"red, it might be even possible your 95 springs are sagged, they are after all, only made 5 years after your 90s springs..."
Quite possible

But the comments I made in my previous post were about the ride height of the '95 Bathurst springs that I now run, compared to the new Prokits that I had fitted earlier.
Sagged or not my '95 Bathurst springs ride noticeably softer than the Prokits, especially on the front. (with Koni's on the softest setting)

On SW20's many people are surprised at the ride height they end up when fitting aftermarket springs. It appears that manufacturers quote the drop of their springs compared to brand new unsagged OEM '90 model ones

It must have been full soft for him to make that claim. Couldn't find that particular thread but this guy think 93+ springs are softer or mushier than OEM.

But feelings are subjective and I'm not here to say who's right or wrong but trying to strike a balance I guess.

How firm did he have his konis set tho? In my exp the damper adjustment can make the ride go from soft to stiff regardless of spring rate.

Yep, stock 90's suspension system. Caster is maxed out on my car between 3-4 degrees. There's just no more thread to dial further says my sussy mech. I will have a look at my toe settings (to dial more oversteer hehe" />)

Hmm according to the specs I have on Pro Kits which are 1.8-3.75 kg front and 2.5-5.4 kg rears it should be softer ride during low loads in theory but I guess real life is not the case. But I have come across someone in a thread maybe on MR2oc (where I've been lurking recently) that thought his Pro kit + Konis were soft.
RSR springs is also another manufacturer with lower rear height. This is an excerpt from an email to RSR that was sent by an MR2oc member:

"Also, what is the advantage of having the rear of the car dropped lower than the front of the car?
- The car drop design is to make the car level. Many cars come from the factory slightly higher in the rear, or in the front, and the RS*R springs compensate for that, creating a level chassis to maintain proper balance."

Hey Tree, what caster do you run?
I assume you have the early adjustable caster rods, so if you can add a bit more caster, it may help with understeer. (maybe a nice cheap mod for ya)

Re springs:
Some minor details I found with Eibach Prokits.
Although similar, there appears to be slight differences in the ride heights between them and later ('92+) OEM springs.
Compared to stock '95 Bathurst springs, I found with Eibach Pro-Kits my car was higher (10mm) at the front and lower (8MM) at the rear. The result was I didn't think the heights matched F/R
The pro-Kits also rode harder. The comparison was made with Koni inserts on the softest setting.
The Prokits are also about 2kg per spring heavier than the stock springs.

If I didn't already have the Koni's I would be looking at bc racing or something similar.

Hmm you make a good point lol. I think I'll be happy with the RSRs :)

Lol, plus camber plates and then its over the cost of kws.

Why konis and sleeve kits over something like bc?

Konis are about 1k plus the sleeve kits for 600 then add the cost of cutting up your shocks and welding etc.....

I advise against it. Sleeve over kits dont give you proper control over height adjustment without also affecting spring preload etc.

Esp if your thinking of letting it go in a yr, get bc or even try ceika.

hmm that looks like a good alternative for GC sleeves

Instead of using the Ground Control sleeve kits, look into the HSD ones.
They come in a bunch of difference sizes, $299 / pair and any spring rate from 2kg/mm - 20kg/mm. If you decide you want different springs in the future, they are $100 / pair

They also have universal camber tops for $299 / pair, if you want to go all out .

I'm feeling pretty lazy gathering all those parts lol. So the stock spring perch won't be used? I think it's definitely worth while doing that if your racing competitively.
To be honest I'm probably only gonna keep the car around 1-1.5 years which is why I don't wanna shell out for KW V3s and trying to minimise any more labour put into the car lol

I also was looking into gc sleeves. I emailed them with the correct strut sizes and got no reply.

There is a thread on mr2oc on the subject of coilover sleeves. It even includes links where to but all the components to do it.
http://mr2oc.com/showthread.php?t=411555

Have a read and see what you think. I'm not real keen on the camber plates that are suggested I think I would prefer cusco or similar.

Yeh I considered Eibach pro kit and TRDs but like MRTurbo said it's probably a bit soft for track days and would necessitate the need for aftermarket sway bars. According to the guys over at MR2oc, no aftermarket springs for the SW20 are linear (to a certain extent at least). The H&R and RSR are progressive but are designed to be more linear apparently. Interestingly, the stock SW20 springs are linear.
The King springs sounds like they would be similar to Eibach and TRDs since it feels good only after "taking a set".
I was looking for Ground control sleeves for the SW20 but looks like they only make it for AW11s so we probably have to design our own stuff. On the other hand aftermarket selection for SW20s should be wider hehe
