Looking at lowering my sw20 na as the stock shocks are worn out and currently way too high (stock height) would these be a good setup?
Would run coilovers but wheel choice wont allow it without spacers and dont want to run them.

1) OEM rated shocks in tandem with lowered springs wont work well and will burn out the shock extremely fast
 
2) I don't think King Springs ride that well. A lot of this is dependent on the shock though. I tried to source some 93+ springs but people wanted ludicrous prices around here (300+) - recommend you try the UK and American forums alongside ebay, lots of good lowering springs available for cheap. Ended up shipping TRD's from America which I'm happy with.
 
The key question is: Do you want it to look good or do you want it to go around a track fast?

Bit of both really

Fork out the money and get coilovers. You won't regret it, plus you will be able to put bigger wheels/tyres on the car without hitting the tower.

I thought coilovers actually made you loose room up front

Correct, but so many variables.
Clearance without using spacers would all depend on wheel width and offset.
Many people on here could give you specifics.
 
Things to know about the SW20's suspension:
Post '92 springs ride about 15mm lower than the earlier models.
For modest lowering they are a good mod for the early models and expensive heavy duty shocks are not needed with them.
If you go much lower than that, the ride suffers due to reduced bump travel, and the lower you go the worse the handling because suspension geometry is compromised.
 
BTW if fitting '92+ springs to an earlier model you will also need the 92+ shorter bumpstops.
 

Easy enough to fix with the geometry kit I have for sale. See for sale section.
