Spring questions

I have a 95 3dr hatch with tokico illumina shocks and some APC adjustible springs but looking for some better springs to get rid of some of the amount of sag in the turns. Does anyone have any good suggestions? I've looked into tein s techs, but dont know if they have the performance quality I am looking for.

Also on a side note; I have some 16's with some 195/50's and was wondering if anyone can tell me if there's any way to go for a wider tread width or not? My uncle said I could go with some 205/40's, but I dont know for sure and I dont know the rim width have kind of been lazy about measuring it.

I don't have any complaints about them. They are a huge improvemnt over cheap coilovers(I used to have hp racings, very poor). What is it your looking for, drag launch types, good auto X, etc.???

looking to get spring that will handle track racing.

might want something better than s-tech then.
