springs are black. they look like intraxx or hotchkis springs to me.

Re: 1.5 Drop Springs
thought i remembered seeing gray hotchkis springs, but i may be mistaken. however im certain the sportlines are red, i have a set on my GTA and have installed pro-kit and sportlines on a couple other cars. there's so many spring makers out there its tough to keep track LOL

Re: 1.5 Drop Springs
Never seen any of the big brands not have there logo on them somewhere. I'm interested but not enough to take the risk and buy them. Without a box or some proof as to what they fit, uncertainty of the brand and question the amount of drop its just a bit to much of a risk. Take less than asking price?.

Re: 1.5 Drop Springs
My 1.0"-1.5" lowering springs I got were from summit racing. They were painted grey kinda like these. I do remember mine had a part number in ink on them that started with the letters SUM followed by numbers but can't remember what the numbers are. They came in a plain white box. Maybe this could help you identify them.

Re: 1.5 Drop Springs
I removed the fronts from my roller and found a tag labeled Suspension Technologies... So there ya go guys. The fronts have a couple specs of rust in contact areas but that's it. Im having an impossible time posting pics from my phone at the moment but I have pics of them next to stock springs and they are definitely 1.5 or 2 inch drops. They were sold to me as 1.5's so I have no reason to doubt it. Definitely shorter and beefier than stock.

Re: 1.5 Drop Springs
I wanted to let you know I got the springs installed yesterday. These springs are unbelievably great. The stance is mean. The handling is quite excellent. Turns and curve are very responsive. No flexing, nose dives or squatting. Thanks hardcorezcar. I have never enjoyed my car so much.

Re: 1.5 Drop Springs
Glad you like them and the new stance! Hope they went in nice, they did for me bc they're short enough to not need to compress them to install. Got plenty more suspension parts so if ur ever in the market for more, look up my threads. Thanks again for the sale bro.
