  • Advice for deciding between H&R springs or RS*R race springs with Koni's (p.2)

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.

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

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

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

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.

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."

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.

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

"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
