Tein S tech springs

[s13pignose]

Would there be a need for different control arms if I were to get these springs, or will a simple alignment do.

Also do they cause much oversteer? I've been fwd all my life, and by me just gettin s14 I need to get use to how far I can push the limits on a rwd. I say this because just the other day my car fishtailed on me a lil when pullin out on to the street. I'm use to being able to just pull on out in qwik situations, but i think with my 240 there's more of a limit on how much throttle input you can give while in makin a turn. I was tryin to beat the oncoming further back with good amount of time/space, and the tires sorta have lost traction with not one sign of a chirp! For all I know, it could've been a slick spot, but I think it may be a limit of throttle. I plan to take some time in a vacant lot a really push my car to get a better feel for it and learn it's limits. I don't plan on drifting or autocrossing. I just like pretty much straight line and highways, so what springs would give my car a safe neutral feel in these situations. All I know is I'd rather not have the rear come out on me in any situation.Also would a front strut bar help too?Thanks
