What is the difference in springs between the awd cars and fwd cars? I see all lowering springs are for awd cars and not for fwd cars, trying to understand the difference. I would assume spring rate since awd cars are heavier then fwd cars. But is there any other differences to the springs?

There are physical differences for the strut cartridge for the rear struts for AWD vs FWD that will affect the physical spring dimensions that are needed.

there are two cases:

(1) A FWD SL 3000gt with ECS - the spring perch is the same size but the strut column is shorter. See pic below.

(2) A FWD 3000gt w/ NO ECS - the spring perch is smaller in addition to being shorter.

So a non ecs rear would have a smaller diameter perch and shorter length overall is what I get.. makes sense. Since nobody seems to make a lowering spring for the fwd cars the two options are coilover which is a higher expense to just achieve a cosmetic look or your cut a stock replacement spring to achieve the cosmetic look which in return changes the spring rate. Does anyone have the spring rate of the fwd car in the rear? Is the strut dimensions in the front the same across the board regardless of fwd or awd ? Or is there physical differences in the front struts too?

I appreciate that info. Of course that leads into my next question. Can I take a awd rear strut and put it into the rear of the fwd car? Does it bolt up in place? Are the mounts the same between both cars?

Look at the picture I posted that shows the difference between to the two... the answer is no because they have different dimensions.... you can however swap out a rear Non-ECS FWD strut with an rear FWD ECS strut. but that only makes sense if your doing an ECS conversion.

I think Intrax used to make lowering springs for the FWD 3000gt SL's ECS & NonECS versions. But I don't think they are making them anymore... you might be able to find some used ones. looks like its part# 55.1.010 or 55.1.012 dunno which is which.

It looks like I can get some Eibach Pro springs for the FWD platform.

Front Lowering: 1.5in
Rear Lowering: 1.3in

This is for cars that did not come with ECS or the electric sunroof. $279.99 shipped for a set.

Its more than: will they fit. The vehicle dynamics are different between FWD and AWD. It takes more than part swaps in either direction to improve ride or more importantly, handling. Stick with you basic factory chassis/suspension components and seek out lowering springs for your car being careful not to go with too high spring rates. Rock hard springs will do more harm than good on the street.
