Options that do exist would be find any car in the yard that has the same code for a one spring replacement. If you are looking to change your spring rate, you could get a matched set of springs from a donor that is only slightly up the scale, for example the FUY springs. http://www.w-body.com/oldsite/spring-codes.html Keep in mind the following: matched springs are importants, with little exception all W's had matched front springs, except a few 3.4 dohc cars i have looked into.

2001goldGTP Posted May 21, 2013 Author Report Share Posted May 21, 2013 thanks, so it seems like i have a pretty low spring rate in the front? edit Oh so i get it, the front and rear springs are matched Quote Link to comment Share on other sites More sharing options...
2001goldGTP Posted May 24, 2013 Author Report Share Posted May 24, 2013 Can we get new spring to match or are we left with the generic ones from moog raybestos and ac delco? Quote Link to comment Share on other sites More sharing options...
Crazy K Posted May 24, 2013 Report Share Posted May 24, 2013 (edited) I was actually speaking left and right front springs are matched.

There is also a trend towrads stronger springs as the years pass.... I have not seen or documented a 95+ car that has springs not on the chart. I have always gone with used, since I can find nice clean used ones when needed... Follow the rule of having them matched side by side. If you use an aftermarket spring of unknown rate, but have a second spring as part of the set, you need to use both of them.

Crazy K Posted May 24, 2013 Report Share Posted May 24, 2013 p.s. you did say you need shocks, do you actually need springs? if you have good springs, you should have some that are ideal for the car you already drive. Firmer springs could make it ride like a truck........ where as a few of my cars could stand to get springs at about the same rate as your cars has because they are too soft.... If you need advice on shocks... I have plenty, just ask. Quote Link to comment Share on other sites More sharing options...
2001goldGTP Posted May 31, 2013 Author Report Share Posted May 31, 2013 I have front shocks i havent put them in yet. I have always had monroe reflexes in the car. My rear shocks are long dead and i need to buy some. The only suspension in the back really is the moog spring helpers. So the rear end doesnt sag but it also doesnt move, handles well rides like well like ot has no suspension travel in the rear, while the front can make you sea sick, its really a rough ride. The reason im worried about the front springs is i know the shocks have been blown for a long long time. Im waiting on the last j-tool to show yup and then i can change the front shocks. edit and since anything is better than what my current set up is, i was looking for a little more aggresive spring for fun in the corners.
