The height they specify will be fine for your car being a GEN4. They were already low from factory so it might not drop that far. 20mm max maybe. The early cars are 20-30mm higher than your car so that is where the additional height comes from. 50% off all SW20s were GEN1 with 4WD height suspension.
As for spring rates
Front 130lbf/in is 2.321Kgf/mm or 22.76N/mm. TRD in comparison is 29.4 N/mm
Rear 240lbf/in is 4.285Kgf/mm or 42.03N/mm TRD is 53.9N/mm for soft and 60.8N/mm for hard.
According to sources on the internet stock is 130ibf/in front and 210ibf/in rear but have a linear rate where these springs are not linear like most aftermarket springs.

So putting the springs on will make the ride firmer and drop it a little bit?GDII wrote:The height they specify will be fine for your car being a GEN4.

Re: geemannz's 1997 SW20
So unfortunately after all my efforts in fixing this car. It still leaks oil like a sieve.
As much as I love this car I think its time to hedge my bets and sell the car.
It [Expletive Deleted] sucks but I cant afford to keep trying fixes and buying oil on my student budget
If anyone is interested flick me a PM.

Re: geemannz's 1997 SW20
That's a shame considering how much work you have done and one would think that this is a rather simple fix. Have you had any experienced mechanics look at the crank oil seal issue?

Re: geemannz's 1997 SW20
I'm going to try and get the lower timing cover off and see where its leaking from again, but at the moment I cant afford to take it to a mechanic, hence doing all the work myself. Fortunately my situtation changed a litle bit since the last update, in that I have access to another car at the moment, so I can justify trying a couple more fixes.
